| 摘要: |
| 研究了模糊度求解的两个阶段，即模糊度估计和模糊度搜索，通过改进的矩阵解耦算法和OMEGA算法，提高了模糊度求解的速度。通过实验证明，在2～3min内就可以正确求解模糊度，并且可以基本达到实时运算。 |

| Abstract: |
| The two stages of the ambiguity solution, ambiguity estimation and ambiguity search, have been researched on. Through the improved matrix decouple method and OMEGA method, the speed of the ambiguity solution has increased. It is proved that ambiguity solution can be made correctly in two to three minutes and computed almost in real time. |
