NovaGen - Real-Time Orbital Collision Risk Prediction System

A cutting-edge space situational awareness platform that tracks thousands of satellites and predicts collision risks using advanced machine learning.

Overview

NovaGen is a comprehensive orbital collision risk prediction system that provides real-time monitoring of space objects, advanced machine learning-based debris detection, and immersive 3D visualizations. The system processes live satellite data from Celestrak and uses an ensemble of machine learning models to identify potential collision risks.

Key Features

Real-Time Space Object Tracking

• Live Data Feed: Processes over 12,000+ space objects in real-time
• TLE Integration: Fetches latest Two-Line Element data from Celestrak
• Automated Updates: Background data refresh every 5 minutes

Advanced Machine Learning

• Ensemble ML Models: 4-model ensemble (Random Forest, XGBoost, LightGBM, CatBoost)
• Neural Networks: LSTM/GRU architectures for trajectory prediction
• High Accuracy: Advanced feature extraction from orbital elements
• Real-Time Predictions: Continuous risk assessment and alerting

Immersive 3D Visualizations

Main 3D Visualization
