中文摘要: 根据对GMS-4地球静止卫星所发定位网格数据的分析,发现同一纬线上两定位格点间象素分辨率的变化率基本保持不变。可以利用等比级数的原理计算象素分辨率,从而确定象素的地理位置。据此设计的非线性插值方法明显优于线性插值法。

Abstract:Based on the analysis of grid data for navigation from GMS-4,it is discovered that the vari bility of pixel resolution between two grid points at the same latitude may be used as a constant. The resolution of each pixel can be computed according to the principle of geometrical progression. The geographical position of the pixel, in turn, can be determined. A method of nonlinear interpolation designed from this result has more advantage than the linear interpolation.
