INTEGRATED RECEIVER OF SIGNALS OF SATELLITE RADIO NAVIGATION SYSTEMS

摘要

FIELD: radio navigation. SUBSTANCE: invention refers to receivers of signals of satellite radio navigation systems GPS and GLONASS of frequency range L1. Receiver incorporates intercoupled radio frequency converter, N-channel digital correlator. computer as well as former of signals of time marks. This former includes counter which first input is clock signal input and which output is signal output of own time marks of receiver. Former of load period signal whose second input and output are coupled to output and second input of counter as well as first and second synchronization units whose signal inputs are inputs of signals of first and second outside time marks of receiver are linked to first input of counter. Period register whose input is connected with the aid of data exchange bus to computer is linked to third input of counter. Switch whose signal input is coupled to output of first synchronization unit is also linked to output of counter. In this case controlling input of switch is connected to output of register that controls switch whose input is linked by means of data exchange bus to computer. Switch is linked with output which is output of measurement gates of former of signals of time marks to proper inputs with the use of one channel of N-channel digital correlator. Register of time position of second outside time mark whose output is additional output of former of signals of time marks is linked to digit outputs of counter and output of second synchronization unit. EFFECT: capability to synchronize processes of correlation processing and solving of navigational problem with reference to outside time signals. 1 cl, 5 dwg
