Through the use of Amateur Radio and
the Automatic Position Recording System (APRS), you can now find
where I am at any given moment. By clicking the link and scrolling down
the page, you will be shown the detail for where Computer Care is located.
If we're on the way to your location,
sitting in the street, still at the last customer stop, or next door. The
maps will show you.
APRS works by linking a GPS (Global
Positioning Satellite receiver) and small interface box and an amateur
(ham) radio. As the GPS gathers information, it sends that data thru the interface
box, and then to the radio where it is transmitted on 144.39 Mhz. There
are APRS repeaters which pick up the signals and transfer them to
the Internet or other APRS repeaters. This is just the basics of how it
works.
APRS can be used for many things
such as tracking a vehicle location. Why would you want to do this? One
example is a portable APRS station could help search and rescue teams coordinate
their searches. Another could be placing one at the end of a bicycle race
to track where the very end of the race is, or the beginning. Or to track
where your local computer service person is (me). And many other uses.
