摘要
Bowring直接解法由于受限于大地高H的影响,当H>1 000 km时,其计算误差变大,为了解决这个问题,采用Bowring直接解作为间接迭代法的初值进行求解,实验结果表明,间接迭代法解的精度明显优于直接解的精度,同时不受大地高H的影响。
As the Bowring direct algorithm limited to the impact of geodetic height,when the H is of more than 1 000 km the error with direct algorithm will increase.In order to solve the problem,this paper presents a new algorithm which considers the direct solution as an initial value of the iterative algorithm.The result shows that the new algorithm is sufficiently precise and stable,simultaneously,no longer limited to the impact of geodetic height.
