| 摘要: |
| 以GPS载波相位测量来确定载体姿态为背景，针对其中的关键技术问题——载波相位整周模糊度的快速解算,提出了一种充分利用卫星与基线之间几何约束来压缩搜索空间,快速得到正确的双差模糊度组合的方法，并通过对ADUⅡ接收机采集的原始数据进行处理，其结果证明这是一种行之有效的模糊度搜索方法。 |

| Abstract: |
| On the basis of application of GPS carrier phase measurements to determinate the carrier's attitude, focusing on its key technical problem—fast determination of carrier phase ambiguity,a method which makes full use of geometric constraints among GPS satellites and baseline to compress search space in order to acquire the correct double differential ambiguity quickly has been developed. A simulation experiment using the rude statistics received by ADUⅡ attitude determination receiver shows that it is a practical ambiguity resolution. |
