| 摘 要： | 在分析单频GPS精密单点定位的自适应滤波模型的基础上,采用局部误差探测、诊断和修复的方法修复周跳,剔除野值。对于机动加速度,利用自适应因子从整体上调节状态预报信息的协方差矩阵。利用自编软件计算实测数据,并分析该模型的精度。结果表明,采用附加模糊度参数的Kalman滤波法可达到单频亚米级的动态定位精度。

| Abstract: | The adaptive Kalman filtering for single-frequency PPP is described in this paper.The quality control method DIA is used to detect the cycle slips and outliers.A testing example calculated by the software developed by the author is used to analyze the accuracy of the proposed model.It can achieve a sub-meter accuracy using adaptive Kalman filtering with single frequency observations. |
