Because the satellite communication system is an open system, the satellite’s frequency resources and transponder power are limited. Although there are international organizations and satellite companies in various countries for orbit, frequency, and power allocation and coordination, satellite communications cannot be completely prevented from being interfered. The well-known Falun Gong interference with Xinnuo satellite is an obvious example. Articles on satellite communication interference are scattered in various professional newspapers. This article will discuss the causes, judgment methods and solutions of common interference in satellite communication, focusing on the practical methods of solving interference.
