编队微小卫星变码速率星间通信系统仿真研究

Research of Volatile Code Rate Inter-satellite Communication System for Micro-satellite Formation-flying Constellation

本文以3颗微小卫星在同一个轨道面内编队飞行并对地进行三维立体测绘为背景,根据编队飞行星间链路的特殊要求,推导了低轨道编队卫星星间链路的计算公式;提出了根据星间通信距离改变码速率的通信方案,并对编队飞行卫星变码速率通信系统进行了仿真研究。

This paper bases on three micro -satellites which formation fly on a same orbit and perform three dimension solid mapping for terra. The calculating formula of LEO formation - flying satellite inter - satellite links is guided according to the special require of formation - flying micro - satellite inter- satellite links. A new communication project which changes code rate according to the inter - satellite communication distance is brought forward to suit this situation. And the simulation of volatile code rate inter - satellite communication system for micro - satellite formation - flying constellation is performed.
