Problems solved by technology

In the prior art solutions, the shielding of weak signals is usually only shielded from the transmission cable, such as using twisted pair or shielded cables to transmit weak signals, but the shielding effect of this measure on the signal is not ideal, and it cannot completely solve the problem of detectors. The problem of interference, when there is a single machine on the star that generates large electromagnetic interference, it will still have a large interference to the detector

Abstract

The invention relates to a grounding device for a satellite detector, which has: a plurality of grounding wires, which are used to connect with multiple signal loops of the satellite detector, wherein the lengths of the grounding wires are the same; and a grounding structure, It is used to ground all ground wires. Furthermore, the invention relates to a method for grounding a satellite probe. The invention can greatly reduce the electromagnetic interference to satellite detectors caused by a stand-alone machine on the star, and prevent the satellite detectors from interfering with other devices at the same time.

Description

technical field The invention relates to the fields of satellite signal transmission and electromagnetic shielding, in particular to a grounding device for a satellite detector. Furthermore, the invention relates to a method for grounding a satellite probe. Background technique Electromagnetic compatibility design of spacecraft occupies a very important position in model development. On the one hand, it is because electronic equipment on board, especially high-power radiation signal sources, will generate more or less electromagnetic interference energy. On the other hand, satellites in orbit When running, it will inevitably be affected by the sun's ultraviolet rays and external charged particles. A good electromagnetic compatibility design can reduce or even basically avoid the adverse effects of electromagnetic interference on satellites. The electromagnetic compatibility design of spacecraft mainly includes grounding design and lap design. Good grounding can suppress ...
