摘要
提出了一种利用3颗卫星进行三维定位的算法。该算法在利用现有GPS接收机硬件的条件下,既可以求解用户的三维位置,还可以求出接收机的时钟偏差和频率偏差。对算法模型进行了原理推导,并在此基础上进行了计算机仿真。试验结果证明了该算法的正确性及实用性。
An algorithm that uses only three satellites to achieve 3D positioning is presented. The new algorithm can be implemented on a GPS receiver without changing its hardware. The theory of the algorithm is given mathematically and then the simulation results are given. It can be seen that the algorithm can satisfy practical use.
