多用户多任务的中继卫星捕获跟踪技术研究

Research on Acquisition and Tracking of Data Relay Satellite Based on Multi-user & Multi-mission

针对中继卫星用户数量及跟踪任务不断增多,跟踪模式复杂,任务响应速度要求快的特点,文章给出了对单个用户星捕获跟踪的典型过程,进而提出多用户多任务捕获跟踪策略,其可根据用户星类型、用户星优先级、任务中继服务时刻、可服务时间窗口等条件,经过合理的任务规划,可以同时实现为多个用户服务、优化星地资源配置、简化操控技术。文中应用两副天线跟踪6个目标,验证了中继卫星完成多用户多任务捕获跟踪任务的可行性。

A typical acquisition and tracking process for a single user satellite is given. Basedon it, acquisition and tracking strategy for multi-user and multi-mission is presented in order to fulfill the requirement of increased users and missions, to be adapted for complicated tracking modes and fast response speed. This strategy can be applied to serve multiple users, to optimizeresources and to simplify operation technique according to user type, user priority, missiontime and duration and so on by reasonable mission planning. An example mission of two antennaes tracking six users applying above strategy is given to validate the feasibility of multi-user and multi-mission capability of data relay satellite.
