用LAMBDA改进算法固定GPS整周模糊度

Restricting GPS Integer Ambigulity by Improved LAMBDA Algorithm

  • 摘要: 介绍了LAMBDA算法原理,结合国土资源调查的工程实践,对常规的LAMBDA方法作了两点改进,即扩大超椭球的体积En和以点位的先验信息检验坐标解算结果。实测数据分析表明,两点改进均能有效地提高基线解算的可靠性,具有一定的理论价值。

     

    Abstract: The integer ambigulity is one of the main problems in the GPS solution.On the basis of the theory of LAMBDA method for integer ambigulity estimation and land inventory,two improvements to routine LAMBDA are made.That is enlarging the volume of the ellipsoid and checking the results of coordinate solution by apriori information of the points.Verified by a lot of actual data,the improved LAMBDA algorithm improves the reliability of the base-line solution effectively and has some value in theory.
