| 摘 要： | 整周模糊度的正确求解关系到GPS精密定位结果的正确性，搜索法解算整周模糊度的原则是获得目标函数的整数解作为模糊度参数的解，文中分析了各种不同搜索方法构造搜索空间的特性，比较了不同搜索方法对模糊度解算可靠性的影响，即通过搜索，不同的方法能否获得满足目标函数的一组整数解。

| Abstract: | To resolve the GPS integer ambiguity reliably is related to the correctness of the result of GPS high accuracy positioning. The principle of searching method is to fix the integer solution the satisfy the object function as the integer ambiguity. The paper analyzed the character of each method in constructing searching space, and compared different methods' searching reliability, i.e. whether we can get correct solution that satisfy the object function using different method. |
