Co-ATC Project Progress Log

Project Overview

AI-Enhanced Airspace Monitoring System - Think of it as the Tesla of air traffic control, but actually functional.

Phase 1: Foundation (COMPLETED ✅)

The boring but necessary stuff

Project Setup

  • ✅ Go Backend Architecture - Built with proper structure, none of that spaghetti code bullshit
  • ✅ SQLite Database - Because sometimes simple is better than complex
  • ✅ TOML Configuration - Easy config management, like changing TV channels
  • ✅ Structured Logging - So we know what the hell is going on

Core Data Pipeline

  • ✅ ADS-B Data Ingestion - Real-time aircraft tracking from multiple sources
  • ✅ Local & External API Support - Works with your home setup or external APIs
  • ✅ Aircraft Storage & Cleanup - Automatic data management, set it and forget it
  • ✅ RESTful API - Clean endpoints that actually work

Phase 2: Frontend Magic (COMPLETED ✅)

Making it look good

Web Interface

  • ✅ Interactive Map - OpenLayers with OpenStreetMap/CARTO basemaps, smooth as butter
  • ✅ Real-time Aircraft Visualization - See planes move in real-time
  • ✅ Aircraft Details Panel - All the info you need, none of the crap you don't
  • ✅ Historical Track Display - Where planes have been, where they're going

UI Improvements

  • ✅ Responsive Design - Works on phones, tablets, whatever
  • ✅ Search & Filter - Find aircraft fast, like Google but for planes
  • ✅ Status Indicators - Know when shit's working or broken
  • ✅ Phase Tracking - Flight phases from takeoff to landing

Phase 3: Audio Integration (COMPLETED ✅)

The fun stuff - listening to ATC chatter

LiveATC Streaming

  • ✅ Multi-Frequency Support - Monitor multiple radio frequencies
  • ✅ Audio Buffer Management - Smooth streaming without dropouts
  • ✅ Web Audio Streaming - Browser-friendly audio delivery
  • ✅ Concurrent Stream Handling - Multiple clients, one stream source

Audio Processing

  • ✅ FFmpeg Integration - Professional audio processing
  • ✅ Format Conversion - MP3 to PCM, whatever you need
  • ✅ Unified Audio Pipeline - One process, multiple outputs
  • ✅ Low-Latency Streaming - Real-time audio without delays

Phase 4: AI Transcription (COMPLETED ✅)

Where the magic happens

Real-Time Transcription

  • ✅ OpenAI Whisper Integration - Best-in-class speech recognition
  • ✅ Multi-Frequency Transcription - All channels transcribed simultaneously
  • ✅ WebSocket Broadcasting - Real-time transcription delivery
  • ✅ SQLite Storage - Permanent transcription records

Post-Processing Intelligence

  • ✅ GPT-4 Post-Processing - Clean up transcription errors
  • ✅ Speaker Identification - ATC vs Pilot classification
  • ✅ Callsign Extraction - Link transmissions to aircraft
  • ✅ Aviation Terminology - Proper ATC phraseology correction

Phase 5: ATC Chat Feature (COMPLETED ✅)

The crown jewel - AI ATC Assistant

OpenAI Realtime API

  • ✅ Voice Chat Integration - Talk to AI like a real controller
  • ✅ Real-Time Context Updates - AI knows current airspace situation
  • ✅ Session Management - Persistent chat sessions
  • ✅ Audio Streaming - Bidirectional voice communication

Intelligent Context

  • ✅ Live Airspace Data - Current aircraft positions and states
  • ✅ Weather Integration - METAR, TAF, NOTAM data
  • ✅ Runway Information - Active runways and configurations
