METHOD FOR DETERMINING USER COORDINATE SYSTEMS GLONASS / GPS AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: radio engineering, communication.;SUBSTANCE: method involves receiving signals from navigation spacecraft, amplification and correction thereof, monitoring codes and frequencies, calculating pseudoranges and pseudovelocities, correcting ionosphere errors and calculating coordinates of the consumer. The value of the ionosphere adjustment is determined by an empirical model of the required ionosphere parameter based on known parameters (geographic coordinates and time) and an additional parameter - solar activity index with one-time processing of the array of values of vertical PES in the ionosphere. Corresponding numerical values are selected from arrays of values of vertical PES, provided by different centres, followed by compression, filtration of the obtained array and forming an input numerical data array for subsequent calculation of ionosphere adjustments and absolute values of coordinates of the consumer. During one-time processing of the array of values of vertical PES in the ionosphere, input data from IONEX files are used to form a PES mode.;EFFECT: high accuracy of determining coordinates of a consumer by eliminating ionosphere errors.;4 cl, 5 dwg
