随着云计算和物联网的发展，电子设备对高精度相对位置的需求也日益增加，传统的相对定位算法假设卫星信号到达基准站和移动站是平行的，随着基线长度的增加定位算法会产生较大误差。针对上述问题，根据卫星信号到达基准站和移动站的情况，提出了一种基于三角形的相对定位算法，该方法利用三角形代替传统方法的平行线，利用余弦关系构建单差方程，进一步利用牛顿迭代对方程进行优化求解。仿真结果表明，在长基线的情况下论文所提方法仍可实现高精度定位，克服了传统方法的定位误差大的缺点，在军事和民用领域具有一定的应用价值。%With the development of cloud computing and networking , electronic devices demand high precision rel -ative positioning.The traditional relative localization algorithm assumes that the directions of satellite signals which reach the base station and rover station are parallel ; its error increases with increasing length of baseline .To ad-dress the problem, we discard the “parallel” assumption and proposed a relative localization algorithm that is based on the triangle in Fig.2 of the full paper, whose three vertices are the satellite, the base station and the rover sta-tion; the proposed algorithm uses the cosine relationship to establish a single difference equation and then uses the Newton iterative equations for obtaining the optimal solution .The simulation results and their analysis show prelimi -narily that the proposed method can still achieve high -precision positioning in the case of long baselines .
