摘要
The method indicates a way to avoid or considerably reduce the possibility of a jamming or spoofing attack successfully affecting the signals from the satellites, allowing the satellites to be detected even in situations where the receiver is starting up cold and makes it possible for the GNSS positions that have been verified using same to be accepted as evidence before a court of law. To ensure that the position calculated by the receiver is valid, the method includes a transmitter in the radio navigation receiver, various functions added to the actual satellites and the ground control segment of the GNSS system, in order to be able to calculate the location/area where the receiver is located. With the information, the position supplied by the receiver can be compared with that calculated by a third entity to detect whether it is correct or, conversely, if it cannot be considered valid.
