Abstract
The jammer response circuitry of the present invention operates to control correlation circuitry in a GPS receiver based on an occurrence of a transmission from a wireless transmitter, thereby avoiding performance degradation in th GPS receiver due to interference caused by the transmission. In general, the jammer response circuitry activates a control signal during the transmission, thereby temporarily stopping the operation of the correlation circuitry. More particularly, the accumulation of results of a correlation of a received signal with a generated frequency and a generated code having numerous time offsets is temporarily stopped when the control signal is activated and resumes operation when the control signal is deactivated.
