ABSTRACT:
A device is provided for enabling inertial land navigation of a vehicle, for measuring and updating vehicle heading by North-seeking and navigating. A single dual-axis gyroscope is sequenced through North-seeking, parameter calibration, and navigating by a high resolution flip table rotated by a stepper motor, without a gimballed support therefor. Inclinometers aid the gyroscope in North-seeking and parameter calibration without accelerometers therefor.
