Project Overview
Our mission is to develop a sustainable solution for removing debris from geostationary orbit, ensuring the safety and longevity of vital space infrastructure.
Background & Motivation
Geostationary orbit is now clogged with defunct satellites and fragments, threatening vital communications and broadcast platforms. GEOOSC deploys a CubeSat constellation to safely capture and escort 990 kg of end-of-life debris into a dedicated graveyard orbit.
Objectives & Deliverables
- • Thrust-optimized propulsion for 250 kg per CubeSat
- • S-band comms with 15 min real-time telemetry uplinks
- • AI-powered object detection (≥ 90% accuracy)
- • Robotic arm for secure attachment
- • Autonomous navigation & obstacle avoidance
- • Flight-ready prototype demonstration
Design & Development
We used Quality Function Deployment (QFD) to align customer needs—size, cost, reliability—with technical specifications. The final design integrates propulsion, robotics, LiDAR, and on-board AI into a single compact CubeSat.
Final Design & Results
Our design achieves a 3 km/s rendezvous, matches the target velocity, and delivers > 100 N thrust per CubeSat. All performance metrics meet or exceed specification.
Prototype Verification
Lab tests show 95.4% detection accuracy (mAP@0.5) and 355 ms inference time; telemetry latency under 0.1 s—comfortably in the real-time regime.
Conclusions & Next Steps
GEOOSC paves a cost-effective path to GEO debris mitigation. Next: hardware miniaturization, extended mission duration, and constellation scaling.
