Satellite Constellation Operations
The ground software for operating a satellite constellation: mission planning, flight dynamics, contact scheduling, command and control, and payload delivery.

What this diagram shows
- Mission planning turns customer requests into satellite tasks
- Flight dynamics predicts orbits and plans manoeuvres
- Contact scheduling shares ground stations across the fleet
Prompt used
Constellation operations architecture: customers submit imaging or data requests through a customer portal, the mission planning system turns them into satellite tasks, flight dynamics computes orbits, passes and collision avoidance manoeuvres, the contact scheduler books ground station passes across the network, command and control uplinks plans and monitors satellite health, and the payload data pipeline processes downlinked data and delivers it to customers.
