Ah, thought this might be the case. Then yes, seems like limited to a good Wifi connection, probably provided by a up-powered LinkSys WRT54G basestation on the command vehicle and/or base stations. There is this OpenTracker (http://n1vg.net/opentracker/) which uses APRS and serial GPS, though APRS does require Amateur HAM callsign to use. Another commercial option is the kenwood TH-D7AG (http://www.kenwood.net/indexKenwood.cfm?do=ProductDetails&ProdID=5018&Group=5) > On 3/30/06, Andrew Turner <[EMAIL PROTECTED] > wrote: > > > Well, if you're not hooked into a single "unit", then buying a BT GPS > unit and a Nokia BT phone w/ internet connection or SMS.
