TRACK_IDENTITY (53000)

Correlation spine for the kill chain. Binds one real-world object to a globally-unique track UID that persists across find, fix, track, target, engage, and assess, so every downstream report can be tied back to the same object. Carries the basis of identification (method + confidence) separately from classification, and lineage when tracks split or merge.

This message asserts identity and how it was derived. It does not assert engagement authority; see TARGET_AUTHORIZATION.

Field Name	Type	Units	Values	Description

atr_conf_tier	uint8_t		MAVLINK_M_ATR_CONFIDENCE	OPTIONAL advisory display tier derived from atr_confidence_pct. Not for automated ROE.
sidc_context	uint8_t		MAVLINK_M_SIDC_CONTEXT	Reality context (MIL-STD-2525D SIDC digit 3): real-world vs exercise vs simulation. Prevents a live track and an exercise/simulated track from being indistinguishable on a joint net.

TARGET_CUE (53001)

Non-kinetic point-of-interest cue relayed from a sensing/ISR platform to one or more consumers (e.g. a manually piloted aircraft, an OSD, or a GCS) to direct attention to a WGS84 location for observation or investigation. Carries the geolocated point and minimal context only. It intentionally omits the authorization token, weaponeering, and CEP fields of the fires-related messages so that ISR cueing is cleanly separable from engagement on the wire.

Bearing and range to the cue are NOT transmitted: a consumer computes them locally from this point and its own GLOBAL_POSITION_INT, so the same cue is valid for every receiver regardless of position.

target_class and target_force on a cue are the SENSING platform's provisional read at detection, qualified by confidence_score - a starting hint, NOT an established identification. A cue does not identify or authorize; identification is carried on TRACK_IDENTITY and the engagement decision on TARGET_AUTHORIZATION. A consumer must not treat a cued class or affiliation as confirmed, and must never derive a release decision from a cue.

target_class	uint8_t		MAVLINK_M_TARGET_CLASS	Provisional target classification from the sensing platform, qualified by confidence_score. A hint, not an identification.
target_force	uint8_t		MAVLINK_M_TARGET_FORCE	Provisional force affiliation from the sensing platform, qualified by confidence_score. A hint, not a combat-ID determination; do not use as a release input.

PARTICIPANT_POSITION (53003)

Friendly-participant self-report of identity and position (PPLI-style / Blue Force Tracking). Distinct from target/cue messages: this is a network participant reporting "I am here, this is who I am" for the common operational picture, mappable to Link 16 PPLI, VMF position reports, and Cursor-on-Target friendly events.

Structural placeholder for joint interop; identity/type value sets and any external track-number encoding are per STANAG 5516 / MIL-STD-6017, to be reconciled from spec.

MAVLINK_M_ACK (53004)

Generic acknowledgment for MAVLink-M messages. A recipient emits this in response to an acknowledged MAVLink-M message to close the loop on delivery and acceptance, addressed to the system and component that sent that message. Keyed by the acknowledged message ID, an instance identifier (e.g. cue_id, target_set_id, or sequence) and that message's time_usec, so the originator can match the ACK to the one message it answers. The acknowledging system identifies itself in the MAVLink frame header.

Every MAVLink-M message that carries target_system is acknowledged, except SENSOR_TASKING, which its status response answers. The recipient answers with one final result, and may send MAVLINK_M_ACK_RECEIVED first while a human decision is pending. A message sent with target_system 0 is answered only by the systems where it selects something, with the result of applying it there, each after a short random delay so that answers on a shared channel do not collide. A system where it selects nothing, or that does not support it, does not answer, so a stop sent to every system draws one acknowledgment from each system it stops rather than one from every system on the network, and its sender expects answers only from the systems it knows hold what the stop selects. A sender with a start of its own still unacknowledged by a system also addresses the stop to that system, so that system answers it whether or not the start has arrived. Silence cannot show that a stop reached a holder its sender did not know of, so a sender that cannot rule one out repeats the stop unchanged a number of times set for the network, an answer timeout apart, and stops repeating once it issues a start the stop covers. A sender that gets no acknowledgment from a system it expects to answer sends the stop again addressed to that system, up to that number of times, and may send any other message again, unchanged, time_usec included. A receiver treats a repeat of a message it has processed (same source system and component, message ID and field values, target_system and target_component aside) as a duplicate: it does not act on it a second time, and answers it with its latest answer to that message, or with MAVLINK_M_ACK_NOT_APPLICABLE when it gave none and the repeat is addressed to it. Receivers ignore an acknowledgment sent with target_system 0.

TARGET_AUTHORIZATION (53013)

Accountability attestation for a track. Records that a specific human authority asserted positive identification, an ROE/clearance state, and no-strike context at a specific time, so the decision trail travels with the chain and is auditable after the fact.

IMPORTANT: this message is a DESCRIPTIVE RECORD, not a command. It does NOT grant authority, does NOT gate or trigger weapon release, and must not be used as an arming or engagement interlock. Release authority lives in the crewed C2 system. A receiver must never treat the presence of this message as permission to act.

SPLASH_CORRECTION (53021)

Post-impact adjustment spotting used to correct fire mission accuracy, structured per joint observed-fire doctrine (ATP 3-09.30, STANAG 1034) and the VMF K02.22 Subsequent Adjust message. The spotting is decomposed into deviation (relative to the observer-target line), range, and height-of-burst, from which a fire direction center computes corrections (e.g. bracketing, the graze "Up 40").

ENGAGEMENT_DIRECTIVE (53023)

Engagement-control directive making abort, check-fire, resume, and re-target first-class actions alongside FIRES. The ability to STOP a mission is a protocol citizen, not an afterthought. Should be paired with MAVLINK_M_ACK so the originator gets positive confirmation the directive was received and actioned.

MAVLINK_M_ENGAGEMENT_DIRECTIVE_ABORT and MAVLINK_M_ENGAGEMENT_DIRECTIVE_CHECK_FIRE are safety actions: every system they select acts on them on receipt, once message signing accepts them (see SAFETY BOUNDARIES). They do not require the authorization trail that initiating fire does.

time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
target_system	uint8_t			System ID of the intended recipient. 0 (every system) is valid only for MAVLINK_M_ENGAGEMENT_DIRECTIVE_ABORT and MAVLINK_M_ENGAGEMENT_DIRECTIVE_CHECK_FIRE; receivers ignore any other directive sent with 0.
target_component	uint8_t			Component ID of the intended recipient within target_system. 0 = every component of that system. Ignored when target_system is 0.
track_uid	uint8_t[16]			Track UID the directive applies to. All-zero if addressed by sequence only. A MAVLINK_M_ENGAGEMENT_DIRECTIVE_ABORT or MAVLINK_M_ENGAGEMENT_DIRECTIVE_CHECK_FIRE applies to every engagement that matches its sequence or its nonzero track_uid, whoever issued that engagement, and is never declined because one selector does not match. A MAVLINK_M_ENGAGEMENT_DIRECTIVE_RESUME or MAVLINK_M_ENGAGEMENT_DIRECTIVE_RETARGET applies only to an engagement that matches every selector it carries.
sequence	uint16_t			Fire mission sequence number the directive applies to. For MAVLINK_M_ENGAGEMENT_DIRECTIVE_ABORT and MAVLINK_M_ENGAGEMENT_DIRECTIVE_CHECK_FIRE, 0xFFFF means every fire mission the receiving system holds.
effector_id	uint32_t			Effector the directive is addressed to. 0 = all assigned.
retarget_lat	int32_t	degE7		New target latitude for RETARGET, WGS84. INT32_MAX = not provided (0,0 is a valid coordinate). Ignored unless directive is RETARGET.
retarget_lon	int32_t	degE7		New target longitude for RETARGET, WGS84. INT32_MAX = not provided. Ignored unless directive is RETARGET.
retarget_alt	float	m		New target altitude for RETARGET, MSL. NaN = not provided. Ignored unless directive is RETARGET.
directive	uint8_t		MAVLINK_M_ENGAGEMENT_DIRECTIVE	Directive type.
origin_sysid	uint8_t			System ID of the system that first issued the directive. A system that passes the directive on as a message of its own keeps this value, so it can differ from the source system ID in the frame header; routers never change either. Not authenticated: for display and audit, never a reason to act or not to act on the directive.

CALL_FOR_FIRE (53024)

Complete call-for-fire method elements (ATP 3-09.30 Ch.4; maps to VMF K02.4). Complements FIRES (which carries target + munition/fuze) with the warning-order, method-of-engagement, and method-of-fire-and-control elements a VMF/Link-16 packer requires. Descriptive intent only.

Field Name	Type	Units	Values	Description

ESAD_STATE (53030)

Electronic Safe and Arm Device (ESAD) telemetry for one ESAD instance on a store. Reports arming, munition, and ignition states, fault flags, and software identity. esad_id identifies the device; store_id identifies the physical bay/store.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
esad_id	uint8_t			Vehicle-local ESAD instance identifier. Must be 1-254. 0 is invalid for ESAD_STATE, 255 is reserved. A system that accepts ESAD_ARMING or ESAD_CONFIG with esad_id = 0 sets the same arming_challenge_hash on every ESAD such a command can select.
arming_challenge_hash	uint32_t			Challenge for this ESAD instance, which an ARM or an ESAD_CONFIG must carry. It ties a command to this state and is not secret.
fault_flags	uint32_t		MAVLINK_M_ESAD_FAULT_FLAGS	Active fault flag bitmask.
input_1	float			Analog/digital input 1 (implementation-defined). For the standard safety inputs use the typed fields below instead.
input_2	float			Analog/digital input 2 (implementation-defined). For the standard safety inputs use the typed fields below instead.
sw_version_hash	uint8_t[8]			Software version as 8-byte short Git hash.
arming_status	uint8_t		MAVLINK_M_ESAD_ARMING_STATUS	Current arming state.
munition_status	uint8_t		MAVLINK_M_ESAD_MUNITION_STATUS	Current munition state.
ignition_status	uint8_t		MAVLINK_M_ESAD_IGNITION_STATUS	Current ignition circuit state.
munition_type	uint8_t			Munition/store type identifier (implementation-defined).
store_id	uint8_t			Store instance identifier. Fixed physical bay assignment: a bay keeps its store_id permanently, and when a store is expended the bay may be reloaded under the same store_id. IDs never renumber. 0 = not applicable / single store. This is the canonical definition of store_id across the dialect.
pin_state	uint8_t		MAVLINK_M_ESAD_PIN_STATE	Physical safety pull-pin state (read-only status).
arm_delay_setting	uint8_t		MAVLINK_M_ESAD_ARM_DELAY_SETTING	Selected arming-delay switch position (90/60/30 s). The chosen setting.
arm_delay_remaining_s	int16_t	s		Live arming-delay countdown: seconds remaining after the in-flight-event signal until arming is permitted. -1 = not counting / not applicable. Distinct from arm_delay_setting (the switch position).
trigger_distance_mode	uint8_t		MAVLINK_M_ESAD_TRIGGER_DISTANCE_MODE	Trigger-distance standoff mode currently in effect (coarse selection, not a distance value).
track_uid	uint8_t[16]			Track UID (UUID) of the engagement this store is armed for, when applicable. Ties the armed state to a specific authorized track so a monitoring station sees "armed against track X," not merely "an ESAD is hot." All-zero if not associated with a track, and cleared to all-zero when the store is disarmed.

ESAD_ARMING (53031)

ESAD arming command for one or more ESAD instances on the receiving system. An ARM must carry the challenge the selected ESAD advertises in ESAD_STATE; with esad_id = 0 it applies only if every local ESAD selected by store_id advertises arming_challenge_hash, and is otherwise rejected, so an ARM never applies in part. A DISARM applies to every selected local ESAD without checking arming_challenge_hash, so no ESAD's state can block it; as for any stop, MAVLink message signing on the link authenticates the sender. An addressed ARM whose esad_id and store_id select no local ESAD is rejected, and an addressed DISARM that selects none is answered MAVLINK_M_ACK_NOT_APPLICABLE; a DISARM sent to every system that selects no local ESAD is not acted on or answered. Each system judges only its own ESADs, so a command that reaches several systems can apply on some and not on others; the originator confirms the result for each system from its MAVLINK_M_ACK and ESAD_STATE.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
target_system	uint8_t			System ID of the intended recipient. 0 (every system) is valid only for MAVLINK_M_ESAD_REQUEST_DISARM, which each receiving system applies to its own ESADs; receivers ignore an arm request sent with 0.
target_component	uint8_t			Component ID of the intended recipient within target_system. 0 = every component of that system. Ignored when target_system is 0.
esad_id	uint8_t			Vehicle-local ESAD instance identifier to arm or disarm. 0 = every local ESAD selected by store_id, 1-254 = specific ESAD instance, 255 = reserved.
arming_challenge_hash	uint32_t			Challenge hash the selected ESAD advertises in ESAD_STATE. Checked for an ARM, where with esad_id = 0 every selected local ESAD must advertise it; not checked for a DISARM.
arming_request	uint8_t		MAVLINK_M_ESAD_ARMING_REQUEST	Requested arming state change.
store_id	uint8_t			Target store instance identifier. 0 = every store on the receiving system.
track_uid	uint8_t[16]			Track UID (see TRACK_IDENTITY) of the engagement an ARM is for, reported back in ESAD_STATE.track_uid. All-zero if the arming is not tied to a track. Ignored for DISARM.

ESAD_CONFIG (53032)

Configuration command for an ESAD that accepts live configuration of a safe/arm parameter (e.g. a proximity device whose trigger-distance mode is set from the FMU or edge compute rather than a physical switch). Checked the same way as an ESAD_ARMING arm: arming_challenge_hash must match the value the selected ESAD last advertised in ESAD_STATE, so a command made for an older ESAD state does not apply. The hash is public, since ESAD_STATE goes to every system; MAVLink message signing on the link authenticates the sender. With esad_id = 0, store_id = 0, or both, a receiving system applies the configuration only if every local ESAD selected advertises arming_challenge_hash, and otherwise rejects it. A command that selects no local ESAD is rejected. Only coarse, device-defined SAFE/ARM modes may be set here; this message must never carry a free continuous distance, a fuze timing value, or any height-of-burst configuration. The resulting mode is reported back in ESAD_STATE.trigger_distance_mode.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
target_system	uint8_t			System ID of the intended recipient. Never 0; receivers ignore an ESAD_CONFIG sent to every system.
target_component	uint8_t			Component ID of the intended recipient within target_system. 0 = every component of that system. Ignored when target_system is 0.
arming_challenge_hash	uint32_t			Challenge hash the selected ESAD advertises in ESAD_STATE. With esad_id = 0 or store_id = 0, every selected local ESAD must advertise this hash.
esad_id	uint8_t			Vehicle-local ESAD instance identifier to configure. 0 = every local ESAD selected by store_id, 1-254 = specific ESAD instance, 255 = reserved.
store_id	uint8_t			Target store instance identifier. 0 = every store on the receiving system.
trigger_distance_mode	uint8_t		MAVLINK_M_ESAD_TRIGGER_DISTANCE_MODE	Requested coarse trigger-distance standoff mode. Coarse selection only.

STORE_STATUS (53033)

Per-store roll-up summary for release decisions. Aggregates ESAD arming state and deceleration-sensor health into a single readiness value so an operator/GCS can gate release without parsing every sensor message.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
sensor_fault_mask	uint32_t			Bitmask of MAVLINK_M_STORE_SENSOR_TYPE values currently NOT healthy (bit = 1<<sensor_type).
store_id	uint8_t			Store instance identifier.

sensors_total	uint8_t			Total count of sensors on this store.

STORE_SENSOR_STATUS (53034)

Health and current reading of one deceleration/landing-trigger sensor on a store. Emitted per sensor (one message per sensor) so the set of sensors per store can vary. A pre-release consumer aggregates these into a go/no-go decision (see STORE_STATUS).

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
value	float		invalid:NaN	Current sensor reading in the sensor's native units. NaN if invalid.
value_min	float		invalid:NaN	Lower bound of the valid operating range, native units. NaN if unspecified.
value_max	float		invalid:NaN	Upper bound of the valid operating range, native units. NaN if unspecified.
store_id	uint8_t			Store instance identifier this sensor belongs to.
sensor_type	uint8_t		MAVLINK_M_STORE_SENSOR_TYPE	Type of sensor.
sensor_index	uint8_t			Index when multiple sensors of the same type exist on a store (0-based).
health	uint8_t		MAVLINK_M_SENSOR_HEALTH	Health state of this sensor.

STORE_MUNITION (53035)

Descriptive munition inventory/status for a store, for mapping into a joint weapon-status report (e.g. at a JTAC/C2 interface). Reports WHAT is loaded so a gateway maps real data rather than synthesizing it; it does NOT carry fuze/employment configuration, which is device-internal and out of scope for this dialect. Keyed by store_id to correlate with ESAD_STATE / STORE_STATUS. Low-rate: changes on load and on release.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
mass	float	kg		Munition mass. NaN if unknown.
external_track_number	char[20]			External/joint track or store reference for gateway correlation. Empty if none.
nomenclature	char[30]			Munition nomenclature/designation (null-terminated).
quantity_remaining	uint16_t			Count of this munition remaining available on the store/carrier.
store_id	uint8_t			Store instance identifier.
munition_type	uint8_t			Munition type code (implementation-defined; consistent with ESAD_STATE.munition_type).
guidance	uint8_t		MAVLINK_M_MUNITION_GUIDANCE	Coarse guidance category.
warhead	uint8_t		MAVLINK_M_MUNITION_WARHEAD	Coarse warhead category.
arming_status	uint8_t		MAVLINK_M_ESAD_ARMING_STATUS	Safe/armed state (mirrored from ESAD for convenience).
fuze_health	uint8_t		MAVLINK_M_FUZE_HEALTH	Coarse fuze HEALTH (functioning/fault), not fuze configuration.
external_track_type	uint8_t		MAVLINK_M_TRACK_NUMBER_TYPE	Namespace of external_track_number.
munition_family	uint8_t		MAVLINK_M_MUNITION_FAMILY	Composite-munition family (finer than the warhead/guidance pair). Descriptive.

warhead_mode	uint8_t		MAVLINK_M_WARHEAD_MODE	Coarse selectable warhead MODE currently set for a selectable/multi-mode warhead (e.g. surface vs penetrate on a multi-drop magazine store). Reports the mode only. It is a COARSE enum and MUST NOT be widened to carry a fuze timing / inter-stage delay value; the actual timing is device-internal and configured on the component bus (e.g. DroneCAN) below the FMU.
sd_duration	uint8_t		MAVLINK_M_SD_DURATION	Scatterable-mine self-destruct duration CATEGORY (not exact seconds), for mine payloads.

LOITER_MUNITION_CONTROL (53036)

Loitering-munition / one-way-attack UAS control and consent handshake (JFIRE 2023). SAFETY-CRITICAL: consent_state records a MAN-IN-THE-LOOP human decision and MUST NOT be used to build an automated release path; release authority remains with the crewed C2 system. terminate provides abort/wave-off/self-destruct. Pairs with TARGET_AUTHORIZATION (record). A loitering munition also acts on ENGAGEMENT_DIRECTIVE: MAVLINK_M_ENGAGEMENT_DIRECTIVE_ABORT as MAVLINK_M_LM_TERMINATE_ABORT, and MAVLINK_M_ENGAGEMENT_DIRECTIVE_CHECK_FIRE as MAVLINK_M_LM_TERMINATE_WAVE_OFF held until a MAVLINK_M_ENGAGEMENT_DIRECTIVE_RESUME.

Both ends send it. A munition sends consent_state MAVLINK_M_LM_CONSENT_REQUESTED addressed to the human authority for the engagement: the source of the FIRES or addressed LOITER_MUNITION_CONTROL that tasked it against track_uid. It applies MAVLINK_M_LM_CONSENT_GRANTED only from that system, and every stop from any sender. consent_state and terminate carry changes, not a copy of state: a sender sets them only to make that change and otherwise sends MAVLINK_M_LM_CONSENT_NONE and MAVLINK_M_LM_TERMINATE_NONE, which leave the munition's consent and action as they are.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
target_system	uint8_t			System ID of the intended recipient: the munition, or the human authority for a consent request. 0 (every system) is valid only to stop. From a message sent with 0, a munition applies terminate MAVLINK_M_LM_TERMINATE_WAVE_OFF or MAVLINK_M_LM_TERMINATE_ABORT and consent_state MAVLINK_M_LM_CONSENT_WITHHELD or MAVLINK_M_LM_CONSENT_WITHDRAWN, treats any other terminate or consent_state value as none, and ignores the loiter station and every other field, so after an ABORT it returns to the loiter station it already holds. It never drops the stop because the message carries something else. Receivers ignore a LOITER_MUNITION_CONTROL sent with 0 that carries no stop.
target_component	uint8_t			Component ID of the intended recipient within target_system. 0 = every component of that system. Ignored when target_system is 0.
track_uid	uint8_t[16]			128-bit track UID of the engaged object (see TRACK_IDENTITY).
consent_state	uint8_t		MAVLINK_M_LM_CONSENT_STATE	Man-in-the-loop consent-to-strike state (recorded human decision, not a trigger).
terminate	uint8_t		MAVLINK_M_LM_TERMINATE	Abort / wave-off / self-destruct action.
tst_status	uint8_t		MAVLINK_M_TST_STATUS	Time-sensitive-target prosecution status.
pid_status	uint8_t		MAVLINK_M_PID_STATUS	Positive-identification status gate (from TRACK_IDENTITY set).
cde_level	uint8_t		MAVLINK_M_CDE_LEVEL	Collateral-damage-estimate level gate (number only).
loiter_lat	int32_t	degE7		Loiter/orbit station latitude, WGS84. INT32_MAX = not provided (0 is a valid coordinate).
loiter_lon	int32_t	degE7		Loiter/orbit station longitude, WGS84. INT32_MAX = not provided (0 is a valid coordinate).
dmpi_kind	uint8_t		MAVLINK_M_DMPI_REFERENCE_KIND	How the desired point of impact is referenced (no mensurated coordinate).

weapon_string	char[50]			Human-readable weapon description or designation (null-terminated).
arming_state	uint8_t		MAVLINK_M_RWS_ARMING_STATE	Current arming state of the weapon system.
weapon_type	uint8_t			Weapon type identifier (implementation-defined).

SENSOR_TASKING (53050)

Inbound sensor/payload tasking from a UCI C2 node, and the platform's tasking-status response. Provided for gateway mapping between UCI publish/subscribe events and native MAVLink payload control; it does not replace MAVLink platform control. Carries commanded sensor mode and an optional point of interest or track to slew to.

A request carries status MAVLINK_M_TASKING_UNSPECIFIED and is addressed to the sensor or payload. A status response carries any other status and is addressed to the requester: the source system and component IDs in the request's frame header. A response echoes task_id and track_uid and reports the mode in effect in sensor_mode; receivers ignore its point-of-interest fields. When a task ends for any reason other than its requester's own request, the sensor sends that requester a status response with MAVLINK_M_TASKING_INTERRUPTED, echoing the task's task_id and track_uid. Status responses go only to the requester.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
target_system	uint8_t			System ID of the intended recipient: the sensor's system for a request, the requester's for a status response. Never 0, not even to cage every sensor: a STANDBY sent to every system would also cage a designator guiding a weapon already in flight. Receivers ignore a SENSOR_TASKING sent with 0.
target_component	uint8_t			Component ID of the intended recipient within target_system: the sensor or payload for a request, the requester for a status response. 0 = every component of that system. Ignored when target_system is 0.
task_id	uint16_t			Tasking correlation id, chosen by the requester and echoed unchanged in every status response for that task. A sensor tells tasks apart by the requester's system and component IDs together with task_id.
sensor_mode	uint8_t		MAVLINK_M_SENSOR_MODE	Commanded sensor/payload mode in a request; the mode in effect in a status response.
status	uint8_t		MAVLINK_M_TASKING_STATUS	MAVLINK_M_TASKING_UNSPECIFIED in a request, any other value in a status response; this is how a receiver tells the two apart.
poi_lat	int32_t	degE7		Point-of-interest latitude to slew to, WGS84. INT32_MAX = not provided (0 is a valid coordinate).
poi_lon	int32_t	degE7		Point-of-interest longitude to slew to, WGS84. INT32_MAX = not provided (0 is a valid coordinate).
poi_alt	float	m		Point-of-interest altitude, MSL. NaN = not provided.
track_uid	uint8_t[16]			Track UID (see TRACK_IDENTITY) the sensor is to follow. When set, the sensor follows that track and the point of interest is only a starting cue; with sensor_mode MAVLINK_M_SENSOR_MODE_LASER_DESIGNATE or MAVLINK_M_SENSOR_MODE_IR_MARK the track only cues the sensor, which lases or marks what its own tracker holds. All-zero to point at the point of interest.

CAS_9LINE (53060)

Close air support 9-line brief (JP 3-09.3 / JFIRE). Descriptive tasking data classes for a CAS attack. Laser code is carried as a slot, never a value. Danger close is a flag; RED tables are never embedded.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
target_system	uint8_t			System ID of the intended recipient: the attacking aircraft. A flight gets the brief addressed to each of its aircraft. Never 0; receivers ignore a 9-line sent to every system.
target_component	uint8_t			Component ID of the intended recipient within target_system. 0 = every component of that system. Ignored when target_system is 0.
sequence	uint16_t			Engagement sequence of this brief, chosen by its sender. TERMINAL_CONTROL.sequence refers to it. 0xFFFF is reserved: in a stop it means every brief.

tgt_lat	int32_t	degE7		Line 6: target latitude, WGS84.
tgt_lon	int32_t	degE7		Line 6: target longitude, WGS84.
mark_type	uint8_t		MAVLINK_M_MARK_TYPE	Line 7: type of mark / terminal guidance.
laser_code_slot	uint8_t			Line 7: 1 = a laser code is assigned (slot); 0 = none. Never the numeric code.
friendlies_lat	int32_t	degE7		Line 8: friendlies latitude, WGS84.
friendlies_lon	int32_t	degE7		Line 8: friendlies longitude, WGS84.
egress_deg	uint16_t	deg		Line 9: egress heading.
final_attack_heading_deg	uint16_t	deg		Remarks: final attack heading (FAH). 0xFFFF if unspecified.
danger_close	uint8_t			Remarks: 1 = danger close / troops in contact; 0 = not.
delivery	uint8_t		MAVLINK_M_ORDNANCE_DELIVERY	Bomb-on-coordinate vs bomb-on-target.
track_uid	uint8_t[16]			Track UID (see TRACK_IDENTITY) of the target this brief describes. All-zero if not associated with a track.

TERMINAL_CONTROL (53061)

Terminal-attack-control handshake (JP 3-09.3). Carries the control type, the clearance or abort verb, and attacking-aircraft status calls. Both ends send it. The controller sends clearance, addressed to the attacking aircraft, with aircraft_call MAVLINK_M_ACFT_CALL_NONE. The aircraft sends aircraft_call, addressed to the controller (the source of the CAS_9LINE with this sequence), with clearance MAVLINK_M_CAS_NONE, so a report is never read as a clearance or an abort. MAVLINK_M_CAS_CONTINUE and MAVLINK_M_CAS_CLEARED_HOT are human-authority instruments: they record a human decision, must not be wired as an automated release path, and are acted on only from the controller that sent the brief. MAVLINK_M_CAS_ABORT and MAVLINK_M_CAS_CEASE_FIRE are safety actions: the aircraft acts on them on receipt from any sender, whatever tac_type and abort_authority_present say.

Field Name	Type	Units	Values	Description
time_usec	uint64_t	us		Timestamp (UNIX epoch, microseconds UTC).
target_system	uint8_t			System ID of the intended recipient: the attacking aircraft for a clearance, the controller for an aircraft call. 0 (every system) is valid only with clearance MAVLINK_M_CAS_ABORT or MAVLINK_M_CAS_CEASE_FIRE, and a receiver acts only on that clearance in such a message; receivers ignore any other TERMINAL_CONTROL sent with 0.
target_component	uint8_t			Component ID of the intended recipient within target_system. 0 = every component of that system. Ignored when target_system is 0.
sequence	uint16_t			Engagement sequence this handshake applies to: the CAS_9LINE.sequence of the brief it controls. With clearance MAVLINK_M_CAS_ABORT or MAVLINK_M_CAS_CEASE_FIRE, 0xFFFF means every attack the receiving aircraft is making.
tac_type	uint8_t		MAVLINK_M_TAC_TYPE	Type of terminal attack control (1/2/3).
clearance	uint8_t		MAVLINK_M_CAS_CLEARANCE	Clearance / abort verb (human authority).
aircraft_call	uint8_t		MAVLINK_M_AIRCRAFT_CALL	Attacking-aircraft status call.
abort_authority_present	uint8_t			1 = a valid abort authority is established for this engagement; 0 = not. A precondition for MAVLINK_M_CAS_CLEARED_HOT; it never gates MAVLINK_M_CAS_ABORT or MAVLINK_M_CAS_CEASE_FIRE.

5	MAVLINK_M_ACK_EXPIRED	Message was received after its validity window had passed: a start (SAFETY BOUNDARIES) whose time_usec is older than the maximum age the receiving system is configured with. A stop is never rejected for its time.
6	MAVLINK_M_ACK_NOT_APPLICABLE	Message was addressed to this system, and nothing on this system is what it applies to, for example a stop for an engagement this system does not hold. A final result. Never sent in answer to a message sent to every system: a system where such a message selects nothing does not answer it.
7	MAVLINK_M_ACK_HELD	A start (SAFETY BOUNDARIES) was not applied because it may have been issued before a stop the receiving system recorded and that covers it, or before the system restarted. It may be the start the stop was sent to prevent, so it is issued again, with a new time_usec, only as a new decision of its authority, never automatically. A final result.

Commanded/reported sensor payload mode (UCI-style tasking).

Value	Name	Description
0	MAVLINK_M_SENSOR_MODE_UNKNOWN	Unspecified.
1	MAVLINK_M_SENSOR_MODE_WIDE_AREA_SEARCH	Wide-area search.
2	MAVLINK_M_SENSOR_MODE_POINT_TRACK	Point-target track.
3	MAVLINK_M_SENSOR_MODE_LASER_DESIGNATE	Laser designation (code carried as slot elsewhere, not a value).
4	MAVLINK_M_SENSOR_MODE_LASER_RANGE	Laser ranging.
5	MAVLINK_M_SENSOR_MODE_IR_MARK	IR pointer / mark.
6	MAVLINK_M_SENSOR_MODE_STANDBY	Sensor standby / caged.

MAVLINK_M_TASKING_STATUS

Response to an inbound tasking request (UCI publish/subscribe event).

Value	Name	Description
0	MAVLINK_M_TASKING_UNSPECIFIED	Marks a SENSOR_TASKING request; a status response never carries it. Not an acceptance.
1	MAVLINK_M_TASKING_ACK	Tasking accepted.
2	MAVLINK_M_TASKING_REJECTED	Tasking rejected (unable/ineligible).
3	MAVLINK_M_TASKING_COMPLETE	Tasking complete.
4	MAVLINK_M_TASKING_ACTIVE	Tasking in progress.
5	MAVLINK_M_TASKING_INTERRUPTED	Tasking ended before completion for a reason its requester did not cause: another request took the sensor, or the sensor lost the track it was following. Sent to the requester of the interrupted task.

Commands (MAV_CMD)

MAV_CMD_MAVLINK_M_STORE_ARM (53090)

Safe a store's ESAD. A command carries no time_usec, so no stop can be ordered against an arm sent this way (SAFETY BOUNDARIES): receivers answer an arm (Arm = 1) with MAV_RESULT_DENIED, and ESAD_ARMING arms.

Param (Label)	Description
1 (Store ID)	Target store instance (0 = every store on the receiving system).
2 (Arm)	0 = safe/disarm. 1 = arm, which receivers deny; arm with ESAD_ARMING.
3 (Challenge Hash)	Ignored: a safe applies whatever the ESAD challenge holds, as an ESAD_ARMING DISARM does.
4	Reserved (0).
5	Reserved (0).
6	Reserved (0).
7	Reserved (0).

MAV_CMD_MAVLINK_M_STORE_RUN_BIT (53091)

Run a built-in self-test (BIT) on a store. Never sent with target_system 0; receivers ignore one that is.

Param (Label)	Description
1 (Store ID)	Target store instance (0 = every store on the receiving system).
2 (Scope)	0 = full BIT, 1 = sensors only, 2 = ESAD only.
3	Reserved (0).
4	Reserved (0).
5	Reserved (0).
6	Reserved (0).
7	Reserved (0).

MAV_CMD_MAVLINK_M_STORE_REQUEST_STATUS (53092)

Request status push from a store.

Param (Label)	Description
1 (Store ID)	Target store instance (0 = every store on the receiving system).
2 (What)	0 = STORE_STATUS only, 1 = all STORE_SENSOR_STATUS, 2 = both.
3	Reserved (0).
4	Reserved (0).
5	Reserved (0).
6	Reserved (0).
7	Reserved (0).

MAV_CMD_MAVLINK_M_STORE_SET_DECEL_THRESHOLD (53093)

Set the deceleration/landing-system trigger threshold for a store. Never sent with target_system 0; receivers ignore one that is.

Param (Label)	Description
1 (Store ID)	Target store instance (0 = every store on the receiving system).
2 (Sensor Type)	Sensor (MAVLINK_M_STORE_SENSOR_TYPE) that gates deployment.
3 (Threshold)	Threshold value in the sensor's native units.
4 (Direction)	0 = trigger when reading falls below threshold, 1 = trigger when reading rises above threshold.
5	Reserved (0).
6	Reserved (0).
7	Reserved (0).
