单基站CORS-RTK转换参数与数据处理

Data Process and Parameter Conversion in Single-based Station CORS-RTK

依据某城市单基站CORS实测数据,对用不同数目与分布的已知点求解转换参数对模型的内符合精度和外符合精度的影响进行分析;并且提出了采用极大验后滤波进行测量数据后处理,以提高测量的精度。对单基站CORS-RTK的建立和应用具有较先进的指导意义。

In order to establish more suitable single-based CORS station system in middle and small sized cities,depending on practical measured single-based CORS station data in a certain city,this article analyzed the affects from the model to internal accordance accuracy and external accordance accuracy using the mathematical solution converted parameter in a different number and distribution of known points.This study suggests improving the surveying accuracy through ex-process for surveying data by maximum ex-check filter.This method has advanced and directive significance for the establishment and application of single-based CORS-RTK station.
