Description
A prototype GPS spoofer detection and localization network will be designed and simulated. GPS spoofing will be detected with a multi-layered set of defenses using a network of receiver-detectors (RD). Each RD will include a tactical data link that includes a GPS-independent time synchronization and relative ranging function. Each RD will detect spoofing by monitoring the GPS signals, GNS-INS Kalman filter innovations, position, velocity, and time. The network of RDs will also compute a relative position estimate that will be used to protect against GPS spoofing. Once detected, spoofers will be localized on a per-channel basis to ensure localization of multiple spoofers in arbitrary configurations. The design will be documented and a fabrication plan prepared for construction during Phase II.
