摘　　要：提出了利用C／A码单频相位和伪距观测数据进行动态单点定位的方法，并给出了相应的Kalman滤波方程。动态和静态试验结果表明，采用本文介绍的导航定位算法可使单频GPS接收机达到较高精度的动态和静态定位结果。The method of dynamic point positioning based on single - frequency phase and pseudorange is pre - sented and the corresponding state equation and observation equation of Kalman filtering is given. The calculation of dynamic and static experiments shows that the meter level point positioning precision of single - frequency phase and pseudorange can be obtained by adopting the new method.
