Is Cairn a mission assurance or certification system?
No. Cairn helps form and inspect the early model. It is not a certification authority or full mission assurance database.
AI-native systems engineering for CubeSat teams
CubeSat teams need disciplined systems thinking long before they need a heavyweight enterprise stack. Cairn helps turn a mission concept into a structured model with subsystems, requirements, interfaces, behaviors, verifications, and traceability.
Use Cairn to make mission, payload, bus, ground, and verification assumptions visible while the spacecraft design is still being formed.
The current workflow problem
Small satellite work crosses mission design, payload, avionics, communications, power, thermal, structures, ground operations, and verification. Student and early-stage teams often keep too much of that context in documents and meetings rather than a connected model.
What Cairn helps with
- Decompose mission, payload, spacecraft bus, and ground elements
- Capture requirements by subsystem and mission objective
- Define interfaces across power, data, thermal, structures, and operations
- Model operating modes such as safe, commissioning, nominal, and downlink
- Link verification intent back to requirements
Typical workflow
- Describe the mission concept and constraints
- Create the first system tree
- Add subsystem requirements and interfaces
- Model mission and fault behavior where assumptions matter
- Review verification coverage and trace links before formal review packages mature
What you get out
- Mission and spacecraft system tree
- Subsystem requirements
- Interface assumptions
- Operational states
- Verification records and trace links
FAQ
Can student CubeSat teams use Cairn?
Yes. Cairn is a good fit when a team needs a shared model before enterprise MBSE overhead is realistic.
Can Cairn represent subsystem interfaces?
Yes. Interfaces can connect model nodes and carry descriptions, protocols, and signals.
