Abstract: Techniques for improving positioning performance using categorization of navigation signal environment are described. A mobile device can receive signal environment data. The signal environment data can represent multiple geographic areas. The signal environment data includes a respective signal environment category for each geographic area, each signal environment category corresponding to a degree to which geographic features in the respective geographic area affect reception of the navigation signals. The mobile device can determine that the mobile device is located in a particular geographic area represented in the signal environment data. The mobile device can then select a set of one or more rules for aiding location estimation. The set of one or more rules can correspond to the signal environment category of the geographic area. The mobile device can estimate a location of the mobile device using the navigation signals and under the set of one more rules.

Abstract translation: 描述了使用导航信号环境分类来改善定位性能的技术。 移动设备可以接收信号环境数据。 信号环境数据可以表示多个地理区域。 信号环境数据包括每个地理区域的相应信号环境类别，每个信号环境类别对应于相应地理区域中的地理特征影响导航信号的接收的程度。 移动设备可以确定移动设备位于信号环境数据中表示的特定地理区域中。 移动设备然后可以选择一组一个或多个规则来帮助位置估计。 一个或多个规则的集合可以对应于地理区域的信号环境类别。 移动设备可以使用导航信号并且根据一组多个规则来估计移动设备的位置。
