Abstract
The portable GPS-receiver for a system of personal safety having such attributes, as diminished power consumption, overall dimensions and weight, because the input unit contains the multichannel digital correlator with N=by 8 to 12 channels of parallel processing connected with the microprocessor equipped with permanent storage unit for storage of the programs of signal processing and operative storage for data storage by activity in a standard mode without interlock of GPS signals, thus the microprocessor of the output unit is connected by trunks of a data exchange to the former of clock signals and heterodyne frequencies of an input unit, with an input-output unit of the data, with the transceiver unit and in addition provided with the permanent storage unit for storage of the programs of signal processing and operative storage for data storage and samples of the multichannel digital correlator for operation in conditions of interlock of GPS signals, and each of N of channels of the multichannel digital correlator is equipped with K inphase and Ko quadrature correlators, where K=20 to 40, connected with the appropriate storage units ensuring a capability of a simultaneous correlation of GPS signals with K copies of C/A code, shifted on half of digit of C/A GPS code, and coherent accumulation of results of a correlation on an interval equal to duration of epoch of C/A code.
