RE: [Geowanking] Localized Car GPS System for Burning Man

[Jeremy Irish]

Somewhat easy and cheap: Boost Mobile phone (Best Buy sold it for $45), and http://www.mologogo.com (where you can get the same phone for under $100 – with the right cable!)   They’re adding an interface to allow you to query your location from their site. It isn’t done yet but may be by Burning Man. It also requires a cell phone signal to operate.   Or, alternatively, APRS: http://www.grc.nasa.gov/WWW/MAEL/ag/agaprs.htm And check out findu: http://www.findu.com/   I believe you need a HAM license to do APRS but it is pretty easy to do. I don’t even think a morse code is necessary for the level of HAM radio operator license it requires.   Jeremy   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Longson (nym) Sent: Thursday, March 30, 2006 9:06 AM To: geowanking@lists.burri.to Subject: [Geowanking] Localized Car GPS System for Burning Man   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. Cheers, nym http://igargoyle.com >>>> 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. <<<
