摘要： A satellite transmission capturing method for the GPS receiver whereby PLL operation is stopped until the demodulation intensity of a demodulator reaches a predetermined level. The frequency of the reproduced carrier of the demodulator is consecutively changed in increments of a frequency range wider than the PLL capture range in search for satellite transmissions. This allows the demodulation intensity to reach the predetermined level in fewer frequency changing steps than ever before. Thus the time required to capture the desired satellite transmission is reduced. Where the integral time constant of a low pass filter in the demodulator is set to a value smaller than that in effect during PLL operation until the demodulation intensity of the demodulator reaches the predetermined level, a wide band demodulation intensity curve is used in search for satellite transmissions until that level is exceeded. This further widens the frequency range in which to search satellite transmissions, and the time required to capture the desired satellite transmission is further shortened accordingly.

摘要： A method for searching a carrier frequency and code phase of a signal received by a GPS receiver. The method includes steps of: quantizing the received signal; sampling the quantized signal at a first speed by a carrier frequency generated in the receiver; storing the samples in memory at a first speed; reading the samples from memory at a second speed; and determining the correlation between a code of the carrier frequency generated in the receiver and the received signal. The second speed is faster than the first speed.

摘要： 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.

摘要： 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.
