摘要
根据地面点地心空间直角坐标与地心大地坐标的关系式,导出由空间直角坐标求解大地坐标的更为简洁的直接计算公式,并对计算误差进行分析讨论。理论分析和实际验算结果表明,该直接解法引起的纬度误差不大于10-5s,可以满足精密的大地测量需要。
This paper deduces the simpler direct calculating formula from the relative formulas of spacial rectangular coordinate of point with its geodetic coordinate;analyzes and discusses relative calculating errors.It is proved by the theoretical analyses and the practical caculating results that the latitude error is less than second.This precision can satisfy the need of precision geodetic survey.
