Abstract
The performance of a Global Positioning System (GPS) receiver usually depends on the tracking loops, so they can be considered the heart of the GPS receivers. It has been proven that the carrier tracking loop is more sensitive to noise and interference than the code tracking loop. Therefore, the carrier tracking loop can be used as a means for investigating the GPS receiver performance in presence of interference. In this paper, closed form analytical expressions for the carrier tracking loop phase error are derived in presence of different types of interference signals such as continuous wave interference, narrowband interference, partial band interference, broadband interference, match spectrum interference, and pulse interference. Also the carrier-to-noise ratio threshold is analytically derived. The derived analytical expressions have been validated with the aid of simulation experiments.
