Jammer Design for GPS Signals

Beni Priel and Ben Zion Bobrovsky

Abstract:	Interference of GPS has recently attained much attention. The interference increases the signal jitter, and the GPS accuracy is distorted. In case the power of the interference is increased, loss of lock of GPS is attained. The mean time to lose lock - MTLL depends on loop parameters such as signal to noise ratio, interference bandwidth and also on velocity of receiver. The time to lose lock is the time of exit from a boundary (separatrix) which separates between the domain of locked state and the unlocked domain. The MTLL depends on exit point from the separatrix and is found explicitly. The MTLL is used as criterion for interference design It is found that a wideband interference is better than a singletone one, and the interference bandwidth which attains lowest values of MTLL s’hould be approximately the same as the bandwidth of the tracking loop.
