Title: Satellite signal receiver with speed computing integrity control

Abstract: A satellite positioning receiver with velocity calculation integrity check. In order to increase the reliability of the velocity measurements by the receiver, it is proposed to measure the divergence between the measurements taken on n satellite director axes (n>4) and to given an alarm if this divergence exceeds a predetermined threshold. The divergence is measured by the mean square error between the calculated velocity vector and the velocities as measured along the director axes and projected on to the calculated velocity vector.
