Phased multi-rate self-adaptive measurement and control system of mars exploration deep space spacecraft

Abstract

The invention provides a phased multi-rate self-adaptive measurement and control system of a mars exploration deep space spacecraft, which is characterized by comprising an X-frequency range deep space responder, a high stable frequency source, an X-frequency range solid state power amplifier, an X-frequency range high-power traveling wave tube, an output multiplexer, an input low noise amplification receiving unit, a wide-beam low-gain receiving antenna, a wide-beam low-gain transmitting antenna, an intermediate-gain transmitting antenna, a two-dimensional driven high-gain measurement and control antenna and a waveguide switch. According to the invention, the problems of communication with the ground and measurement and control of the deep space explosion spacecraft are solved in the whole process that the deep space explosion spacecraft is launched from the earth, flies from the earth to the mars cruising segment and flies around the mars. The phased multi-rate self-adaptive measurement and control system has an excellent effect for the mars exploration deep space spacecraft to complete the measurement communication control from the earth orbit flight to the mars orbit flight. The phased multi-rate self-adaptive measurement and control system can solve the key difficult points of measurement and control of the mars deep space spacecraft and has a certain effect on the aspect of improving the reliability of the deep space spacecraft.

Description

technical field [0001] The present invention relates to the ground-to-ground communication technology of Mars exploration deep-space spacecraft, especially a kind of ground-to-ground communication technology that can be used for the whole process of deep-space spacecraft, uninterrupted ground remote control, remote control, and distance measurement within the distance from the launch of the earth to the orbit around Mars. The system of electronic equipment, specifically related to the staged multi-bit rate adaptive measurement and control system of the Mars exploration deep space spacecraft. Background technique [0002] When a spacecraft works in space, it needs the ground to perform remote control, telemetry, and ranging. To accomplish the above work, the spacecraft should be equipped with corresponding systems. In the existing earth satellite measurement and control technology, the measurement and control of the spacecraft adopts a fixed code rate remote control, and the...
