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.
