METHOD AND DEVICE FOR DETECTING A GROUP RUNTIME VARIATION FOR A NAVIGATION SENSOR FOR A NAVIGATION SYSTEM FOR A VEHICLE AND NAVIGATION SENSOR WITH A DEVICE OF THIS KIND

摘要

The approach presented here relates to a method for detecting a group runtime variation (102) for a navigation sensor (105) for a navigation system (110) for a vehicle (115). The method comprises a step of reading and a step of determining. In the reading step, at least one first GNSS simulator signal (127) is read from a virtual satellite (130) of a virtual global navigation satellite system (135) at a first time and a second GNSS simulator signal (140) is read from the virtual satellite (130) or from at least one second virtual satellite (145) of the virtual navigation satellite system (135) at a second time different to the first time by means of a read device (120). The group runtime variation (102) is determined using the first GNSS simulator signal (127) and the second GNSS simulator signal (140) in the determining step.
