Abstract

A navigational instrument for land, air or sea vehicles which comprises inertial measuring means 16 including sensors (e.g. a two-axis gyro 20 and a rotary accelerometer 32) which respond to rotary movements of the vehicle about vehicle-fixed axes and accelerometers 28, 30 which respond to linear accelerations; and which further comprises velocity sensors 12, 14 (e.g. a Doppler radar or a sonar log) for sensing the velocity of the vehicle over the ground; in which inertial measuring signals are used to compute parameters 60 for transforming the vector components from the vehicle-fixed coordinate system into an earth-fixed system; the translation acceleration is computed 74,76 depending upon the gravity components of acceleration; the translation acceleration is integrated 78, 80 to determine the inertial velocity; the velocity is optimized 82; transformed velocity values referred to an earth- fixed coordinate system are computed 94 from the optimised velocity values and the transformation parameters; and the position of the vehicle is computed 96 from the transformed velocity values. <IMAGE>
