Design of an Optimally Integrated Primary Land Arctic Navigation System. (Plas). Volume 1. System Design,

Abstract

This land navigation system is designed around a dual mode gyrocompass/directional gyro, and the vehicle's odometer, with occasional Transit position fixes. A baroaltimeter is used to provide height above ellipsoid needed by the Transit receiver, and a coarse digital elevation map is used to bound the error in the barometric height. An inexpensive magnetic flux valve is used, in conjunction with a geomagnetic field model, to augment the gyro and provide a rough initial heading. An eight state extended Kalman Filter was designed to process the measurements from these sensors and thus provide an optimal estimate of the vehicles position, velocity and bearing.
