Free tool launched to forecast satellite collision risks for CubeSats and smallsat missions

NEW YORK - April 10, 2025 - PRLog -- A new web-based platform, Guardi.space, has launched to help small satellite operators and CubeSat teams track potential orbital collisions. The tool uses public Two-Line Element (TLE) data and the SGP4 model to forecast conjunctions up to 14 days ahead.  Guardi.space is free to use, does not require login or subscription, and is designed with small teams in mind. It offers a clean web interface for scanning possible close approaches, assigning risk levels (high/medium), and tracking specific satellites. Alerts and a live dashboard are included.  "Many smallsat missions don't have access to full-scale conjunction analysis tools," says the developer of the platform. "Guardi.space aims to fill that gap with a lightweight solution that focuses on accessibility and clarity."  The platform updates every 6 hours and includes basic covariance-based filtering using a simplified Chan/Alfano method to improve risk classification.  Guardi.space is already live and accessible at https://guardi.space.
