摘要
在GPS导航应用中,经常涉及到WGS84坐标系、导航坐标系以及载体坐标等的相互转换。从欧拉角的旋转公式推导出发,详细研究了这几种坐标系的转换关系,推导出其在工程应用中的转换公式,并对其在姿态求解中的应用进行了论述。该公式已通过Vc6程序实现,并通过了工程实践数据的验证。该公式计算简单,便于实现,有较好的应用价值。
WGS84, topocentric coordinate system and carrier cgordinate system are widely used in GPS navigation and positioning. This paper deduces the transformation relations of these three coordinate systems in detail and gets the transformation formulars based on the deduction of Eulerian angles rotation formulas, then it discusses the attitude determination using coordinate transformation,The formulas which have been programmed using Vc 6 and validated by project data, can be easily calculated and practiced with high application value.
