number
Meaning: Continue, enum MAV_GOTO; maps to MAVLink parameter 1 in the PX4 frame.
​
payload.position
number
Meaning: Position, enum MAV_GOTO; maps to MAVLink parameter 2 in the PX4 frame.
​
payload.frame
number
Meaning: Frame, enum MAV_FRAME; maps to MAVLink parameter 3 in the PX4 frame.
​
payload.yaw
number
Meaning: Yaw, units deg; maps to MAVLink parameter 4 in the PX4 frame.
​
payload.latitude_x
number
Meaning: Latitude/X; maps to MAVLink parameter 5 in the PX4 frame.
​
payload.longitude_y
number
Meaning: Longitude/Y; maps to MAVLink parameter 6 in the PX4 frame.

PX4 Frame Mapping

  • MAVLink command: MAV_CMD_OVERRIDE_GOTO
  • Command ID: 252
  • Default transport: COMMAND_INT
  • Source XML: common.xml
  • Completion: COMMAND_ACK
  • Guard: real PX4 downlink is disabled by default; guarded mode requires explicit authorization and a ready transport.

PX4 ACK Mapping

After sending the frame, the PX4 agent waits for COMMAND_ACK and correlates the response by command id. Disabled mode sends no frame and completes with a rejected lifecycle result.
