摘要： A system and method are described for mitigating the jamming or spoofing of information that is used in a Global Navigation Satellite System (GNSS) geolocation system, such as the Global Positioning System (GPS). In an area of interest where accurate geolocation information is critical—for example, at an airport, harbour, or other locations where accurate navigation is critical—several receiving stations having known and pre-determined geolocations are positioned. These receiving stations receive location signals from a constellation of geolocation satellites, and send the information about received signals to a central processing hub. The processing hub includes facilities to compare location information received by a particular receiving station and to determine whether the location information received by that receiving station from a particular satellite is consistent with known location information about that receiving station. In the event that there is a discrepancy—as measured by filters designed to identify signals outside set thresholds—between the known location information and the received location information, the processing hub can send a warning signal that the location information from a satellite whose location information is found outside of thresholds should be ignored and that other positioning information should be used. The system and method may also be adapted to allow overriding of incorrect or undetectable location information with correct information so that an end user may use that information to correctly navigate within an area where jamming or spoofing may be occurring.
