Boeing has a system that does exactly this. (I've played with it - Planet
9 wrote the 3D front end) The main tricky dependency to work around is the
AirNet RapidCell, which is a self contained GSM network in a 4'x4'x4' box.
So so cool but they start at $80k. :(
These two devices both do SMS GPS tracking (I have a benefon sitting right
here, in fact), although that doesn't really help you without the
AirNet...

Hm hm, this is an interesting problem. If you could somehow encode the
SMSes and send them over something incredibly cheap and janky, like those
cheap walkie talkies everyone uses...that'd be something.

I got this email from a fellow burner. Curious what the geowanking community
thinks of it since it's a bit complicated by the
child-cars-cannot-have-computers. What kinds of GPS units are out there that
can transmit their location automatically? I would think the RINO might
work, except I don't think Garmin has an open protocol / system to hack at.

Ok. need to throw together a system to track multiple cars around burning
man from a mobile command car.
Wroking on command car software and hardware now. Have never used GPS at
the playa. Worked a good bit with GPS years ago on robots.
Quick start with command car: (is this acceptable, better ideas?)
1. Purchase NMEA module like the GPS25-LVS.
2. Acquire attenna (any recomendations).
3. Wire up everything.
4. Connect module serially to computer.
5. Write software.
Ok, any flaws with the previous.
No assuming similar computers on the other cars, just need to get the gps
position back to the command car. Good recommendation for PTP serial links
that will span the playa? Maybe a network system (not PTP) like 802.11, then
only one antenna on command center instead of one per client.
Now, for accuracy may need differential. Stationary base station with same
PTP communications to command car.
