My little page on Geocaching/GPS/etc
The GPS is a very useful tool. There are many applications for these things. Geeks and non geeks alike enjoy Geocaching, a sort of GPS based treasure hunt game. Hams use GPS for the APRS system, which communicates their location and messages via packet radio. Smart missles use it to find the right shack in the middle of wherever to blow up. OnStar uses it to determine the location of your vehicle to get help on its way. Drivers use it to navigate unfamiliar roads or determine how long til the next gas stop.
