METHODS AND APPARATUSES USING MIXED NAVIGATION SYSTEM CONSTELLATION SOURCES FOR TIME SETTING
First Claim
Patent Images
1. A method comprising:
- with a satellite positioning system (SPS) receiver enabled device;
obtaining one or more electronic signals representing partial first system time information, said partial first system time information comprising one or more portions but not all of a first system time identifier associated with a first navigation system;
obtaining one or more electronic signals representing second system time information, said second system time information comprising at least a portion of a second system time identifier associated with a second system; and
generating one or more electronic signals operatively identifying a first system time associated with said first navigation system based, at least in part, on said partial first system time information and at least said portion of said second system time information.

Abstract
Methods and apparatuses are provided that may be implemented in various electronic devices to possibly reduce a first-time-to-fix and/or otherwise increase the performance or efficiency of a device by using portions of system time identifiers from different systems to determine at least one navigation system time.
