Signal Intelligence Platform
A web-based interface for software-defined radio tools.
- Pager Decoding - POCSAG/FLEX via rtl_fm + multimon-ng
- 433MHz Sensors - Weather stations, TPMS, IoT devices via rtl_433
- Aircraft Tracking - ADS-B via dump1090 with real-time map and radar
- Vessel Tracking - AIS ship tracking with VHF DSC distress monitoring
- ACARS Messaging - Aircraft datalink messages via acarsdec
- Listening Post - Frequency scanner with audio monitoring
- Satellite Tracking - Pass prediction using TLE data
- ADS-B History - Persistent aircraft history with reporting dashboard (Postgres optional)
- WiFi Scanning - Monitor mode reconnaissance via aircrack-ng
- Bluetooth Scanning - Device discovery and tracker detection
- Spy Stations - Number stations and diplomatic HF network database
**1. Clone and run:**
```bash
git clone https://github.com/smittix/intercept.git
cd intercept
./setup.sh
sudo -E venv/bin/python intercept.py
git clone https://github.com/smittix/intercept.git
cd intercept
docker compose up -dNote: Docker requires privileged mode for USB SDR access. See
docker-compose.ymlfor configuration options.
The ADS-B history feature persists aircraft messages to Postgres for long-term analysis.
# Start with ADS-B history and Postgres
docker compose --profile history up -dThen open /adsb/history for the reporting dashboard.
After starting, open http://localhost:5050 in your browser. The username and password is admin:admin
The credentials can be change in the ADMIN_USERNAME & ADMIN_PASSWORD variables in config.py
| Hardware | Purpose | Price |
|---|---|---|
| RTL-SDR | Required for all SDR features | ~$25-35 |
| WiFi adapter | Must support promiscuous (monitor) mode | ~$20-40 |
| Bluetooth adapter | Device scanning (usually built-in) | - |
| GPS | Any Linux supported GPS Unit | ~10 |
Most features work with a basic RTL-SDR dongle (RTL2832U + R820T2).
| ❗ Not using an RTL-SDR Device? |
|---|
| Intercept supports any device that SoapySDR supports. You must however have the correct module for your device installed! For example if you have an SDRPlay device you'd need to install soapysdr-module-sdrplay. |
| ❗ GPS Usage |
|---|
| gpsd is needed for real time location. Intercept automatically checks to see if you're running gpsd in the background when any maps are rendered. |
