Xes and others, I have at long last successfully built dump1090 on my Ubuntu system. Dump1090 is ADS-B air traffic controllers radar view app for the cheap SDRs we are using.
The dump1090 build instructions from here most importantly including a new build of rtl-sdr which is apparently a dep for the build http://www.hfunderground.com/wiki/RTL-SDR compile went fine and after I rmmod dvb_usb_rtl28xxu dump1090 runs and picks up updating aircraft IDs and locations but when I try to use the localhost:8080 web GUI I get the file gmap.html does exist and I can open it by pointing my browser at it though it doesn't show any aircraft despite them being listed in the --interactive list in terminal. I suspect a permissions problem, my old bane, as to even cd to /root/git/dump1090 is permission denied unless I am sudo su
If I can get this to work on Ubuntu then next step is another attempt at scratchbox.
What makes dump1090 so cool is despite the small screen of the N900 someone can take the dumbest tablet capable of using bluetooth PAN/DUN or WiFi ad-hoc to display the ADS-B plots on any web browser, compare to $900 for this http://www.sportys.com/PilotShop/product/17996 I suspect it contains a RTL-SDR and a RasberryPi, wonder if we can squeeze the GPL stuff from them?
Apparently there is also a way to rx and decode nexrad radar weather and NOTAMs near an airport.
Of interest in the future as 978mhz ADS-B transponders become common on light aircraft we will probably need to run two SDR modules to cover both th big and small aircraft freqs.
