Abstract : The patent relates to a system using a pendulous, integrating, gyroscope accelerometer rotated about its gravity axis, in a level plane on the earth. The rotation velocity of the earth causes the pendulous mass to exert a varying precessional force on the gyroscope. The force is detected and correlated with the angular position of the accelerometer to determine north.
