摘要
高程测量的方法较多,其中精度最高的是几何水准测量,但是几何水准测量的工作量大,因此在困难地区多采用GPS高程拟合的方法。本文采用多种GPS高程拟合算法进行计算,经试验成果的比较、分析,GPS高程拟合在某地区可以达到四等水准测量的精度要求,能够解决该地区四等水准测量需求。
There are many methods for measuring elevations, of which geometric leveling is most precision, but its workload is high, so GPS elevation fitting is more popular in difficulty areas. This paper applied many GPS elevation fitting algorithms to calculation, by comparing and analyzing test results, concluded that GPS elevation fitting can meet fourth-grade leveling precision.
