A method for checking the plausibility of GNSS position signals

The invention relates to different methods for checking the plausibility of GNSS position signals, including a method for checking the plausibility of position signals (112, 14f) of a global navigation satellite system (100) in a vehicle (1), the (at least one detection system (2) for detecting objects 64, 66, 70, 72, 67) (in the surroundings of the vehicle 1) and a receiving means (10) for receiving the position signals (112, 14f) includes, comprising the steps of: - receiving the position signals (112, 14f) by means of the receiving means (10) and determining the own position of the vehicle (1) on the basis of the position signals (112, 14f), - detecting at least one object (64, 66, 70, 72, 67) in the environment by means of the detection system (2) and determining the position of the object (64, 66, 70, 72, 67), - checking the plausibility of the position signals (112, 14f) by adjusting at least a position of an object (64, 66, 70, 72, 67) with the natural position of the vehicle (1).
