摘要： In a signal processing apparatus a synchronizer acquires synchronization with the spreading code of an intermediate frequency signal converted from a signal received from a satellite in a global positioning system. A demodulator then demodulates a message contained in the intermediate frequency signal. A measuring unit outputs a primary signal to a predetermined signal line, the primary signal expressing positioning results for the apparatus as measured on the basis of the demodulated message. A secondary signal output unit attaches a predetermined header to a secondary signal and outputs the result to the predetermined signal line, the secondary signal containing at least the intermediate frequency signal, or a signal generated from the intermediate frequency signal.

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.

The synchronous acquisition unit detects a correlation between a spread code of a received signal from a GPS satellite and a spread code provided by the apparatus in order to detect a phase of the spread code of the received signal and a carrier frequency of the received signal. The synchronous hold unit has a plurality of channels and allocates one of the channels to one of a plurality of GPS satellites. The synchronous hold unit also establishes initial values based on the spread code phase of the received signal following detection by the synchronous acquisition unit as well as on the likewise-detected carrier frequency of the received signal, before starting synchronous hold of the spread code and the carrier frequency regarding the signal from the GPS satellite in question while decoding the signal from the GPS satellite.

Provided is a receiving device including a receiving unit for receiving a signal from a satellite, a frequency conversion unit for converting a frequency of the received signal into a predetermined intermediate frequency, a synchronization acquisition unit for carrying out synchronization acquisition and for detecting a carrier frequency, and a synchronization holding unit for assigning and setting, per satellite, a phase of the spread code and the carrier frequency to each of a plurality of channels independently provided in a corresponding manner to a plurality of the satellites to synchronously hold the spread code and a carrier and also for demodulating a message included in the intermediate frequency. The synchronization holding unit includes a spreading code generation unit for generating a spreading code synchronized with the spread code, and in a sleep period in which a positioning operation is not carried out, the synchronization holding unit causes only the spreading code generation unit to operate and a counter that the synchronization holding unit refers to also operates.
