Abstract

The invention relates to a full-coverage multi-channel multi-frequency band measuring and control system of a deep space electric propulsion asteroid spacecraft, comprising a star service computer and a plurality of deep space responders and an ultra high frequency (UHF) relay transceiver which are connected with the star service computer; the deep space responders are further connected with multiplexers and high-stability crystal oscillators, and the multiplexers are connected with all-directional receiving antennas and large-diameter directional antennas; the deep space responders are also connected to the input ends of low-power solid-state amplifiers and high-power traveling wave tube amplifiers through switch arrays, and the output ends of the low-power solid-state amplifiers and the high-power traveling wave tube amplifiers are connected to all-directional transmitting antennas and low-gain transmitting antennas through the switch arrays; and the UHF relay transceiver is connected with a relay transceiving antenna. According to the invention, the full-coverage multi-channel multi-frequency band measuring and control system of the deep space electric propulsion asteroid spacecraft can meet all-process star-earth remote control, remote detection, range finding and other requirements of the deep space asteroid spacecraft as well as the relay communication requirements of the asteroid spacecraft simultaneously, and has the advantages of high reliability, resource saving and low cost.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a full-coverage, multi-channel and multi-frequency band measurement and control system for a deep-space electric propulsion asteroid spacecraft. Background technique [0002] When deep-space spacecraft work in space, they need the ground to perform remote control, telemetry, and ranging. To complete the above work, the spacecraft should be equipped with a corresponding communication system. Existing deep-space spacecraft adopt chemical thrust technology, which can maintain a directional attitude toward the sun for a long time during the flight process. The spacecraft measurement and control antenna adopts a limited beam design to meet the communication requirements of the spacecraft and ground, and only includes the communication frequency of the spacecraft and the ground. [0003] With the development of my country's aerospace technology, it is necessary to carry out the development of as...
