Satellite comprehensive test uplink remote control modulation signal real-time monitoring system and method

Abstract

The invention discloses a system and method for real-time monitoring of uplink remote control modulation signals for satellite comprehensive testing. Conditioning equipment; used to demodulate and decode the remote control signal and send the frame-synchronized remote control command data and demodulation status information to the receiver of the real-time monitoring and comparison device; used to send the remote control command data to the receiver Stopwatch equipment for inversion, etc. The invention realizes the comparison of the correctness of the remote control command information and the real-time monitoring of the quality of the modulated signal for the uplink remote control modulation signal in the satellite comprehensive test process, and can quickly isolate or locate the fault of the ground test system when an abnormal response to the remote control command occurs during the satellite comprehensive test.

Description

technical field [0001] The invention relates to the technical field of satellite testing, in particular to a system and method for real-time monitoring of uplink remote control modulation signals for satellite comprehensive testing. Background technique [0002] With the continuous development of satellite overall technology, satellites have more and more radio frequency channels and higher frequency bands, and the electromagnetic environment in which satellites are located is becoming more and more complex, which is often encountered in satellite test sites, especially in wireless tests. The abnormal response of commands caused by some reasons, some of which come from the failure of the comprehensive test system, can generally be ruled out by searching for relevant records, but it is generally based on the ground communication protocol level, and once the radio frequency part is checked Or the modulated signal, it is usually impossible to rule out whether the uplink remote ...

[0002] With the continuous development of satellite overall technology, satellites have more and more radio frequency channels and higher frequency bands, and the electromagnetic environment in which satellites are located is becoming more and more complex, which is often encountered in satellite test sites, especially in wireless tests. The abnormal response of commands caused by some reasons, some of which come from the failure of the comprehensive test system, can generally be ruled out by searching for relevant records, but it is generally based on the ground communication protocol level, and once the radio frequency part is checked Or the modulated signal, it is usually impossible to rule out whether the uplink remote control modulation of the comprehensive test system is correctly modulated or whether the modulation content is correct, and it is even more impossible to determine whether the relevant stand-alone functions on the star are abnormal. It is beneficial to model development, so it is very necessary to compare the correctness of remote control command data and real-time monitoring of modulation signal quality for satellite uplink remote control modulation signals, which will be very conducive to rapid troubleshooting, analysis and positioning of faults. In the current domestic satellite field, Usually, the comprehensive test system directly modulates the uplink remote control signal and sends it to the satellite. It lacks the comparison of the correctness of the remote control command information and the real-time monitoring of the quality of the modulated signal. Positioning or satellite-related stand-alone functions are abnormal. The present invention is a real-time monitoring system and method for satellite comprehensive testing uplink remote control modulation signals to solve the above problems. At present, no description or report of similar related technologies has been found, and similar domestic and foreign similar technologies have not been collected yet. data of
