Abstract

The weak strength of GPS signal makes it very vulnerable to jamming. This calls for appropriate modeling and implementation of GPS signal source and jammers that are used to jam GPS signal. The present work describes a simple and efficient way to simulate GPS signal using MATLAB with focus on investigation of GPS signal jamming and devising an anti-jamming technique to counter different jamming scenarios besides Additive white Gaussian noise (AWGN). The jamming types influencing GPS Signal have been identified and suitable jamming scenarios have been modeled using MATLAB. The effect of each jamming signal type on GPS signal has been quantified by estimation of Bit error rate (BER) for different jamming to signal (J/S) ratio. A background study of different anti-jamming techniques for GPS signal has been carried out and Turbo coding has been implemented as a suitable measure to counter the effect of GPS signal jamming.
