LEO卫星接入TDRSS的可行性分析与仿真

Feasibility Analysis and Simulation of LEO Satellite Accessing to the Tracking And Data Relay Satellites System

该文讨论了使用固定天线和中低发射功率的LEO卫星接入到跟踪与数据中继卫星系统(TDRSS),并通过跟踪与数据中继卫星(TDRS)来实现空-地数据传输的可行性。文中给出了LEO卫星与TDRS进行通信需满足的前提条件,提出了通过计算机仿真来计算LEO卫星与TDRS全天通信时间和通信业务量的一般思路和具体实现方法,为论证具有固定天线的LEO卫星接入TDRSS的可行性提供了依据。

This paper discusses the feasibility of LEO satellite of fixation antenna and low or middle power accessing to the TDRSS and realizing space-ground data transmission through TDRS. The precondition of communication between LEO satellite and TDRS are given, then the general idea and method of computing the data throughout in bits and on day are provided by computer simulation, this method provides bases to test the feasibility of LEO satellites of fixation antenna accessing to the TDRSS.
