| Abstract: | At first, this paper introduces the strategy of Bootstrap method of ambiguity-fixing in GPS precise positioning. And then, based on the this, the paper improves the algorithm which can update the two-dimensional normal equations and solution vector and develops a new algorithm which can efficiently update three-dimensional normal equations and solution vector. This algorithm can improve the calculation speed in integer ambiguity resolution and will have certain reference value. |
