| 摘 要： | GPS RTK测量时,首先要求解WGS-84坐标与国家或地方坐标的转换参数,针对小区域地区四参数转换过程进行简化,对其进行验证,同时与目前使用的方法进行比较,发现在相同的条件下,此简单过程解算的参数解算精度略好,最后探讨使用该方法时,采集公共点WGS-84坐标的观测误差对坐标转换参数精度的影响,对更加方便操作RTK有指导作用。

| Abstract: | The coordinate transformation parameters between WGS-84 and the national or local coordinate should be calculated first when measuring GPS RTK.Aiming at the four-parameter conversion process of small regional areas,a simplified method was put forward and validated.It was found that the precision of this simple method was slightly better than the other means currently used when compared in the same conditions.Finally,when applying this method,the impact of the observation error of WGS-84 common point collection on the precision of coordinate transformation parameters was discussed,which had an instructive role in more conveniently operating RTK. |
