Pressure based reference system for aircraft attitude measurement

• The measurement system can provide Euler angles reference. • Different methods of correcting measured values were introduced and tested: • The method based on subtracting pressure drift with accelerometer: • Provides the best results in static measurement. • Designed for system with two reference volumes. • The method based on calculating pressure difference from accelerometer: • Would provide best results in an UL airplane. • Can be used in booth versions of the reference system. • Results from measurement in a wind tunnel proves usability. • Future work: • Include magnetometer, • Test measurement in an UL aircraft.
