GPS/Doppler Sensor Velocity Derived Attitude Reference System.

Abstract

An accurate and constantly updated attitude instrument is provided for aircraft. The pitch and roll angles are calculated from two sets of velocity measurements, one set being derived from signals received from orbiting navigational satellites and the other set from on-board equipment which determines the aircraft's axial velocities. The on-board equipment may be a Doppler ground-speed sensor or an inertial system using accelerometers, the outputs of which are integrated to derive the axial velocities. (Author)
