Abstract :
An exploratory development model of an optimally integrated system for Artic land navigation has been designed, implemented, and tested. This system, called PLANS (Primary Land Arctic Navigation System) was designed and built to be a highly reliable, moderately accurate and moderately priced, nonradiating automatic navigation system for all-weather off-the-road use. It combines several self-contained sensors with two satellite receivers, using an eight-state Kalman filter on a microcomputer, to provide a continuous optimal estimate of position, heading and speed. The self-contained sensors consist of a strapdown gyro unit, an odometer pickoff for speed, a magnetic fluxgate sensor, and a baroaltimeter. The satellite receivers are a C/A code GPS (Global Positioning System) and dual-channel transit receiver
