针对现有中继卫星系统主要为特定用户服务、难以满足蓬勃发展的航天事业带来的海量天基测控需求难题,研究了利用现有地球同步通信卫星系统和近地轨道通信卫星星座对近地卫星测控的可行性和实用性,分析了它们的优缺点,并给出了中继测控应用实例。理论分析、实际用例和完成的仿真计算表明,上述3种类型的卫星系统设计都可以为近地卫星提供中继测控服务,但由于各系统设计的初衷和服务对象不同,在具体的应用效果上各有优缺点,这些优缺点为不同需求的卫星中继测控服务提供了多样性选择,用户可以据此根据其卫星平台测控管理要求、有效载荷的应用需求和性价比等因素,选择最佳的天基中继测控方式,实现高覆盖和低成本。
Abstract：With the boom of commercial aerospace industry,it is difficult to meet the all demand on massive space-based TT&C service for the existing tracking and data relay satellite system is mainly designed for special users.This paper probes the feasibility and practicability of space-based TT&C service for LEO satellites by using existing geosynchronous communication satellites and LEO satellite constellations.Our theoretical analysis,given actual use cases and our simulation calculations show that these three types of satellite system can provide TT&C service for LEO satellites.However,due to the difference of original intention and service objects,each system has its own advantages and disadvantages,which provide a variety of choices for LEO satellite users.Then the users can choose the best space-based TT&C service to achieve high coverage and low cost.
