摘要 基于单历元模型的理论特点,利用TIKHONOV正则化方法改善法方程的病态性,从而提高模糊度浮点解的可靠性;再结合LAMBDA方法搜索,提高了模糊度浮点解的可靠性及整周模糊度固定的成功率。 On the basis of the features of GPS positioning used to improve the condition of ill-posed normal equation. As is increased. And we improve the reliability of the ambiguity in epoch-wise, TIKHONOV regularization has been a result, the reliability of the ambiguity float solution float solution and success rate of ambiguity integers fixing by combined with the LAMBDA algorithm.
