Embodiment Construction

[0037] figure 1 An exemplary diagrammatic view of providing GNSS correction data 1 according to the prior art is schematically shown. Three GNSS satellites 7 of different constellations are shown, a correction data provider 4 receiving the signals of the GNSS satellites 7 - which receives the signals at a known geodetic position - and a mobile GNSS receiver 6 also receiving the signals of the GNSS satellites 7 . The correction data provider 4 determines the GNSS correction data 1 from the received signals, eg by comparison with known geodetic positions.

[0038] Furthermore, the correction data provider 4 determines, for example, the integrity information associated with the GNSS correction data 1 provided by it, and thereby forms the integrity data 5 . Here, the correction data provider 4 provides the GNSS correction data 1 to the GNSS receiver 6 in combination with the associated integrity data 5 . Thus, a GNSS receiver 6 , which may for example be a GNSS receiver 6 of an...

Abstract

The invention relates to a method for checking the integrity of GNSS correction data (1), comprising at least the following steps: a) receiving provided GNSS correction data (1) without relevant integrity information; b) receiving reference data (2) which allows the integrity of the GNSS correction data (1) received in step a) to be inferred; c) checking the integrity of the GNSS correction data (1) received in step a) using the reference data (2) received in step b).

Description

technical field [0001] The present invention relates to a method for integrity checking of GNSS correction data, a method for providing integrity data, a method for providing GNSS correction data, a computer program and a machine readable storage medium. The present invention is particularly useful in connection with autonomous driving. In addition, the present invention can also be used for other safety-related applications in the field of satellite positioning. Background technique [0002] In the case of GNSS (Global Navigation Satellite System) navigation, GNSS correction data are generally used, which are used to take into account determinable errors of the GNSS signals when positioning. The determinable error may be, for example, the propagation time error of the GNSS signal. This propagation time error can be determined, for example, by receiving GNSS signals with a reference station, the geodetic position of which is precisely known. Here, the correction can be d...
