摘要：
A method of controlling a device that includes a receiver and a movement sensor includes (a) deactivating the receiver； (b) while the receiver is deactivated, analyzing measurements from the movement sensor to determine a measure of the distance the device has moved from a first location； and (c) in the event that it is determined from the measurements from the movement sensor that the device has moved from the first location by more than a threshold distance, activating the receiver and using the receiver to obtain a second measurement of the location of the device.
