摘要： The receiver includes: a correlation stage (7) formed of several correlation channels (7′) for receiving intermediate signals (IF) in order to correlate them, in operating channel control loops, with the carrier frequency and specific code replicas of visible emitting satellites to be searched and tracked, each channel having a correlator (8) in which at least one integrator counter (28, 29, 30, 31) provides, at the end of each determined integration period of the correlated signals, a binary output word whose value allows detection of the presence or absence of the visible satellite to be searched and tracked; and a microprocessor for processing the data drawn, after correlation, from the radio-frequency signals. The microprocessor configures at least one unused channel placed in parallel with one of the operating channels for searching and/or tracking the same visible satellite, the unused channel being configured so that the integration period of its integrator counter is different from that of the integrator counter of the operating channel.

摘要： The receiver (1) for radio-frequency signals (SV1, SV2, SV3, SV4), modulated by specific codes of transmitting sources, such as satellites (S1, S2, S3, 54), includes receiving and shaping means with frequency conversion for the radio-frequency signals for generating intermediate signals, a correlation stage formed of several correlation channels for receiving the intermediate signals and microprocessor means connected to the correlation stage in order to process the extracted data after correlation. Each channel includes a correlator in which the intermediate signals are correlated with at least two early and late replicas of the specific code of a visible transmitting source to be searched and tracked. The correlator further includes integrator counters for the correlated signals to provide a first amplitude value of the auto-correlation function of the early signals and a second amplitude value for the late signals. When multipath signals (SV1′, SV3′) are detected in the first operating channel, at least a second unused channel is configured, via the microprocessor means, and connected in parallel to the first channel. The second channel has the task of searching the maximum amplitude value between the two amplitude values of the first operating channel. The receiver, in particular of the GPS type, can be mounted in the case of a watch and powered by the energy accumulator or battery of the watch.

摘要： The method of determining the position of a radio-frequency signal receiver consists first of all in dividing the Earth's surface into N geographical regions as a function of the N channels available in the correlation stage of the receiver. At least one satellite in projection onto the Earth's surface has to be located in each of the N defined regions. The N channels of the correlation stage are each configured and switched on to search for a visible satellite in one of the N respective regions. Radio-frequency signal reception and shaping means pick up said radio-frequency signals and frequency convert them to provide intermediate signals to the correlation stage. Once one of the channels has detected a visible satellite in one of the N regions, the operation of all the other channels is interrupted by a stop block located in each of the other channels. Subsequently, certain other channels are configured and switched on for searching and tracking visible satellites in proximity to the first detected visible satellite. This allows precise position and time calculations to be made in the microprocessor means of the receiver. An approximate position is calculated as soon as at least four satellites are tracked by a direct method, before calculating the precise position of the receiver by a conventional iterative method.
