【摘要】：根据方位基准计算的理论和多年的经验,梳理了方位基准的计算过程,梳理内容包括计算公式和精度估计;然后利用20组实测数据,利用拉普拉斯方程和大地主题反解计算控制点以及方位点间的大地方位角差值,符合在2″内;最后在不同条件下需要选择合适的方法计算大地方位角,对日后计算方位基准具有一定的参考价值。
[Abstract]:According to the theory of azimuth reference calculation and years of experience, the calculation process of azimuth datum is combed, and the contents include calculation formula and precision estimation. Then, using the 20 sets of measured data, using the Laplasse equation and the Earth Theme reverse solution calculation control point and the azimuth difference between the azimuth points, it is in the 2 "; finally, it is not. Under the same conditions, it is necessary to select the appropriate method to calculate the large local angle, which has a certain reference value for the future calculation of azimuth datum.
