摘要
文章介绍了在城市地方独立坐标系椭球参数及转换参数保密的情况下,在GPS-RTK测量中利用伪七参数和四参数实时获取地方独立坐标的方法,对该流程进行了简要介绍,通过实例对该方法在区域转换的精度进行了分析,得到了一些有工程价值的结论。
The parameter ellipsoid and the transformation parameter in local urban independent coordinate sys- tem are always kept secret. In this paper, a method using pseudo seven parameter and four parameter to acquire real- time local cities independent coordinates was introduced with GPS-RTK surveying, and the model was briefly dis- cussed. Then the accuracy of the conversion using this method was analyzed through the example, and some valu- able conclusions of engineering were obtained.
