Low-energy GPS
This document describes various techniques for implementing low-energy GPS on a mobile device. A GPS module is activated, a sub-millisecond pseudo-range estimate is received from the GPS module, the GPS module is deactivated, the sub-millisecond pseudo-range estimate and a time stamp are transmitted to a remote entity, and location information based on the sub-millisecond pseudo-range estimate and time stamp is received from the remote entity.
