Triangulation

Question:
I would like to know if it is possable to equip a person
with a radio transmitter and determine his location by triangulation and
radio telemetry? The area of the scan would be under 100 meters by 100
meters. But would require the scan to tell whether the person was at
ground level, 10' to 100' above ground and 10 feet below ground level.
The data could be received by a computer.
Replies:
I am not an expert on radio telemetry, but it is possible to locate
someone's position by triangulation; security agencies do it all the time. I
do not know the particular systems that might work in the scenario you
described, but from what you said you may be overlooking a very simple
solution.
There are very good GPS (geographic/global positioning systems) on the
market already that are hand held that will tell you a person's location,
height above sea level, etc. A lot of camping, hiking and other people like
surveyors already use these things in daily life. If you consult a good
outdoor supply place like L.L. Bean in Maine, REI out of Seattle, Erehwon
oufitters, Eddie Bauer, etc. and a host of others, you can find a good hand
held GPS system that may fit what you are looking for (be advised the good
ones are not cheap--at least several hundred dollars). I do not know if the
GPS readouts are adaptable to computer storage, but given the state of
technology today there are probably units that already can do this. If push
came to shove, you can use a GPS system to locate your position and then use
a portable PC that you carry with you (or something like a Palm Pilot
Personal Digital Assistant (PDA) to store the position data that you take
off the read out from the GPS. Just a thought.
