THE INFLUENCE OF CONDITIONS FOR PASSING GLONASS AND GPS SATELLITE RADIO NAVIGATION SIGNALS ON THE ERRORS OF DEFINING RELATIVE COORDINATES

Аннотация

The influence of the conditions for passing GLONASS and GPS satellite radio navigation signals on the errors of defining relative coordinates is studied.

The retransmission of navigation spacecraft signals of the GLONASS and GPS systems is known as repeated radiation after reception and processing in relaying equipment (further a repeater). Signal processing in a repeater can include intensification, frequency conversion, filtration and additional coding of a navigation spacecraft signal. The relayed signal passes the radio channel and goes on to the retransmitted signal receipt and processing equipment (RSRPE). The RSRPE processes signals. The signals are transferred by a repeater according to the algorithm provided for the task. It is here that the measurement of radio navigation parameters (parameters of delay, Doppler frequency shift etc.) of navigation spacecraft signals are received by the object and the completion of navigation time task for the object is finished. The repetition of navigation spacecraft signals from a board of an object can be used for different purposes.
