METHOD OF IMPROVING INTEGRITY OF USED NAVIGATION SATELLITE SIGNALS USING LOCAL MONITORING AND CORRECTION STATION (LMCS) BASED ON ANOMALOUS IONOSPHERIC EFFECT

摘要

FIELD: radio engineering, communication.;SUBSTANCE: ground-based stationary local monitoring and corrections station (LMCS), having accurately predetermined coordinates of dislocation thereof, receives and processes radio signals of a group of radio-visible navigation satellites of active global navigation satellite systems using an antenna module, a satellite navigation receiver unit and a computer. The method employs additional self-contained equipment, having accurately predetermined coordinates of dislocation thereof and having an antenna module and a satellite navigation receiver unit for receiving and processing radio signals from navigation satellites, used for phase measurement of received radio signals of navigation satellites; simultaneously received radio signals from standard navigation satellites are processed independently of each other at receivers of their satellite navigation receiver unit such that, knowing the frequency and phase of radiation of radio transmissions of a specific navigation satellite and knowing the distance between the LMCS and self-contained equipment, the error of the effect of the ionosphere on the pseudo-range value is determined in length measurement units from measurements of full phases at spaced-apart satellite navigation receiver units, for which the full phase value from the self-contained equipment is transmitted over the corresponding channel to the LMCS computer, where the error of the effect of the ionosphere on at the present moment is finally determined.;EFFECT: providing detection and calculation of the error of the effect of the ionosphere on pseudo-range codes.;7 cl, 1 dwg
