摘要： An attenuated satellite positioning system (SPS) signal is acquired using long integration over multiple navigation data bits. To produce a stable internal clock signal to perform the long integration, an external clock signal is received from a highly stable source, such as a wireless communication base station or a nearby femtocell. An internal oscillator is driven at a desired frequency that is aligned with the scaled frequency of the external clock signal to produce the stable internal clock signal. The SPS signal is received and integrated for an extended period using the internal clock signal. Predicted SPS data may be received from an external source and used to perform coherent integration. Alternatively, non-coherent integration may be performed. Additionally, a motion sensor may be used to determine if there is motion relative to the external clock source or to compensate for Doppler errors in the external clock signal due to motion.

摘要： A mobile station determines a usage pattern based on information stored from previous position fixes. The usage pattern is used to predict a time for a next position fix request. The mobile station performs a position fix in the background prior to the predicted time for the next position fix request. The background position fix provides the precise location and time of the mobile station to place the mobile station in a "hot" state. The prediction of the time for the next position fix request may be affected by the remaining battery power and/or the last known location of the mobile station. Additionally, the difference between the predicted time and the actual time of the next position fix request may be used to adjust subsequent predictions of the time for the next position fix request.
摘要翻译：移动台基于从先前的位置锁定存储的信息来确定使用模式。使用模式用于预测下一个定位请求的时间。在下一个定位请求的预测时间之前，移动台在后台执行定位。背景位置固定提供移动台将移动台置于“热”状态的精确位置和时间。对下一个定位请求的时间的预测可能受到剩余电池功率和/或移动台的最后一个已知位置的影响。此外，预测时间和下一个定位请求的实际时间之间的差可以用于调整下一个定位请求的时间的后续预测。

摘要： An apparatus and method for initiating a search mode of a mobile device including a satelite positioning system receiver based on the light information in the environment of the mobile device is described herein. The light information may include at least one of color temperature or illuminance, which may be used to determine if the environment of the mobile device is indoors or outdoors. A threshold may be predetermined or adjusted based on received position assistance information. The position assistance information may include at least one of time, day, solar angle, motion information, location information, or weather information.
