基于移除-恢复法的GPS水准高差拟合方法研究

Study for GPS Height Difference Interpolation Based on Remove-Store Method

讨论了将GPS所测的大地高差转换为正常高差的基本原理和算法,研究了移除-恢复法在GPS高差转换中的应用。利用该算法对某线路GPS大地高差观测数据进行处理,结果表明:基于移除-恢复法的GPS高差转换方法能改善高差转换精度,具有较好的实用价值。

The basic principle and algorithm of GPS height difference transformation is discussed in this paper. The application of remove-store method to GPS height differences transform is introduced. Finally some special cases in line shaped railway GPS height differences interpolation are calculated, the results show that the transform method based on remove-store method can improve the precision of height difference transform and have the better practical value.
