    Abstract: Methods for: (1) extracting Doppler/velocity measurements; (2) estimating relative clock bias errors; (3) determining range and velocity estimates with associated confidences; and (4) extracting range estimates using channel estimation are disclosed. These methods can be used separately or combined to improve positioning solutions obtained by positioning systems used in indoor locations and other GPS-denied environments.

    Abstract translation: 方法:(1)提取多普勒/速度测量; (2)估计相对时钟偏差误差; (3)确定相关信息的范围和速度估计; 并且(4)公开了使用信道估计提取范围估计。 这些方法可以单独使用或组合使用,以改善通过在室内位置和其他GPS拒绝环境中使用的定位系统获得的定位解决方案。
