摘　　要：本文提出了一种新的基于大视场光学测量设备和GPS测量点位天文坐标的方法,即测量多个星体方位角相对于主光轴方位角的增量,然后通过非线性最小二乘法解算出点位的天文坐标。采用该方法不仅可以避免讨论大气蒙气差的修正问题,而且能够满足高精度天文坐标的测量要求。A new method for measuring the astronomical coordinate of a location based on optical wide field measurement equipment is discussed in this paper. Firstly we measure the increment of multi-star＇ s azimuth angle from mean optical axis＇ s azimuth angle. Then we can calculate the astronomical coordinate of a location by the method of nonlinear least square. Using this method we can avoid the discussion of the atmospheric refraction, and achieve a higher measuring precision.
