NSU AI SAT
Active
Overview
The increasing congestion of Earth’s orbital environment poses significant challenges to both existing satellite systems and future space missions. The prevalence of Space Resident Objects (SROs), which include cooperative and noncooperative satellites as well as space debris from previous missions, necessitates a comprehensive and technologically advanced handling approach. For future on-orbit servicing, rendezvous and debris removal missions, onboard detection and tracking of spacecraft is an essential requirement.
NSU AI SAT is a 3U cubesat built for this purpose. The cubesat operates in a LEO orbit and detects and tracks neighbouring Space Resident Objects (SRO).
System Architecture
The cubesat integrates multiple subsystems for autonomous operation in space:
- Camera: Primary imaging sensor for SRO detection and visual tracking
- ADCS (Attitude Determination and Control System): Stabilizes and orients the satellite for precise pointing
- Leopard: Onboard computing platform for AI/ML inference
- OBC (Onboard Computer): Central command and data handling unit
- SDR (Software Defined Radio): Communication subsystem for telemetry and command
- EPS (Electrical Power System): Power generation and distribution
- Battery: Energy storage for eclipse periods
- Solar panel: Primary power generation
- Antenna: RF communication link with ground stations
