Abstract
Description
Technical Field
[0001] The present invention relates to the field of aerospace measurement and control technology, and in particular to a satellite-ground random relay integrated measurement and control system. Background Art
[0002] During the satellite's in-orbit operation, the ground needs to conduct regular remote control and telemetry of the satellite. At present, the ground usually adopts four methods to measure and control satellites: 1) conventional measurement and control through ground measurement and control stations; 2) continuous measurement and control through relay satellites; 3) S-band multiple access (SMA) short message measurement and control through relay satellites; 4) random access measurement and control through ground random measurement and control stations.
[0003] In order to meet the measurement and control requirements of measurement and control, random, relay continuous and relay short messages at the same time, the design of the measurement and control scheme needs to include four modes: ground measurement and control, ground random, relay continuous measurement and control and relay short message measurement and control. The existing measurement and control system usually includes measurement and control transponders, microwave networks, relay terminals, relay measurement and control fixed-type, measurement and control transceiver antennas, relay transceiver antennas, random terminals, random transceiver antennas, etc. Among them, the measurement and control transponder consists of a spread spectrum baseband processing unit, a transmitting channel and a receiving channel, and is mainly responsible for modulating and forwarding the downlink telemetry data from the satellite computer and demodulating the uplink remote control data from the ground station. The relay terminal consists of a relay baseband processing unit, a transmitting channel and a receiving channel. Its function is to modulate and forward the return telemetry data and return short message data from the satellite computer and demodulate the forward remote control data and forward relay SMA short message data from the relay satellite. The Suiyu terminal consists of four parts: the Suiyu baseband processing unit, the transmitting channel, the receiving channel 1 and the receiving channel 2. It is mainly responsible for modulating and forwarding the return message data from the satellite computer and demodulating the uplink Suiyu access data and uplink Suiyu short message data from the ground station. Since the measurement and control frequencies and measurement and control systems of ground measurement and control, relay measurement and control and Suiyu measurement and control are independent of each other, different frequencies and different systems can be selected. Therefore, the measurement and control transponder, relay terminal and Suiyu terminal are designed as three different single machines.
[0004] However, due to the different frequencies and codes of satellite-to-ground TT&C, relay TT&C and random TT&C, satellite-to-ground TT&C, relay TT&C and random TT&C are independent of each other. The ground baseband processing module and the transceiver channel are designed in the TT&C transponder. The relay baseband processing module and the transceiver channel are designed in the relay terminal. The random baseband processing module and the transceiver channel are designed in the random terminal. This makes the system heavy and costly, which makes it difficult to meet the requirements of small satellites for lightweight and low cost. Summary of the invention
