METHOD FOR MONITORING AN INTEGRITY OF REFERENCE STATIONS OF A CORRECTION SERVICE SYSTEM, CORRECTION SERVICE SYSTEM, METHOD FOR OPERATING A SATELLITE-ASSISTED NAVIGATION SYSTEM AND SATELLITE-ASSISTED NAVIGATION SYSTEM

摘要

A method for monitoring an integrity of reference stations, having known and fixed coordinates, of a correction service system for a satellite-supported navigation system. A first group of the reference stations is operated to receive satellite signals of a plurality of satellites of the satellite-supported navigation system. It is provided that a) a first reference station is selected from the first group, and b) at least one first correction value is ascertained as a function of the satellite signals respectively received by the remaining reference stations of the first group, and c) the monitoring of the integrity is carried out in that first coordinates of the first reference station, determined using the satellite signals received by the first reference station and using the at least one first correction value, are compared with the known coordinates of the first reference station and checked for at least one first deviation.
