摘要： A GPS receiver that is capable of acquiring a GPS signal from a plurality of GPS satellites efficiently and at a high speed, and that is capable of performing a positioning calculation with a high degree of accuracy. The FFT processing result of the addition result from the PN code, stored in the memory, is multiplied by the FFT processing result of the IF data (the received data), stored in the memory, and by inverse-diffusing this result, a correlative value is obtained. By repeating this process while changing the combination of the PN codes to be added, and the synchronization acquisition processing, by a plurality of PN codes, is performed quickly with only a small amount of processing based on these results.

摘要： A satellite signal receiver apparatus by which the hardware scale can be suppressed while high speed synchronization is assured. A carrier frequency component is removed from a satellite signal. Then, adding those of signals obtained after every period interval of spread spectrum codes and signals stored in a memory which have a same phase at the period intervals and writing an addition result back into the memory are repeated by a number of times corresponding to plural periods thereby to accumulate signals corresponding to sums of the signals added over the plural periods at the period intervals into the memory. Then, correlation calculation is performed between the signals for the one period of the spread spectrum codes corresponding to the plural periods and a spread spectrum code of the receiver side to detect a correlation point between the satellite signal and the receiver side spread spectrum code.

摘要： The present invention is intended to provide the synchronization acquisition of signals received from four GPS satellites in a short time and with stability by the time in which an intermediate frequency carrier error of good accuracy can be obtained at the time of power-on sequence, for example. Prerequisites are that at least one GPS satellite signal be in the synchronization hold state, its intermediate frequency carrier frequency be known, the orbit information about that GPS satellite be stored in a storage section, and the position and current time of the GPS receiver be known. Under these prerequisites, an intermediate frequency carrier error is computed from the intermediate frequency carrier frequency, the position and velocity of the GPS satellite obtained from the orbit information and the current time, and the position of the GPS receiver. The intermediate frequency carrier frequency is corrected by the computed intermediate frequency carrier error. The signals received from other GPS satellites are acquired by use of the corrected intermediate frequency carrier frequency.

摘要： A satellite-signal reception-processing apparatus for receiving signals, which each have completed a spectrum-spreading process using a spreading code, from a plurality of artificial satellites. Then, on the basis of the received signals, the apparatus computes its own position and velocity. The apparatus includes a position-computation satellite determination section for searching for a set of specific artificial satellites each having its locus known and the time of transmission of its spreading code also known, using this set to compute the position of the apparatus. The apparatus also includes a velocity-computation satellite determination section for searching for a set of particular artificial satellites each having its locus known and the frequency of its carrier determined to be a stable frequency, and using this set to compute the velocity of the apparatus.
