摘要
提出了一种利用多普勒测量量和伪距测量量相结合进行静态三维定位的算法。该算法不仅可以求解用户的三维位置,而且可以求出接收机的时钟偏差和频率偏差。经过进一步的改进,还可以实现对动态用户的定位和测速。文中对所提出的算法模型进行了计算机仿真,仿真结果证明了该算法的正确性及实用性。
An algorithm that can achieve 3D static positioning by Doppler measurement and pseudorange measurement is proposed. Using this algorithm, we can not only achieve 3D positioning but also educe the time error and frequency error of the receiver. 3D dynamic positioning and the velocity of receiver can also be obtained by improving the algorithm further. The validity and practicability of the proposed algorithm have been proved by simulation results.
