Cloud SaaS that predicts satellite conjunctions, optimises avoidance manoeuvres with AI, and runs an auction-based coordination protocol so operators agree which vehicle moves.
Space Guardian builds a cloud-based collision-avoidance platform for satellite operators. The system ingests orbital data, predicts conjunctions in real time, computes fuel-optimal manoeuvres, and uses a bidding mechanism so that only one of two operators performs the burn while the other compensates. Direct satellite commanding is planned; the goal is end-to-end automation that cuts staffing costs and extends satellite lifetime through 5–7 % fuel savings.
The idea won first place at the CASSINI Hackathon (November 2024) and the CASSINI Challenges Idea Track (June 2025). In March 2025 the company received €72 000 P2 pre-seed funding from the Slovene Enterprise Fund. It is preparing pilot projects with operators and is part of the CASSINI / EUSPA / ESA entrepreneurship ecosystem.
SPACE GUARDIAN d.o.o. was registered in Ljubljana on 7 February 2025 by co-founders Luka Zlatečan (CEO), Jernej Jan Kocica (CTO) and Janez Lapajne (Head of AI). Team size is currently 2–10.
