Claim:
1. A method for managing power consumption of a Global Navigation Satellite System (GNSS) receiver of a mobile device, the method comprising: deriving a GNSS search window for the GNSS receiver based on a position uncertainty (PUNC) and a time uncertainty (TUNC), the PUNC being determined at least in part by sensor data indicating whether the mobile device is stationary or has moved less than a predetermined threshold distance from a last known position; 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 based at least in part on results of the GNSS search.
