Abstract

This paper considers the problem of interference suppression in GPS coarse/acquisition (C/A) signals. Particularly, an anti-jam receiver is developed, utilizing the unique repetitive feature of the GPS C/A-signal. The proposed receiver does not require the knowledge of the transmitted GPS symbols or the satellite positions. It utilizes the repetition of the Gold code within each navigation symbol to simultaneously suppress the interference of all satellites.
