Thanks, the GPS would be an option, but in the very secure site I am
working in, I am afraid I will not even be allowed to install an
antenna.

What is the approx cost of such systems?

Do-it-yourself: Under $100 for a Garmin GPS 18 LVC. You also need
a PC. Old ones are probably OK.


For example ..

If his site is really secure, he may have Windows but probably doesn't have windows!!! His electronic equipment may have to meet the "Tempest" criteria; e.g. any electromagnetic energy emissions do not contain recoverable information. Add inner and outer chain link fences topped with barbed wire, armed guards, and dogs. Your imagination can't be to vivid!!!! ;-)
