GPS高程异常拟合的降维处理算法

A Reducing Dimension Algorithm of GPS Height Anomaly Interpolation

    摘要
  • 摘要: 探讨了基于拟合误差方程病态的降维处理算法,以期得到稳定的解。该方法的本质是截尾正则化算法,并利用实测数据进行了验证。结果表明,本方法非常有效。

     

    Abstract: The unreasonable distribution of GPS leveling height points may cause the estimated parameters unstable,which will accordingly affect the accuracy of the interpolated height anomaly.In order to obtain relatively stable result,this paper probes into a reducing dimension algorithm on ill-posed error equation.Essentially this method is a tailored-regularization algorithm.
