摘要 研究单频GPS精密单点定位的算法,包括单频精密单点定位的回归方程及卡尔曼滤波用于单频精密单点定位。探讨卡尔曼滤波的观测方程和状态方程,给出状态转移矩阵及系统噪声矩阵。通过算例验证在1s采样率的情况下,定位达到了分米级的精度。 It presents the algorithms of single-frequency GPS precise point positioning, including the regression equation of single-frequency precise point positioning and the Kalman Filter for single frequency precise point positioning. The observation equation and the equation of state of the Kalman filter are analyzed, and the state of the transfer noise matrix and system matrix are given. Through the example the position reaches to a decimeter-level accuracy in the 1 second sampling rate.
