Abstract

Satellite constellation design plays an important role in satellite networks. Network constellation system design can affect the effectiveness of current improvements of the communications link and the management of the entire network. The power requirement of the mobile stations and ground stations is very high in a geostationary Earth orbit communication system, which means the terrestrial terminal is hard to be made handheld for fifth generation mobile communications. The emergence of nongeostationary orbit satellites such as low Earth orbit satellites greatly compensates for the disadvantage of geostationary Earth orbit satellites. Based on the classical constellation design method, the orthogonal circular orbit constellation is proposed. The design objectives considered here are the following: global Earth coverage by low Earth orbit satellites, the duration of continuously covering one mobile station by one satellite is more than 9.57 min, the access satellite link duration time of the mobile station is more than 4.79 min, and the number of satellites and orbits is to be minimum.

5G移动通信无线网络卫星星座设计
卫星星座设计在卫星网络中起着重要作用。网络星座系统的设计会影响当前通信链路改进的有效性和整个网络的管理。在地球静止轨道通信系统中,移动站和地面站的功率要求非常高,这意味着地面终端很难用于第五代移动通信。近地轨道卫星等非地球静止轨道卫星的出现极大地弥补了地球静止轨道的不足。在经典星座设计方法的基础上,提出了正交圆轨道星座。这里考虑的设计目标如下:近地轨道卫星覆盖全球地球,一颗卫星连续覆盖一个移动站的持续时间超过9.57 min,移动站接入卫星链路持续时间大于4.79 min,并且卫星和轨道的数量是最小的。
