Electronic – the GPS Hotfix Feature


I'm finding that some GPSs (e.g. Garmin nĂ¼vi 2300) have a "HotFix" feature that causes satellite connections to be made more quickly.

How does this feature work? Is it internet/WiFi-based, is it similar to WAAS, or is it something else?

Apparently, the GPS predicts the future positions of satellites.
