| 摘 要： | 为了提升卫星导航信号处理软件RTKLIB的直角坐标转换至大地坐标算法的性能,本文基于牛顿迭代算法的思路,在Bowring直接解法基础上提出一种引申迭代算法。经过理论分析和测试实验数据对比,本文证实了引申迭代坐标转换算法相对于RTILIB现有的一般迭代坐标转换算法,具有迭代次数更少、精度更高的特点,更适用于高度坐标h取值较大的情形。

| Abstract: | To promote the performance of RTKLIB software in processing the transformation from the Cartesian coordinates to geodetic coordinate, this paper proposed an algorithm based on the Newton iterative algorithm extended out from the Bowring''s method. By theoretical analysis and experimental test data contrast, it has been demonstrated that comparing with the general iterative coordinate transformation algorithm existing in RTKLIB, the proposed extended iterative coordinate transformation algorithm has the characteristics of less iteration times and higher accuracy and is more suitable for the situation when the value of height coordinates (h) is large. |
