  • Systems and methods for mobile terminal location verification
    Patent number: 8599068
    Abstract: Methods and systems for using W-code to extend anti-spoof capability to civilian GPS receivers for verifying locations of mobile terminals are disclosed. A system for verifying a reported location of a mobile terminal includes a receiver of the mobile terminal and a verification processor. The receiver processes the radio ranging signals to generate measured quantities related to the W-code to the verification processor. The receiver also provides the reported location of the mobile terminal to the verification processor. The verification processor generates expected quantities related to the W-code based on the reported location of the mobile terminal. The verification processor further compares the measured quantities related to the W-code to the expected quantities related to the W-code to verify the reported location of the mobile terminal.
