Fields

Field	Type	Units	Enum	Description	Default	Extension
time_usec	uint64_t	us	—	Timestamp (UNIX epoch time or time since system boot). The receiver can infer the format (since 1.1.1970 or since boot) by the magnitude.	—	No
target_num	uint8_t	—	—	ID of the target if multiple targets are present.	—	No
frame	uint8_t	—	MAV_FRAME	Coordinate frame used for following fields.	—	No
angle_x	float	rad	—	X-axis angular offset of the target from the center of the image.	—	No
angle_y	float	rad	—	Y-axis angular offset of the target from the center of the image.	—	No
distance	float	m	—	Distance to the target from the vehicle.	—	No
size_x	float	rad	—	Size of target along x-axis.	—	No
size_y	float	rad	—	Size of target along y-axis.	—	No
x	float	m	—	X position of the landing target in MAV_FRAME.	—	Yes
y	float	m	—	Y position of the landing target in MAV_FRAME.	—	Yes
z	float	m	—	Z position of the landing target in MAV_FRAME.	—	Yes
q	float[4]	—	—	Quaternion of landing target orientation in order (w, x, y, z). Zero-rotation is 1, 0, 0, 0.	—	Yes
type	uint8_t	—	LANDING_TARGET_TYPE	Type of landing target.	—	Yes
position_valid	uint8_t	—	MAV_BOOL	Position fields (x, y, z, q, type) contain valid target position information (MAV_BOOL_FALSE: invalid). Values not equal to 0 or 1 are invalid.	0	Yes
