Abstract
A GPS receiver comprising a plurality of demodulators. A satellite transmission search range is divided into as many frequency ranges as the demodulators so that one demodulator is assigned to one divided frequency range. Each demodulator searches a target satellite transmission within the frequency range assigned thereto. The GPS receiver of this construction significantly reduces the time required initially to capture the desired satellite transmission.
