GPS非线性数据处理的同伦最小二乘模型

Homotopy Least Squares Model of GPS Nonlinear Data Processing

    摘要
  • 摘要: 基于非线性同伦思想,提出了非线性最小二乘同伦方法,并推导出相应的GPS同伦非线性模型和算法。算例表明,对于精度较差的初始值,采用同伦非线性GPS伪距定位模型较线性最小二乘求解精度要好。

     

    Abstract: This paper puts forward the LS adjustment based on the homotopy arithmetic,deduces and constructes homotopy nonlinear LS model and its algorithms with nonlinear LS method.This method is an effective numerical method to solve the nonlinear equation.
