| 摘 要： | 在详细论述GPS高程转换基本原理的基础上，利用二次多项式模型，对区域高程异常进行了拟合分析，并进行了精度评定。结果显示，利用二次多项式模型进行GPS高程转换能够取得较好的结果，参与建模的点位拟合精度较高，而远离建模点分布区域的点位拟合精度相对较低，建模点的选取能够对GPS高程拟合结果产生重要影响。

| Abstract: | On the basic principle of the GPS height transformation and using a quadratic polynomial moodel,fitting analysis and accuracy evaluation are mde on the regional height anomaly.The results show it get better results using quadratic polynomial model of GPS height transformation.The selection of modeling points has significant impact on the result of GPS elevation fitting.Participation modeling points have higher fitting precision,but the points away from distribution area of the modeling points have lower fitting precision. |
