## Installation / Debian / Ubuntu / MacOS

```

**1. Clone and run:**
```bash
git clone https://github.com/smittix/intercept.git
cd intercept
./setup.sh
sudo -E venv/bin/python intercept.py
```

### Docker (Alternative)

```bash
git clone https://github.com/smittix/intercept.git
cd intercept
docker compose up -d
```

> **Note:** Docker requires privileged mode for USB SDR access. See `docker-compose.yml` for configuration options.

### ADS-B History (Optional, Postgres)

The ADS-B history dashboard persists aircraft messages and snapshots to Postgres.

1. Enable history and DB connection:

```bash
export INTERCEPT_ADSB_HISTORY_ENABLED=true
export INTERCEPT_ADSB_DB_HOST=adsb_db
export INTERCEPT_ADSB_DB_PORT=5432
export INTERCEPT_ADSB_DB_NAME=intercept_adsb
export INTERCEPT_ADSB_DB_USER=intercept
export INTERCEPT_ADSB_DB_PASSWORD=intercept
```

2. Start the services (includes Postgres in `docker-compose.yml`):

```bash
docker compose up -d
```

3. Open **/adsb/history** for the reporting dashboard and headless start/stop controls.

### Local Fixes Branch (Optional)

If you keep local changes (e.g., custom health checks), use a separate branch and rebase it after updates:

```bash
git fetch origin
git checkout local-fixes
git rebase origin/main
```

### Open the Interface

After starting, open **http://localhost:5050** in your browser. The username and password is <b>admin</b>:<b>admin</b> 

The credentials can be change in the ADMIN_USERNAME & ADMIN_PASSWORD variables in config.py

## Hardware Requirements

| 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).

| :exclamation:  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.

| :exclamation:  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.
