In many drone applications the airspeed is important information for reliable and controlled take off, landing and flight. The airspeed is most effectively measured with a pilot tube and a differential pressure sensor. Recently, PX4 integrated the SDP3x differential pressure sensor into an airspeed sensor development kit for VTOL and fixed wing UAV applications, which is fully integrated with the open source autopilot. The integration includes a full aerodynamic software compensation model for the sensor and pitot tube making it a plug and play solution.
