摘要
为提高船舶姿态实时校正精度,减少船舶姿态校正误差,设计了GPS技术下船舶姿态实时校正方法。首先对船舶姿态校正研究现状进行分析,找到船舶姿态校正误差产生的原因,然后采用GPS技术对船舶姿态进行初步校正,并采用卡尔曼滤波算法船舶姿态进行进一步校正,最后船舶姿态校正实验的结果表明,本文方法的船舶姿态实时校正精度高,船舶姿态实时校正速度快,获得了比其他方法更优的船舶姿态实时校正结果,具有较高的实际应用价值。
In order to improve the real-time correction of ship attitude and reduce the real-time correction error of ship attitude, a real-time correction method of ship attitude based on GPS technology is designed. Firstly, the status of ship attitude real time correction research is analyzed, and the cause of ship attitude correction is found. Then GPS technology is used to correct the ship attitude, and the Calman filtering algorithm is used to further locate the ship attitude. Finally, the experimental results of ship attitude correction show that the ship's attitude correction experiment results show that this method is the ship's ship. The accuracy of real-time attitude correction is high, and the real-time correction speed of the ship's attitude is fast. The real-time correction results of ship attitude are better than other methods. It has high practical application value.
