Abstract

The invention provides a multi-band multi-channel combined deep-space relay system for a surround device, which is characterized in that a UHF relay communication machine is connected with a UHF microwave network, and a UHF receiving antenna and a UHF transmitting antenna are connected with the UHF microwave network; the UHF receiving antenna and the UHF transmitting antenna are used for connecting a lander / satellite vehicle UHF transceiver; the X relay communication machine is connected with the X relay receiving microwave switch, the X relay receiving microwave switch is connected with the X relay two-dimensional driving mechanism, and the X relay two-dimensional driving mechanism is connected with the X relay receiving antenna; and the X relay receiving antenna is used for connecting an X-band deep space responder of the Mars rover. High-speed interaction between lander front return data and the earth is achieved through the relay forwarding system, the defect that the lander is poor in direct ground measurement and control data transmission link capacity is overcome, and the method is not only suitable for Mars exploration tasks, but also can be used as reference for subsequent deep space and remote exploration tasks.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an orbiter multi-band multi-channel combined deep-space relay and forwarding system. Background technique [0002] Limited by the size of the detector, the lander of deep space exploration has weak direct ground measurement and control data transmission link capability. A small-scale, two-way, multi-mode relay communication link is built between the orbiters to achieve highly reliable interaction with the earth's forward and backward data throughout the entire stage. [0003] Foreign deep space probes and landers only use one mode of relay communication system. For example, the Mars probes of NASA and ESA of the European Union have only one UHF relay channel between the lander and the orbiter. In the near-fire stage, higher bit rate communication can be achieved. When in the far-fire or scientific exploration orbit, it is impossible to transmit the data of the Mars rover to t...
