GEOMETRIC FACTOR AND ITS INFLUENCE ON NAVIGATION PARAMETERS DETERMINING ERROR IN PSEUDOSATELLITE RADIO SYSTEM

Abstract

TIt is proved that the relation between errors definition of primary and secondary navigation parameters depends on the type of matrix consumer gradients (C), that is, the geometry of the mutual position of pseudosatellites (PS) and the consumer C. The analysis showed that in the general expression for the geometrical factor (MS) can be written as the ratio of GDOR = = σq/σD, where σq – mean square error (MSE) of the consumer C state vector definition; σD – MSE to determine pseudorange to PS. It is determined that the practice of consumers interested in the degree of deterioration in the accuracy of positioning separate horizontal and vertical planes relative to the Earth's surface, as well as the degree of time corrections determining accuracy deterioration.
