Build your own ADS-B Ground Station! For free premium FlightAware or FlightRadar service

I like that deal. Is the offer only for Americans, I wonder.

I just happen to have a spare Raspberry Pi. I'll see if I can get this running this evening.

I'm going to to give this a go, as I have everything laying around except the ADS-B receiver. They probably don't need more coverage in the LA area, but real time flight tracking and free enterprise account is great.

As I often try to point out, on "FlightAware"s site (since they use FAA-derived data) there is an approximate 5-minute time delay. Not a "big" problem, usually (AND, I know this from comparing the "LiveATC" audio with FlightAware tracking).

The ADS-B option eliminates this delay.

When I was first introduced to FR24 I followed the USB TV stick hack to get free premium service. Ordered the recommended TV tuner from china (£5) and it works flawlessly. If you got spare cash to spend on the project, I would recommend fitting a decent external antenna for maximum range.

My experience setting this up.

Since I already had a RasPi setup for Wifi, rather than the much easier method of install the disk image I installed dump1090 using the "Script for doing everything at once" from:
http://www.satsignal.eu/raspberry-pi/dump1090.html
Which took over two hours to run - would have been much faster to just re-setup wifi. This is likely because Pi image was old, and the script updated just about everything. At least it was pretty much automated.

Needed to blacklist the kernal drivers:

Then running dump1090 gives the raw stream of data, starting

Code:
[B]pi@raspberrypi[/B] [B]~ $[/B] dump1090/dump1090

Then did "Starting the dump1090 program automatically", from:
http://www.satsignal.eu/raspberry-pi/dump1090.html
(rebooted and ran "top" to ensure it was working).

Now I can connect the Pi directly via the IP address and port 8080, and see the local traffic:

Poor coverage, as it's the default antenna, and indoors. I'll move it to the garage later.

Then installed PiAware using the instructions at:
http://flightaware.com/adsb/piaware/install

Waited less than half an hour for the statistics to update here:
http://flightaware.com/adsb/stats/user/mickwest

And Bingo!


And an important part of doing this, free enterprise subscription!


And I just installed it in a corner of the garage, as high as I could conveniently get it.


Looks like the range is only about 20 miles. Maybe I'll experiment later with antennas.

Oh boy - now that believers know you're feeing data to FR24 they'll KNOW that they're being fed disinfo!!;)

Winner, Winner, Chicken Dinner!!!

Can we ask? About how much investment, in terms of dollars? (of course, you've now provided a bit of coverage for the LA area....something to consider).

And an important part of doing this, free enterprise subscription!
Yes....a very smart investment, indeed!

(I'm not sure I could do this, without inviting the 'Best Buy' "Geek Squad"....).

Also set it up for FR24 data sharing:

wget https://dl.dropboxusercontent.com/u/66906/fr24feed_arm-rpi_242.tgz
tar zxvf fr24feed_arm-rpi_242.tgz
cd fr24feed_arm-rpi_242
./fr24feed_arm-rpi_242 --signup
[Entered info, got sharing key, restarted]

Added a new init.d entry based on the dump1090.sh, changing:
PROG="fr24feed_arm-rpi_242"
PROG_PATH="/home/pi/"
PROG_ARGS=" --fr24key=xxx mykey xxxx"
PIDFILE="/var/run/fr24feed_arm-rpi_242.pid"

Seems to work:

@Mick West

What size SD card did you use?
4GB, it was a setup I had for an old project. Still has 1GB free.

Can we ask? About how much investment, in terms of dollars?
For me, just the cost of the receiver, $24 from amazon
http://www.amazon.com/dp/B009U7WZCA/ref=pe_385040_121528360_TE_dp_1

However I also used a Raspberry Pi ($39), a 4GB SD card ($6) and a USB power supply ($7). I did not use a case, just screwed it to a bit of wood. So total cost would be $76

Edit: Plus a WiFi USB adapter, $9 - optional if you just keep it wired.
