Study on countermeasures against electromagnetic interference around large deep space station

Deep space TT&C(tracking,telemetry and command) activities are characterized by large signal space attenuation,prolonged transmission time and complex propagation environment,and electromagnetic interference has a great influence on the activities.This paper analyzes the electromagnetic interference status of a deep space station,distinguishes various interference sources,and studies the commonly used countermeasures against electromagnetic interference.Based on the electromagnetic environment monitoring and management information system,the realization of real-time electromagnetic environment monitoring in deep space station is studied,and the electromagnetic interference monitoring methods and countermeasures suitable for deep space station are explored,so as to effectively protect the deep space station from the physical mechanism.
