| 摘 要： | 利用GPS载波相位测量可以精确确定两个载体间的相对距离，其核心问题是整周模糊度的快速求解，通过双频数据可以提高模糊度求解的速度。在推导模糊度组合的一般公式的基础上，研究了一种基于双频GPS接收机模糊度快速求解算法。实验证明该方法正确有效。

| Abstract: | Using the GPS carrier phase measurement,the relative distance between the two carriers can be surveyed accurately. The kernel problem is the resolve of the integer ambiguity. Through the dual frequences data, the speed of the resolve can be improved. Based on the derivation of ambiguity combination formula, this paper introduces one method which can resolve ambiguity rapidly and exactly using dual frequence GPS receiver. It is proved that this method is verified by experiments. |
