Abstract
A signal processing circuit for a GPS receiver wherein the search time for a code phase is decreased to decrease the time required for catching of radio waves of an artificial satellite without increasing the circuit scale very much. The signal processing circuit comprises, in addition to a carrier correlator and a code correlator, a change-over circuit for changing over the connection to the code correlator so that the code correlator operates as a carrier correlator before wave forms of an object artificial satellite are caught but operates as a code correlator after waveforms of the object artificial satellite are caught.
