Tracking nearby flights around Ekensberg using SDR to collect ADS-B data and sending online.

Depends on

1. rtl-sdr
2. dump1090
3. python3
4. Docker, Docker-compose

Suggested hardware

Hardware needed is a SDR stick (e.g. RTL2832U from http://www.rtl-sdr.com/), an antenna (an antenna made for 1090 MHz is significantly better, i.e. you will receive more data, than just the standard tv antenna that ships with most sdr dongles) and a computer, tested with OS X, a raspberry pi 1 mod b and a raspberry pi 3.

Get started

Setup osx test environment

Install rtl-sdr using macports (http://www.macports.org/):

sudo port install rtl-sdr

Connect your SDR, e.g. R820T2 RTL2832U, and test rtl-sdr:

rtl_test -t

Install dump1090 (https://github.com/antirez/dump1090):

1. git clone [email protected]:antirez/dump1090.git
2. cd dump1090
3. make
4. ./dump1090 --interactive --net --aggressive
5. Go to http://localhost:8080 and find the data at http://localhost:8080/data.json

Setup raspi test environment

Install rtl-sdr on your raspi:

1. sudo apt-get install -y cmake pkg-config libusb-1.0
2. git clone git://git.osmocom.org/rtl-sdr.git
3. cd rtl-sdr/
4. mkdir build
5. cd build
6. cmake ../ -DINSTALL_UDEV_RULES=ON
7. make
8. sudo make install
9. sudo ldconfig

Make sure no other drivers are loaded for your sdr dongle:

1. sudo vi /etc/modprobe.d/raspi-blacklist.conf
2. Add these lines and save:

blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830

1. Reboot
2. Connect your sdr dongle and test it with rtl_test -t
3. Install 1090 by following the same steps above.

Setup data poster

1. git clone <this repo>
2. Make a copy of .env.sample as .env and fill in exports
3. source .env
4. python -m poster.post_data.py

Setup raspi for Docker

Use a raspi 3 for more punch and built in wifi, probably works with earlier raspis to.

1. Get jessie lite from https://www.raspberrypi.org/downloads/raspbian/ and write to sd-card.
2. Follow e.g this guide http://blog.alexellis.io/getting-started-with-docker-on-raspberry-pi/
3. Install docker-compose following https://github.com/hypriot/arm-compose
4. Add wifi access using e.g. https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md
5. Add your local ssh key:

mkdir .ssh
touch .ssh/authorized_keys
sudo nano ~/.ssh/authorized_keys

1. Fix for local ssh config, so you can ssh pi-name:

Host pi-name
 HostName pi-name.local
 User pi
 PreferredAuthentications publickey

1. Install byobu for easier terminal over ssh sudo apt-get install byobu.
2. Make sure no other drivers are used:

sudo vi /etc/modprobe.d/raspi-blacklist.conf

1. Add these lines:

blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830

1. Get this repo git clone <repo url>
2. Make a copy .env of .env.sample and fill in.
3. docker-compose up
