| 摘 要： | 给出了GPS水准拟合中的加权综合模型和混合拟合模型,通过某测区的GPS水准数据对该两种综合模型和几种单一模型进行了计算和比较分析,结果表明综合模型逼近高程异常的精度和可靠性均高于单一模型,并且混合拟合模型比加权综合模型理论上更为合理。 |
| 关 键 词： | GPS水准 高程异常 曲面拟合 综合模型 |

| Abstract: | Two combined models which are weighted combining model and hybrid fitting model in GPS leveling are discussed.Then we employ the two combined models and some single models,such as conicoid model,polyhedral function model,shepard curved surface model are used in approximating height anomaly in a test area.The results indicate that the precision and reliability in approximating height anomaly by combined models are better than any single model that are referred above,and the hybrid fitting model is more reasonably than weighted combining model in theory. |
| Keywords: | GPS leveling height anomaly curved surface fitting combined model |
