A short tour of the live map, flight history, route replay, comparisons, and alerts.

The story

What I wanted to explore

I wanted to combine a Raspberry Pi and radio receiver with software I built myself, then turn aircraft broadcasts into something I could explore through a browser. The project began with live tracking and grew into flight history and statistics, with alerts and AI-assisted queries planned as later steps.

What it delivers

A 1090 MHz antenna and RTL-SDR receiver feed aircraft broadcasts to a Raspberry Pi. A Java service processes the observations, stores flight data, and serves a React dashboard with live positions and history. Planned work includes geofence alerts and natural-language queries over the recorded data.

At a glance

Live radar
Follow aircraft positions received through my own antenna and ADS-B receiver, rather than an external flight-tracking feed.
Flight history
Review recorded flight sessions and compare aircraft by speed, altitude, or distance from the receiver.
Designed for alerts
The planned alerting phase covers geofences and emergency transponder codes.

Built with

Java
Spring Boot
React
TypeScript
Supabase
Raspberry Pi

From radio signal to web UI
The Raspberry Pi decodes ADS-B signals and streams them to a Spring Boot service, which processes flight observations for the live dashboard and historical queries.
Flight-session processing
The service groups position updates into flight sessions and applies sampling and retention logic to manage stored data.
