Visualization of TDRSS task operation based on STK

摘要:

跟踪与数据中继卫星系统搭建了中低轨航天器及其地面站通信的桥梁，实现了信息的实时传输，并提高了突发事件的应对能力。为对跟踪与数据中继卫星系统(TDRSS)调度业务的质量以及效率进行有效评估，在STK功能和接口的基础上，提出了基于STK通信组件(STKX)的跟踪与中继卫星实时场景仿真及其原型系统实现的技术方法，设计并实现了中继卫星针对中继业务的运行可视化系统。仿真结果表明，基于STKX的仿真平台能够满足中继卫星地面终端对中继任务的实时任务监控以及业务调度评估需求。

Abstract:

Tracking and Data Relay Satellite System(TDRSS) plays the role of communication bridge between medium or low orbit spacecraft and its ground station. It transmits real-time information and improves the response ability in emergency. In order to evaluate the quality and efficiency of TDRSS scheduling service, a method of TDRSS real-time visualization simulation and its system realization based on Satellite Tool Kit(STK) communication component(STKX) are presented. Simulation results show that the STK-based system satisfies the requirements of TDRSS real-time task monitoring and the evaluation of mission scheduling on ground terminal.
