I am looking for some ideas from people on exactly how to go about setting up an APRS network (if that is the best idea)
Here is the setup. I fly model and high power rockets and wish to use APRS from BRBhttp://www.bigredbee.com/BeeLineGPS.htm
The BRB is essentially just a locator.
Next year I will be going to a national launch site that is fairly remote here in Australia
The models are flown and then parachuted back to earth. This could be at altitudes of 20,000 feet or more. Not sure what the wavier will be. So the models coming back to earth on parachutes will have the ability to cover some serious ground before touch down. These GPS locator devices are the Bee Knees lol
There will be a number of other flyers probably using the same gear. I don't know how many could a be a few could be a hundred who knows.
My initial thought is to have a base station at my caravan with an antenna up 10 meters or so to increase range and have everyone use the same freq so that if my base hears the signal it will get repeated to everyone with HT's or other APRS rx. The laptop in the van will plot the location of the various rockets and or the people with APRS enabled radios on a map. This way if anyone hears a signal out walking about looking for rockets that signal will get relayed back to the base and then to everyone else. The other line of thinking is to have everyone on different frequencies that is co ordinated at a board much like the old days of RC airplanes and everyone take care of thier own stuff. I was thinking the whole idea of APRS was to use networking to improve location identification and wanted to go down that route but I can see the thought that packet collisions could impede on getting good data from the rockets. Does anyone have any experience with this sort of thing?
Your thoughts will be appreciated
