| 摘 要： | 差分GPS水下立体定位系统通过测量目标到两个浮标的距离差来进行空间定位,由于这种双曲线定位模型在进行迭代计算时容易发散,所以本文根据空间浮标和目标的空间几何关系,提出了一种空间双曲线交会的直接算法,该方法能够直接求解目标点的空间坐标,且不存在定位结果的发散问题。

| Abstract: | Under-water GPS positioning system uses distance difference between two ranges from target to GPSbuoys to resolve the target's position. It's very easy to make positioning algorithm diverse by hyperbola's intersection. In this paper, an analyticgeometry algorithm is given in details , which is based on space geometric relationship between the target and buoys. The coordinates of target are directly resolved by analyticgeometry algorithm, which is a good measure to overcome the diverse problem of hyperbola intersections. Some results and conclusions are shown in the end. |
