摘要
根据海道测量对姿态传感器安装位置以及观测点姿态改正对质心坐标系的要求,提出了一种利用GPS-RTK测量技术确定测船质心位置的方法,并给出了静态锚泊情况下测船质心位置的确定模型。实验结果表明,该方法能够以较高精度求定测船的质心,适用于海道测量船质心位置的确定。
In terms of the attitude correction of the sensors position in hydrographic survey, determination of the barycenter of the surveying boat accurately is necessary. Based on the RTK technique, a new method for determination of the barycenter of the surveying boat is presented and a series model is developed under static state. The simulated results show the calculations and the true values are in a good consistency. The validation and reliability of the new developed approach is verified. The error of the barycenter position of the surveying boat determined by the observation including RTK noise level can also be neglected.
