摘要
介绍了两种适合分布式防空C3I系统的坐标变换体系,一种为基于球极平面投影的坐标变换体系,另一种为基于地心直角坐标的坐标变换体系。前一种方法在一定地理范围内可以满足实际系统对精度的要求,变换公式相对简单;后一种方法可以在全球范围满足高精度的变换要求,变换公式略为复杂。最后,对这两种坐标变换体系进行了误差分析。
Two coordinate transformation systems for the distributed air-defense C3I are presented. The first is based on stereographic projection, its accuracy is satisfied the needs in practice within the given range and its formulas are relatively simple; the second is based on earth-centered earth-fixed coordinates (ECEF), it is exact on a global scale and its formulas are rather too complicated. Finally, error analysis are made for them.
