Restricting GPS Integer Ambigulity by Improved LAMBDA Algorithm

    Graphical Abstract
    • 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.
