Daniel Shepard. Honors Thesis Symposium. 4/21/2011. What is Civil GPS Spoofing?. The structure of the civil GPS signal is well known, and the signal can be readily reproduced. A spoofer seeks to alter a target receiver’s Position-Velocity-Time (PVT) solution by transmitting fictitious GPS signals. . and. Tropical . Climate. Variability. . Peter . Brandt.
