Characterization of Receiver Response to Spoofing Attacks
(The Institute of Navigation, 2011-10)
Test procedures are developed for characterizing the response of civil GPS receivers to spoofing attacks. Two response characteristics are analyzed in detail for four representative GPS receivers: (1) the spoofer power ...

Test procedures are developed for characterizing the response of civil GPS receivers to spoofing attacks. Two response characteristics are analyzed in detail for four representative GPS receivers: (1) the aggressiveness ...
Opportunistic Frequency Stability Transfer for Extending the Coherence Time of GNSS Receiver Clocks
(Institute of Navigation, 2010-09)
A framework is presented for exploiting the frequency stability
of non-GNSS signals to extend the coherence time
of inexpensive GNSS receiver clocks. This is accomplished
by leveraging stable ambient radio frequency ...
The GPS Assimilator: a Method for Upgrading Existing GPS User Equipment to Improve Accuracy, Robustness, and Resistance to Spoofing
(2010-09)
A conceptual method is presented for upgrading existing GPS user equipment, without requiring hardware or software modifications to the equipment, to improve the equipment’s position, velocity, and time (PVT) accuracy, to ...
