Abstract
According to one general aspect, an apparatus may include a receiver, a processor, and a correlator circuit. The receiver may be configured to receive a satellite navigational system signal. The processor may configured to, if an interference signal is detected: receive an indication of a detected interference signal, and generate a modified coarse/acquisition (C/A) code, wherein the modified coarse/acquisition (C/A) code includes a null value for at least one frequency portion associated with the interference signal. The correlator circuit may be configured to, if an interference signal is detected, generate a correlated signal in which the interference signal has been at least partially removed by combining the modified C/A code and the satellite navigational system signal.
