A method for monitoring an integrity of reference stations of a correction service system, correction service system, method for operating a satellite-based navigation system and satellite-based navigation system

摘要

The invention relates to a method for monitoring an integrity of known and fixed coordinates reference stations (1.1, 1.2,1.3, ..., 1.n) of a correction service system (12) for a satellite-based navigation system (25) in a coordinate system, wherein at least one first group (2) of the reference stations (1.1, 2.1, 1.3, ..., 1.n) is operated to receive satellite signals from a plurality of satellites of the satellite-based navigation system (25). It is provided that a) a first reference station (1.2.3) from the first group (2) is selected, wherein b) in dependence on the other reference stations (1.1,1.3, ..., 1.n) of the first Group (2) each received satellite signals and the known coordinates of the respective other reference station (1.1,1.3, ..., 1.n) of the first group (2) at least a first correction value (23) is determined (4), and wherein c ), the integrity monitoring is carried out by determining first coordinates of the first reference station (1.2, 3), which are determined (5) by means of the satellite signals received by the first reference station (1.2, 3) and the at least one first correction value (23) the known coordinates of the first reference station (1.2,3) are compared and checked for at least a first deviation (6).
