  • Methods and apparatus for detecting spoofing of global navigation satellite system signals using carrier phase measurements and known antenna motions
    Patent number: 9958549
    Abstract: Methods and systems that can detect GNSS spoofing attacks and that do not require explicit or implicit knowledge of exact position or attitude and that provide hypothesis test statistics, threshold values, and probabilities of false alarm and missed detection.
    Type: Grant
    Filed: September 20, 2013
    Date of Patent: May 1, 2018
    Assignee: Cornell University
    Inventors: Mark L. Psiaki, Steven P. Powell, Brady W. O'Hanlon

  • Real-time software receiver
    Patent number: 7305021
    Abstract: A real-time software receiver that executes on a general purpose processor. The software receiver includes data acquisition and correlator modules that perform, in place of hardware correlation, baseband mixing and PRN code correlation using bit-wise parallelism.
    Type: Grant
    Filed: December 22, 2005
    Date of Patent: December 4, 2007
    Assignee: Cornell Research Foundation, Inc.
