| 摘 要： | 本文简述了利用GPS载波相位技术进行载体姿态确定的原理，比较了目前已有的多种整周模糊度求解算法，选用最小二乘法进行了载体定姿实践，减少了备选整周模糊度的组合数，并采用多种约束信息来剔除不正确的模糊度组合，结合实验，指出了载体姿态变化和整周模糊度搜索速度的关系，提出了一种模糊度确定的辅助方法，并给出了应用算例。

| Abstract: | The principle of attitude determination based on GPS carrier phase has been introduced. The Least Square Method has been selected for the application example after analyzing and comparing several algorithms for GPS integer ambiguity resolution. Combined with several kinds of constraint information, this method rejects the incorrect integer ambiguity. The actual calculation example shows the relationship between the attitude change and the ambiguity searching speed. An effective auxiliary method of ambiguity res-olution has been presented based on the example. |
