卫星运动特性对地面站天线系统的影响分析

Analysis of the Influence of Satellite Motion Characteristics on the Ground Station Antenna System

由于广播电视卫星的摄动和漂移现象，对地面站有效对准所上行的卫星造成干扰，针对此现象，通过研究卫星的运动特性，总结卫星运行的变化规律，根据其特性，结合上行站天线系统口径、频段和控制系统等因素，对天线系统进行周期性的校正和跟踪方法进行简要介绍，有效避免由于卫星8字漂移对传输发射造成的不利影响。

Due to the perturbation and drift phenomenon of the radio and television satellite,it causes intefference to the satellite in which the ground station is effectively aligned. By studying the motion characteristics of the satellite, the variation law of the satellite operation is summed up. According to the characteristics of the satellite, the antenna system is combined with the antenna system caliber ,frequency section and control system. The periodic cori＇ection and tracking methods are briefly introduced, which can effectively avoid the adverse effects of satellite 8 character drift on transmission and emission.
