摘要： A mobile station determines its position using measured parameters of a wireless signal to improve a satellite positioning system (SPS) enhanced dead reckoning based position estimate. The mobile station uses SPS enhanced dead reckoning to estimate a current position. The mobile station receives wireless signals and measures, e.g., received signal strength and/or round trip time, which is compared to a database to derive a wireless signal based position estimate. The SPS enhanced dead reckoning position estimate and the wireless signal based position estimate may then be fused using corresponding confidence levels. The database may be generated and stored in the mobile station. In another embodiment, the database is generated and stored on an online server that may be accessed by mobile stations.

摘要： Methods and apparatus are described herein for calibration and correction of non-constant sensor errors, and in particular non-constant compass errors, that are based in part on changing software and hardware modes of a host device. The non-constant errors induced in the sensor by each mode and combination of modes is determined in a calibration that may be determined during pre-production testing of one or more host devices. The calibration results can be incorporated into software and/or hardware of the host device. During normal operation, a sensor correction can be applied to sensor measurements based in part on the active mode or combination of modes.
摘要翻译：这里描述了用于校准和校正非恒定传感器误差，特别是非恒定罗盘误差的方法和装置，其部分基于改变主机设备的软件和硬件模式。通过每种模式和模式组合在传感器中感应的非常数误差在可以在一个或多个主机设备的预生产测试期间确定的校准中确定。校准结果可以并入主机设备的软件和/或硬件中。在正常操作期间，传感器校正可以部分地基于活动模式或模式组合来应用于传感器测量。
