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.

Center selection algorithm of satellite spot beam is proposed, thus to provide an optimal coverage for the satellite spot beam. Through the center of the satellite beam, the satellite coverage is calculated. With STK, the corresponding scene is established, and the selection of optimal satellite center point analyzed, and thus the optimal center directional point and spot beam coverage could be obtained at the time of the vessel’s passing the Atlantic. Experiment indicates that the proposed algorithm is feasible and correct.
