TOPICS: airspeed_validatedv0

Fields

Name	Type	Unit [Frame]	Range/Enum	Description
timestamp	uint64			time since system start (microseconds)
indicated_airspeed_m_s	float32			indicated airspeed in m/s (IAS), set to NAN if invalid
calibrated_airspeed_m_s	float32			calibrated airspeed in m/s (CAS, accounts for instrumentation errors), set to NAN if invalid
true_airspeed_m_s	float32			true filtered airspeed in m/s (TAS), set to NAN if invalid
calibrated_ground_minus_wind_m_s	float32			CAS calculated from groundspeed - windspeed, where windspeed is estimated based on a zero-sideslip assumption, set to NAN if invalid
true_ground_minus_wind_m_s	float32			TAS calculated from groundspeed - windspeed, where windspeed is estimated based on a zero-sideslip assumption, set to NAN if invalid
airspeed_sensor_measurement_valid	bool			True if data from at least one airspeed sensor is declared valid.
selected_airspeed_index	int8			1-3: airspeed sensor index, 0: groundspeed-windspeed, -1: airspeed invalid
airspeed_derivative_filtered	float32			filtered indicated airspeed derivative [m/s/s]
throttle_filtered	float32			filtered fixed-wing throttle [-]
pitch_filtered	float32			filtered pitch [rad]
