  • System and method for detecting interference in global positioning satellite signals
    Patent number: 7512492
    Abstract: A system and method are provided for detecting local interference in GPS signals. A plurality of remotely located GPS receivers are capable of receiving GPS signals and producing GPS related data. A monitoring station is capable of storing at least one expected GPS parameter for each of the plurality of GPS receivers. A first processor at the monitoring station is programmed to determine, for each of the GPS receivers, whether said GPS related data deviates from any of the at least one GPS parameter by more than a predetermined range of error, and for issuing a warning in response thereto.
    Type: Grant

  • System and method for detecting interference in global positioning satellite signals
    Patent number: 7366611
    Abstract: A system and method are provided for detecting local interference in GPS signals. A GPS receiver is capable of determining its GPS coordinates. A memory is capable of storing an initial location of the GPS receiver and a user-defined range of error. A processor is programmed to determine whether GPS coordinates from the GPS receiver differ from the initial location by more than a range of error, and for issuing a warning in response thereto.
