Signal quality monitoring at controlling-correcting stations providing the differential operation mode of satellite navigation system customers

Using the methods of the Markov theory of random processes estimation, the algorithms are synthesized for signal and radio channels quality monitoring of the global satellite radio navigation systems at the controlling-correcting stations providing customers operation in the differential mode. The synthesized algorithms are based on analysis of signal characteristics in standard operation conditions. The algorithms do not require a special development of the models of possible signal disturbances and interference.
