摘　　要：GNSS可用于获取动态载体的姿态信息,为提高其姿态测量精度,提出一种基于基线长度信息对最小二乘姿态解算方法进行加权处理,改进了最小二乘姿态解算方法,同时通过船载实验验证了该方法的可用性。实验结果表明:在船载动态实验中,当基线长度存在明显差异时,加权最小二乘法较等权最小二乘法在精度上明显提高,其中横滚角的精度提高了13%。GNSS can be used to obtain the attitude information of dynamic carrier.In order to improve its attitude measurement accuracy,this study proposes a weighted least squares attitude solution method based on baseline length information,which improves the least squares attitude solution method.At the same time,the availability of this method is verified by shipboard experiment.The experimental results show that in the ship borne dynamic experiment,when there is an obvious difference in the baseline length,the accuracy of the weighted least square method is significantly higher than that of the equal weight least square method,and the accuracy of roll angle is increased by 13%.
