卫星转发器使用寿命与卫星点波束覆盖的指向次数直接相关,每一次点波束指向的转变都要付出很高的成本。这里针对卫星点波束覆盖的问题,提出的卫星点波束中心选取算法,为卫星点波束提供了最佳的覆盖方式。通过卫星的波束中心点对卫星的覆盖范围进行了计算。使用STK建立了相应的场景,对卫星的最佳中心点选取进行了分析,得到了船只通过大西洋时点波束的最佳中心指向点、点波束覆盖范围,证明了所提出的算法是正确的。
The service life of the satellite transponder is directly related to the number of satellite beam coverage pointing times, and the cost per point of the beam pointing transition is high. Here for the problem of satellite spot beam coverage, the proposed satellite spot beam center selection algorithm for the satellite spot beam provides the best coverage. The coverage of the satellite is calculated from the satellite’s beam center. Using STK to establish the corresponding scene, the best center point selection of the satellite was analyzed, and the best center point point and spot beam coverage of the ship when passing the Atlantic time point beam were obtained, which proves that the proposed algorithm is correct.
