| 摘 要： | 针对试验舰质心确定困难问题,提出了一种基于定位和姿态数据的试验舰质心确定方法。通过建立试验舰姿态与传感器中心诱导升沉的关系,推导出了试验舰锚泊状态下质心在船固坐标系中位置的解算模型。实验结果表明,采用本方法进行试验舰质心确定不需添测深仪以外的设备,确定的试验舰质心具有较高的精度,能明显地提高舰载无人飞行器惯导对准效率。

| Abstract: | In this paper,a method of determination of the centroid of test vessels is proposed.Through the relationship construction between the vessel attitude and the induced heave of the GPS-RTK,the position of certroid in the hull oriented coordinate system is obtained under static state.The simulated results show that the calculations are consistent well with the true values of vessel certroid and the new developed approach works well.The method can also improve the initial alignment efficiency of unmanned aerial vehicle. |
