| 摘 要： | 针对现有的多种周跳检测与修复、整周模糊度求解算法以及单纯GPS测姿和单纯惯导测姿的优缺点,提出了一种适合船舶姿态测定的方案。该方案结合平差原理和多普勒信息处理周跳,并对LAMBDA算法进行了改进和优化,采用多种约束信息来剔除不正确模糊度组合,最后采用基于Kalman模型进行陀螺与GPS航向角数据融合。实验结果表明,在0.497m基线条件下,航向角精度优于0.3°,俯仰角(横滚角)测量精度优于0.5°。

| Abstract: | Pointing against a variety of existing slip detections repair,ambiguity algorithms,as well as pure and simple inertial navigation system GPS attitude determination of the advantages and disadvantages of attitude measurement. The program combines adjustment theory with Doppler information to process slips and to do a certain amount of improvement and optimization to LAMBDA algorithm,supported by a variety of constraints information to remove incorrect ambiguity combination,and finally,based on Kalman model, ... |
