Many of us have adopted the APRS protocol for tracking our aircraft: http://www.vansairforce.com/community/forumdisplay.php?f=104 http://www.vansairforce.com/community/showthread.php?t=27773 http://aprs.fi/?call=N399SB&mt=m&z=10&timerange=3600 This is a service in the ham radio two-meter band that already provides GPS location, heading, speed, and altitude. The data is displayed on internet servers that provide real-time monitoring anywhere at no cost. There are some new APRS trackers coming soon that will allow much more data to be transmitted. It will be up to someone to engineer the interface between the aircraft parameters and the tracker, but with engine monitors spitting out a serial stream, this shouldn't be unsurmountable.

The redundance we built in really paid for the seminar many times ov er=2C not to mention the reduce maintenance. His seminar was so valuable=2C our EAA chapter has sponsored his seminars t wics and look forward to doing it again. If you are building or planning to build - I highly recommend attending Bob 's seminar. I have no affilaton with Bob - just a very appreciative builder he helped. Chuck Rowbotham RV-8A built - flying and sold Dave has an RV-9A under construction From: jeschmidt@hotmail.com Subject: RV-List: Nuckoll's seminar June 27-28 RV listers: If you are looking to get some electrical systems education=2C there is sti ll room available at Bob Nuckoll's weekend seminar in Mason City=2C Iowa on June 27 and 28. http://aeroelectric.com/seminars/Mason_City.html It's the best $185 'college tuition' you'll spend. The camaraderie isn't ba d=2C either.
