AlwaysOnGPS is a new Windows Mobile application that lets those who have a GPS system determine their location in places where GPS signals are not available.
To do this, it uses the handheld’s Wi-Fi capabilities to make a map of an area. After this has been completed, AlwaysOnGPS can supply coordinates based on the Wi-Fi map if GPS signals aren’t available.
This isn’t a substitute for a regular GPS system; it is a supplement, and, of course, the Pocket PC must have Wi-Fi functionality.
Potential customers should also be aware that AlwaysOnGPS is of no help when visiting a new area. It needs a day or so to create its map of Wi-Fi signals before it can help fill in for missing GPS signals.
It is intended primarily for people who live in cities where GPS signals are frequently obscured by tall buildings, but there are plenty of Wi-Fi access points.
This application is available on the AlwaysOnGPS web site for $19.95.
A 30-day evaluation copy is also available.
