TOPICS: follow_target_estimator

Fields

Name	Type	Unit [Frame]	Range/Enum	Description
timestamp	uint64			time since system start (microseconds)
last_filter_reset_timestamp	uint64			time of last filter reset (microseconds)
valid	bool			True if estimator states are okay to be used
stale	bool			True if estimator stopped receiving follow_target messages for some time. The estimate can still be valid, though it might be inaccurate.
lat_est	float64			Estimated target latitude
lon_est	float64			Estimated target longitude
alt_est	float32			Estimated target altitude
pos_est	float32[3]			Estimated target NED position (m)
vel_est	float32[3]			Estimated target NED velocity (m/s)
acc_est	float32[3]			Estimated target NED acceleration (m^2/s)
prediction_count	uint64
fusion_count	uint64
