Embodiment Construction
[0025] figure 1 A schematic diagram showing an embodiment of an advantageous method for monitoring the integrity of reference stations 1.1, 1.2, 1.3, ..., 1.n of a correction service system for a satellite-aided navigation system in a coordinate system, said reference stations With known and fixed coordinates, at least one first group 2 of reference stations 1.1, 1.2, 1.3, ..., 1.n are operated to receive satellite signals of a plurality of satellites of a satellite-aided navigation system. This advantageous method is characterized in that, in step a), a first reference station 3 is selected from said first group 2 . The first reference station 3 corresponds to the reference station 1 . 2 in the exemplary embodiment of the advantageous method shown here. Next, in step b) (in figure 1shown by reference numeral 4) according to the satellite signals respectively received by the remaining reference stations 1.1, 1.3, ..., 1.n of said first group 2 and the corresponding remaining...

The invention relates to a method for monitoring an integrity of reference stations (1.1, 1.2, 1.3,...,1.n) of a correction service system (12) for a satellite-assisted navigation system (25) that have known and fixed coordinates in a coordinate system, wherein at least one first group (2) of the reference stations (1.1, 1.2, 1.3,... ,1.n) is operated in order to receive satellite signals from multiple satellites of the satellite-assisted navigation system (25). In this case, there is provision for a) a first reference station (1.2,3) to be selected from the first group (2), wherein b) the satellite signals each received by the other reference stations (1.1, 1.3,..., 1.n) of the first group (2) and the known coordinates of the respective other reference station (1.1, 1.3,..., 1.n) of the first group (2) are taken as a basis for ascertaining (4) at least one first correction value (23), and wherein c) the monitoring of the integrity is performed by virtue of 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), being compared with the known coordinates of the first reference station (1.2,3) and checked for at least one first disparity (6).
Description
technical field [0001] The invention relates to a method for monitoring the integrity of a reference station of a correction service system and a correction service system. The invention also relates to a method for operating a satellite-aided navigation system and a satellite-aided navigation system. Background technique [0002] Global Navigation Satellite System (GNSS) enables determination of the position of user equipment, such as a navigation system, in a coordinate system. In this case, the propagation times of the received satellite signals of the satellites of the global navigation satellite system are ascertained with such a user device, and the distance between the respective satellite and the user device is derived therefrom. The speed of light is often assumed to be the speed at which satellite signals travel. If disturbances occur during the transmission, for example due to certain conditions in the ionosphere or troposphere, in particular propagation time va...
