Analysis of Effect of Electromagnetic Interference on Detection Data from the Data Transmitting System of the Electromagnetic Satellite

摘要

For magnetic detection satellite, it is hard to avoid electromagnetism interference on detection data. Whether Data transmitting system (DTS) could produce electromagnetism interference on detection data is uncertain. So we widely discussed and studied this problem. Firstly, in order to look for interference signal caused by DTS in routine data, the paper processed and analyzed the routine detection data from "Demeter" satellite and "Double Star" satellite, combining with some auxiliary data. And no abnormal signal caused by DTS has been observed. Secondly, for identifying unknown interference using the interference characteristics we have known, this paper summarized and analyzed the characteristics of the known interferences on detection data. The research achieved the conclusion that detection data didn't be affected by electromagnetism signal of DTS. Moreover, based on working principle of DTS, interference mechanism caused by DTS was simply analyzed, and some advices for avoiding interference were provided aiming at some potential problems. The analyzing process and research conclusions will offer an important reference for designing of preparing China Seismic Electromagnetic Satellite.
