摘要
介绍了测量中的高程系统及其转换关系,对GNSS水准模型进行了简要介绍。通过实例对山区GNSS水准曲面拟合的精度进行了分析,并对GNSS水准精度和外围点的精度进行了评定,得到了一些有工程价值的结论。
The elevation systems in measurement and their transformation relationship were introduced, andthe GNSS level models were also introduced briefly. The precision of GNSS leveling surface fitting in mountain areawas analyzed through examples, and the GNSS level accuracy and peripheral point accuracy were assessed, andsome valuable conclusions were obtained.
