Airspeed (UORB message)

Airspeed data from sensors.

This is published by airspeed sensor drivers, CAN airspeed sensors, simulators. It is subscribed by the airspeed selector module, which validates the data from multiple sensors and passes on a single estimation to the EKF, controllers and telemetry providers.

TOPICS: airspeed
