卫星备份星漂星控制策略研究

Research on Control Strategy of Satellite Backup Star Drift

在星座备份策略研究中,替换策略的优化至关重要,从而形成一对卫星协同工作,一旦工作卫星出现故障,备份卫星可以经过轨道机动完成对故障卫星的快速更换。为有效应对卫星出现故障等紧急情况,保障广播电视安全播出和通信业务安全畅通,将东四平台卫星B作为东四平台卫星A的应急备份,在接到漂星任务后,要求备份星5天内漂至目标轨位。对卫星漂星前准备、漂星控制过程和漂星期间机动方案设计制定了相关策略。

In the study of constellation backupstrategies,the optimization of replacement strategies is crucial to form,a pair of satellites working together.Once the working satellite fails,the backup satellite can quickly replace the failed satellite through orbital maneuvering.In order to effectively respond to emergency situations such as satellite failures,and to ensure the safe and smooth broadcasting of radio and television and communication services,Dongsi Platform Satellite B is used as an emergency backup for Dongsi Platform Satellite A.After receiving the task of drifting the star,the backup star is required to drift to the target orbit within 5 days.This article has formulated relevant strategies for the preparation of the satellite,the control process of the drifting star,and the design of the maneuvering plan during the drifting star.
