| 摘 要： | 摘要GPS精密单点定位技术已经发展成为GPS领域研究的热点之一。本文主要讨论了：情密单点定位的数学模型、误差处理理论和数据预处理等，并利用Matlab编程进行实验性验证，最终对静态单点：乏位分别采用双频载波相位平滑后的P码伪距组成消电离层组合的最小二乘估计和卡尔曼滤波估计进行处理，得到亚米级的定位结果。

| Abstract: | Precise Point Positioning(PPP) has become one of the hot research area in GPS technology.The paper focused on mathematical models,error processing theory and data pre-processing,and etc.in PPP.With using of Matlab programming for experimental verification,the sub meter static PPP positioning results is respectively got by using the P-code pseudorange,which is smoothed by dual-frequency carrier phase to eliminate ionosphere by Least Squares Estimation and Kalman filtering for processing. |
