xADU

Air-Data Unit

The xADU is S-PLANE’s modular extension to the xFCU, allowing for remote air-data measurement and digitisation. This architecture minimises pneumatic tubing and associated errors/lag and is ideal for larger Tactical and Strategic class UAVs and OPVs. The xADU provides airspeed (IAS, TAS, Mach No.), altitude (barometric, density), climb rate (VSI) and air-data (humidity, OAT, air density) measurements at up to 50 Hz via a serial interface.
