摘　　要：为了提高GNSS姿态测量系统的精度和可靠性,提出一种适用于多天线姿态测量的3维无约束平差方法:通过一组基于4天线构型的GPS/BDS多频单历元静态实验,将所有的基线作为观测量整体进行3维无约束平差;并将平差前后的基线结果与利用平差前后的基线进行姿态角解算的结果分别进行对比。实验结果表明,在基于4天线构型的姿态角解算过程中,不论GPS还是BDS,使用这种平差方法都可使精度和可靠性指标有所提高。In order to improve the accuracy and reliability of GNSS attitude measurement system, the paper proposed a three-dimensional non-constrained adjustment method for multi-antenna attitude measurement： through the GPS/BDS multi-frequency single-epoch static test based on the four-antenna configuration, all the baselines was taken as the whole concept of measuring to be adjusted by the three-dimensional non-constrained adjustment; and the final results of the baseline before or af-ter adjustment and the attitude angles solved by both baseline results before or after adjustment were compared respective-ly. Result showed that using the adjustment method for the attitude determination of both BDS and GPS based on four-antenna configuration, the accuracy and reliability could be improved efficiently.
