Build it Yourself ⚙️

Materials List

• 1090MHz Rubber Ducky Antenna
• Raspberry Pi 3B
• FlightAware Pro Stick Plus SDR
• 3.5 in TFT Screen
• Portable Battery Charger
• USB-C to Micro USB Cable
• Custom 3D Printed Case
• SD Card
• Rasbian Operating System
• 4x 3/32 Screws
• Python and Pip on Raspberry Pi

Constructing the Device

1. Install the Rasbian operating system to the Raspberry Pi with the SD Card
2. Connect the Flight Aware SDR to the Raspberry Pi using the Micro USB cable
3. Connect the 1090 MHz antenna to the Flight Aware SDR
4. Configure the 3.5-inch TFT Screen to the Raspberry Pi
5. Place the Device into the 3D Printed Case
6. Ensure Python and Pip are installed on the Raspberry Pi
7. Install dump-1090 FlightAware library on the Raspberry Pi to receive ADS-B information

The following tutorial is very helpful for getting dump-1090 installed on the Pi

Running the Radar Code

Clone the Repository on the Pi

git clone https://github.com/ANG13T/fly-catcher.git

Run the Program

python3 fly-catcher/device-rpi/piawareradar.py longitude latitude

Replace longitude and latitude with your geo-coordinates

Detecting for Spoofing 🔎

Download the Jupyter Notebook

git clone https://github.com/ANG13T/fly-catcher.git
cd notebook
jupyter notebook

Install Jupyter Notebook if you do not have it

Open up the localhost server at http://localhost:8888

Download JSON Flight Logs from Device

Visit the IP address of the Raspberry Pi device followed by the path /data/aircraft.json For example, 192.168.1.114:8080/data/aircraft.json

Open Fly_Catcher.ipynb and Run the Notebook

Future Improvements 🚀

• Enhanced UI features on the radar screen
• Deep learning techniques such as RNNs and LSTM networks
• Incorporating reinforcement learning techniques
• Differentiate spoofing attacks (ie. GPS spoofing, aircraft masquerading, etc)
