在GNSS单频姿态测量技术中，利用单差载波相位和码相位结合模型以及CLAMBDA算法(带有基线约束的最小二乘降相关平差算法)解算整周模糊度可以达到较好的定姿结果，但解算成功率不高。针对这一问题，提出了一种多基线三角形约束的递推多历元方法。三角形基线约束主要针对副基线，利用它可以使CLAMBDA算法得出的整周模糊度更准确。而递推多历元则保证了在此时刻没有解出整周模糊度时仍然可以计算出姿态角，主、副基线都适用。2种方法结合，进一步提高了姿态解算的成功率。对副基线的解算进行了验证，实验证明，这种方法将副基线的成功率提高到99.7%以上。

In the technology of the global navigation satellite system ( GNSS ) single frequency attitude determina-tion, the single-differenced carrier phase and code phase combination model and the CLAMBDA method were used to estimate the integer ambiguities. In this way, the success rate of GNSS attitude determination can be improved to a certain extent, but there is still room for improvement. In order to solve this problem, a multiple-baseline triangu-lar constraint recursive multiple-epoch method was presented for improving the success rate of attitude determination farther. Triangular constraint is mainly for the secondary baseline, and can be used to make the integer ambiguity resolution more accurately. The recursive multiple-epoch ensures that the attitude angle can still be calculated when the integer ambiguity of this moment is unknown. It can be used for not only the main baseline but also the second-ary baseline. The testing results show that the proposed method can improve the success rate of attitude determina-tion for the secondary baseline to more than 99 . 7%.
