摘要
GPS高程拟合在GPS数据处理分析中有着重要的意义。由于采用传统的数学模型进行高精度的拟合较为困难,而基因表达式程序设计方法吸取了遗传算法和基因编程两者的优点,在解决非线性拟合问题方面表现出非凡的数据挖掘能力与优势。为此,在基因表达式编程(GEP)理论分析的基础上,利用该方法建立了GPS高程拟合模型。实验表明,GEP用于GPS高程拟合是可行且有效的。
GPS height fitting has the great important sense in GPS processing since it is difficult to fit more accurate results using the traditional model.The gene expression programming(GEP) method,which extracts the advantages of genetic algorithm(GA) and gene programming,the method shows great promise and capability of data mining in nonlinear fitting.Based on theoretical analysis of GEP,the GPS height fitting model is established.This GEP method for GPS height fitting is feasible and virtual.
