GPS/GLONASS INTEGRATION WITH ALTIMETER AND COMPASS IN THE NAVIGATION SYSTEMS OF LAND MOBILE VEHICLES

摘要

We consider the possibility of using electronic pickups of barometric gauging of an altitude and horizontal direction in the capacity of back-up devices for the purposes of a positioning of land moving objects in conditions of bad visibly of satellites. The nonlinear simultaneous equations of the solution of a navigation task by results of measurements of an altitude and three pseudoranges, and an altitude, an azimuth and two pseudoranges are adduced. The iterative method of the solution of the obtained simultaneous equations is offered and initial values for the given method are determined. The algorithm of the solution of navigation task information from an altimeter and a compass using at insufficient volume of satellite measurements is formed in a general view.
