| 摘 要： | 针对野外作业对GPS（全球定位系统）快速静态定位的实际需求提出了一种解决方法,该方法不需要进行数据预处理,只需依据DOP（精度几何因子）与定位误差之间的关系及定位点密度与真值可能位置之间的关系计算加权值,并通过加权网格快速求取GPS静态定位点。实际数据测试表明,该方法计算结果优于平均值结果及单一DOP权值和密度权值结果,该方法具有较高的精度和较强的稳定性,并具有准实时的处理时效。

| Abstract: | A GPS(Global Positioning System) rapid static positioning method is proposed to meet field operations demands for GPS rapid static positioning through a weight grid.Without preprocessing,a weight value is calculated based on DOP(Dilution of Precision) and positioning error and the relationship between the density and the true value.Tests with actual data show that the results got with the method are better than average results and single DOP weight or density weight results.Besides higher precision and better stability,the method facilitates quasi-real-time data processing. |
