Not sure what to do with timing yet, most of the time we'll have no more than 5 vehicles to track, at Mid Ohio I could have up to 12-15. Just to clarify for everyone, you are not tracking race cars, but the emergency support vehicles. When in action, 30s is far too slow, but I dont see how 5 vehicles could xmit updates every 5 seconds without lots of collisions. If you set up SmartBeaconing to update rapidly when the vehicles are responding, you would be able to keep the dormant response vehilce out of your way on RF because they are not sending position reports. Because SmartBeaconing is activated by movement input, there is no way to avoid collisions. You will want to use the shortest possible packets, and you will want the highest possible precision as well. The 60 foot grid precision won't cut it, you'll need the 2 to 3 foot precision. Here I'll save time ans simply quote Curt: Mic-E: No timestamp and about 60' precision, short packets. Standard APRS: Timestamp and about 60' precision, longer packets. NMEA: Timestamp and precision based on GPS sentence but LONG packets. Base91: Timestamp and 2' precision (assuming GPS puts out good precision), short packets. So, what are you using for trackers? Going to 9600 baud also shortens up the packets, but it limits the available tracker hardware.

Either set them up for SmartBeaconing with parameters that make then transmit fast enough for you, which will allow them to somewhat randomly change their timing as they go, or set them up for timeslotting. Unfortunately I think most of the trackers out there aren't set up to transmit more often than once per minute using timeslotting. BTW: Some collisions are ok. Don't expect to get every transmission. If you set them up for non-timeslotting as in a regular timed transmission or SmartBeaconing, set them up so that you have a enough free time for all of them to transmit, plus double or triple. You'll get some collisions for each, but you'll get a lot of positions out as well. Hopefully that made some sense. I doubt you're going to get updates every 5 seconds unless you're running only one or two cars. You may be able to get as fast as 2 seconds per transmission, across all the cars, so if you have 10 cars you might be able to get 20 second updates per car. To get each one transmitting in the clear you'd probably require custom mods to the OpenTracker firmware, but Scott would know. If you just have each car transmitting every 20 seconds with fixed-timing (not timeslotting), then you have the chance of collisions and you may not get updates for 40 seconds, or 60, or even longer, from any particular car. Another way to avoid this is to have each car on a separate frequency, then base can have multiple receivers (a separate scanner or radio per frequency) and get all of them in the clear. Xastir can handle that just fine, but you'd need a separate TNC per scanner or radio, as the soundcard driver (AGWPE) would only be able to handle two radios. If you had a system that was capable of handling multiple soundcards, then _perhaps_ AGPWE could be run on each one of them, giving you two radio channels per soundcard.

On Sat, 18 Nov 2006, Jeff Mohler wrote: > Ya..that thought hit me at dinner..just have to get a second base radio. ;) Another thought that has been crossing my mind while reading this thread is that if you try to run both the tracking and voice comms on separate VHF frequencies to the cars, you'll end up with desense problems on the voice channel. The VHF frequencies would need to be separated by quite a few megahertz in order for this effect to be reduced or eliminated. I say this because this could become a serious safety issue if the car cannot hear you due to its tracker transmitting often and/or cars near it doing the same. Same for base, if you have cars zipping by near base then the base radio voice frequency may not be able to hear much while any of the trackers nearby are transmitting. The easiest way to get around that is to transmit on a different band entirely, like perhaps using GMRS radios (require $80/five year license), MURS, etc. I experience this desense of my voice rig on 2-meter VHF ham radio (at 146.92 MHz) when my other 2-meter VHF radio on 144.39 MHz decides to send out my position. I use Base-91 compressed transmissions so they are short, but I still can miss one or two syllables on voice during that time. Combine that with 15 or 20 trackers on a small course and the voice frequency might be unusable for you if it's on the same band. -- Curt, WE7U. archer at eskimo dot com http://www.eskimo.com/~archer Lotto: A tax on people who are bad at math. - unknown Windows: Microsoft's tax on computer illiterates. - WE7U.

If using AGWPE on Windows, make sure you test it all out and also that your audio mixer settings get saved/restored properly. This will hopefully make the portable setups nice and reliable for decoding packets. -- Curt, WE7U. archer at eskimo dot com http://www.eskimo.com/~archer Lotto: A tax on people who are bad at math. - unknown Windows: Microsoft's tax on computer illiterates. - WE7U.

Scan down to where it says: [ ] Edit Shapelib's Makefile to remove the space after the "-h" on the line that looks like this: It specifically mentions that issue. Also, you can just use the "get-maptools.sh" script described towards the end of the shapelib section, which will take care of all the arcane junk that has to happen. > But..before I get too far, is this going to work with any manner of > soundmodem or method to get data from a VHF radio into xastir on > cygwin? Yes. It works with AGWPE. You'll have to download it and get it working yourself according to its various well-written documentation, but once you do have it working xastir can connect to the running AGWPE and use it as a TNC. > On 11/18/06, Tom Russo <[EMAIL PROTECTED]> wrote: > >On Sat, Nov 18, 2006 at 02:26:06AM -0800, we recorded a bogon-computron > >collision of the <[EMAIL PROTECTED]> flavor, containing: > >> > >> But I'd like to use Windows as the base OS, just that I keep trying to > >> find a comprehensive set of Cygwin install instructions where all of > >> the steps still work today in 2006.

Thanks Tom..I kept going straight to other instructions..and didnt get into -that- document far enough. Fantastic. Im trying to add shapelib via the instructions and get this error in 'make lib': /usr/bin/ld -G -h libshp.so.1 -o .libs/libshp.so.1.0.1 shpopen.lo shptree.lo dbfopen.lo -lc dbfopen.lo: In function `DBFReadAttribute': /cygdrive/c/Documents and Settings/jmohler/src/shapelib/shapelib-1.2.10/dbfopen.c:716: undefined reference to `__getreent' /cygdrive/c/Documents and Settings/jmohler/src/shapelib/shapelib-1.2.10/dbfopen.c:724: undefined reference to `__getreent' make: *** [lib] Error 1 Thanks for any assistance. :) But..before I get too far, is this going to work with any manner of soundmodem or method to get data from a VHF radio into xastir on cygwin?

[Xastir] New user..and thanks..
Ive spent the last week looking at the different OS's and ways to use Xastir. But here is where im at today.. My goal is a graphical system that can track via GPS our safety vehicles at racetracks in CA. My test has to be up and working for pace car at our 25hr endurance race here: http://www.nasa25hour.com/ ..so Xastir appears to be a good method to create a custom map, and track this one vehicle as a dry run, then build this up to tracking 15 vehicles in February. Fedora linux isnt a bad option, but very unsupportable for the end user im building this for...and mind you im -very- new to Xastir/APRS/etc. But I'd like to use Windows as the base OS, just that I keep trying to find a comprehensive set of Cygwin install instructions where all of the steps still work today in 2006. (Picky eh?) That seems to hold the most hope in reducing complexity in code & compiling to get a system where I can view maps, and _create_ maps. How much creativity do I have available to me to create a custom map? As for the data, I will be using opentracker using our 2-way VHF radios (spare ones) on a separate channel from voice to transmit data, and a base radio with audio output to the windows sound card to input with Soundmodem for windows..the data. Am I on the right track? ___ Xastir mailing list Xastir@xastir.org http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
