摘要:
在利用GPS建立各种工程控制网时,为了正确求解坐标系统间的转换参数,须在平面重合点(即原有国家平面已知点)上进行偏心观测.本文从工程应用的实际出发,介绍了一种坐标转移法的GPS偏心观测方法.此法的实质就是在不影响精度的前提下,利用偏心观测数据和三维无约束平差的结果,将平面重合点由真正意义上的已有控制点转移为偏心观测点.工程实践表明,此法不但能满足精度要求,而且简化了外业工作量,具有方便、快捷等优点.
Abstract:
To work out a solution for switching parameter of variant coordinate systems in establishing GPS engineering frameworks, the offset observation is often used in plane-repeat points (i.e.plane control points of nation known). The coordinate transfer method of GPS offset observation is put forward. The essentials of the method regard the offset observation points as plane-repeat points,by using the offset observation data and the result of three dimensional adjustment of free network.Engineering practice indicates that the method assumed is not only accurate enough, but also facile and rapid.
