| 摘 要： | GPS载波相位观测值作为高精度观测量在姿态测量中得到广泛应用。姿态测量系统中，基线长度可以通过提前量测精确求得。作为约束条件，可以用于模糊度搜索，提高模糊度搜索效率和准确度。本文介绍了传统的LAMBDA方法，且在此基础上提出了附有基线长度约束的LAMBDA搜索方法，并比较了两者的搜索效率。

| Abstract: | GPS carrier phase is widely applied in highly precise observation of attitude measurement in which baseline distance can be obtained in advance. As the constraint factor, baseline can be used for ambiguity search to increase the efficiency and accuracy. The paper introduces LAMBDA method and LAMBDA searching method based on baseline constraint. These two methods are compared. |

| Keywords: | integer ambiguity LAMBDA distance constraint of baseline least-square of search constraint |
