The GPS link Doug had is a GPS locator for a PC. The software is ment to give the PC user a location. I tried and returned one like it. Was slow to work and was not accurate to show the corect street you are on.

One idea is to put a cell phone with GPS tracking with the equipment. Nextel has GPS on all their phones and offer an online tracking map to the phones last fix. If you sign up to a basic plan with almost no minuits and the GPS service. They might give you a bottom line phone free. The problem is you would have to keep charging the phone, baterys, leave the charger pluged in, or ??. Can't say how well the GPS would work if it is in a metal case.
