VehicleAirData (повідомлення UORB)

Vehicle air data.

Data from the currently selected barometer (plus ambient temperature from the source specified in temperature_source). Includes calculated data such as barometric altitude and air density.

TOPICS: vehicle_air_data

Fields

Назва	Тип	Unit [Frame]	Range/Enum	Опис
timestamp	uint64	us		Time since system start
timestamp_sample	uint64	us		Timestamp of the raw data
baro_device_id	uint32			Unique device ID for the selected barometer
baro_alt_meter	float32	m [MSL]		Altitude above MSL calculated from temperature compensated baro sensor data using an ISA corrected for sea level pressure SENS_BARO_QNH
