Signal statistics dashboard for Mode-S/ADS-B signals from dump1090

dump1090 Real-Time Signal Statistics

This project provides a web application for real-time monitoring of ADS-B messages using dump1090. The application consists of a FastAPI backend and a frontend that displays various statistics in real-time using Chart.js.

Features

• Message Rate Statistics: Computes and displays message rates over different intervals (5s, 15s, 30s, 60s, 300s).
• Signal Strength Statistics: Computes and displays minimum, maximum, and average signal strength over 30 seconds.
• Distance Statistics: Computes and displays minimum, maximum, and percentile distances over 30 seconds.
• Coverage Statistics: Displays coverage statistics in a radar chart, showing the distribution of messages by distance and bearing.

Backend (main.py)

The backend is built using FastAPI and provides the following functionalities:

• WebSocket Endpoint: Handles WebSocket connections to broadcast real-time statistics to the frontend.
• ADSB Client: Connects to a dump1090 BEAST server to receive ADS-B messages, compute statistics, and update sliding windows.
• Statistics Computation: Computes message rates, signal strength, distance statistics, and coverage statistics.
• Broadcast Task: Periodically computes and broadcasts statistics to all connected WebSocket clients.

Running the Backend

To run the backend, execute the following command:

python msgrates.py

Command Line Arguments

The script supports the following command line arguments:

• --host: Host to run the web server on (default: 0.0.0.0).
• --port: Port to run the web server on (default: 8000).
• --antenna-lat: Antenna latitude (required for running the server).
• --antenna-lon: Antenna longitude (required for running the server).
• --dump1090-host: Host running dump1090 (default: localhost).
• --dump1090-port: Port for dump1090 (default: 30005).

Example usage:

python msgrates.py run --antenna-lat 52.5200 --antenna-lon 13.4050

Installation

You can install the program from pip:

pip install signalstats1090

After installation, you can run the program using the following command:

signalstats1090 run --antenna-lat 52.5200 --antenna-lon 13.4050

Frontend (index.html)

The frontend is an HTML page that uses Chart.js to display various statistics in real-time. It connects to the backend via WebSocket to receive updates and update the charts.

Charts

• Message Rate Chart: Displays message rates over different intervals (5s, 15s, 30s, 60s, 300s).
• Signal Strength Chart: Displays minimum, average, and maximum signal strength over 30 seconds.
• Distance Chart: Displays minimum, maximum, and percentile distances over 30 seconds.
• Distance Histogram Chart: Displays the count of position readings in 30km buckets (up to 300km).
• Coverage Chart: Displays coverage statistics in a radar chart, showing the distribution of messages by distance and bearing.
