Abstract: Disclosed are methods, systems and/or devices to calibrate a network time by acquisition of satellite positioning system (SPS) signals and different instances of time, and time-tagging SPS times according to the network time. In particular, the network time may be calibrated based, at least in part, on a first difference between first and second SPS times obtained at two SPS position fixes and a second difference between corresponding first and second time stamps.

Abstract: Techniques for managing power consumption of a Global Navigation Satellite System (GNSS) receiver of a mobile device are provided. These techniques include a method that includes deriving a GNSS search window for the GNSS receiver based on a position uncertainty (PUNC) and a time uncertainty (TUNC), selecting a GNSS search mode based on the GNSS search window and resources available for searching for signals from GNSS satellite vehicles (SVs), wherein an estimated power consumption associated with execution of a GNSS search associated with the GNSS search mode does not exceed a power consumption limit specified for the GNSS receiver conducting the GNSS search using the GNSS search mode, and estimating a position of the mobile device.
