摘　　要：针对静止轨道遥感卫星的标称网格数据生成方法进行研究,介绍了标称网格的基本概念;然后,分别给出了NGP标称网格、NNGP标称网格以及画幅式成像标称网格3种标称网格的计算方法;最后,设计实验比较了3种标称网格数据生成方法的正反算结果,并分析了不同方法正反算结果在不同方向、不同区域之间的差异。对于静止轨道遥感卫星标称数据的发布、应用以及不同网格数据的转换等工作都具有十分重要的意义。Nominal grid data generation method of geostationary remote-sensing satellite was studied in this paper. Firstly, the basic concept of nominal grid was introduced; then, the computing method of NGP nominal grid, non-standard NGP nominal grid, and frame perspective imaging nominal grid were given; finally, the experiment was designed to compare the results of forward and inverse solution of the three kinds of nominal grid data generation method, and the differences of the forward and inverse solution of the methods among directions and regions were analyzed. This research had a very important value for the release, application and transformation of different nominal grid data of geostationary remote-sensing satellite.
