SIGNAL PROCESSING OF SATELLITE NAVIGATION SYSTEMS WITH QUADRATURE MULTIPLEXING AND FREQUENCY DIVISION
Annotation
New algorithms for processing of signals from global satellite navigation systems are proposed. The algorithms increase the system resolution, accuracy of the time delay estimation, and improve the signal-to-noise ratio in the problems of navigation, signal detection and recognition. An estimate is derived for accuracy of navigation problem solution with the use of differential measurements. Results of experimental processing of GLONASS signals with frequency division multiplexing are presented to demonstrate the increase in signal-to-noise ratio when the algorithm of joint processing of signal from two navigation spacecraft is applied.
