摘要
在介绍GPS水准几何拟合的几种方法和济南市似大地水准面精化建设项目的基础上,以某垃圾处理厂施工控制测量数据为例,对不同几何拟合方法同似大地水准面精化成果所计算的正常高进行了分析比较。根据比较结果和作者经验,分析了GPS高程拟合影响精度的原因及作业中的注意事项,并对本文实验的几种拟合方法的适用范围进行了总结。
Based on the introduction of several methodz of GPS/leveling geometric fitting and Jinan quasi-geoid re. fine construction project, this paper, taking control survey data of a refuse processing plant as an example, analyzes and compares the different geometric fitting methods with the results of Jinan quasi-geoid refine which the results calculated by the normal altitude. According to the comparison results and the practical experience, the present work analyzes the influence factors of accuracy of different fitting methods, and also focuses on the precautions of field survey, Finally the principle of the application scope of these GPS/leveling fitting methods is discussed.
