摘要
针对于卫星物联网的应用,采用6个低轨近极圆轨道面,太阳同步轨道,设计卫星星座。基于STK仿真,分析在采用少量卫星数的部署前期,不同卫星总数和不同相位角的星座对中国区域的覆盖情况(后期补星可实现全球全时段通信),并提出一种间隔轨道对称分布的卫星编队方法,以实现相同的卫星数对中国地区最大的完全覆盖率。
For the application of the Internet of Things(IoT),a satellite constellation is designed with six low-orbit near-polar circular orbits and sun-synchronous orbits.Based on STK simulation,the coverage of the constellation with different total number of satellites and different phase angles to China region in the early deployment period is analyzed(the global full-time communication can be realized by the satellite complement in the later period).In order to achieve the maximum complete coverage of the same number of satellites in China,a method of satellite formation with symmetrical distribution of interval orbits is proposed.
