Optical transceiver & telescope
Transmit and collect the optical signal. Aperture, optical power and receiver design are selected through the link budget.
Satellite interlink terminal
Connect spacecraft across a constellation.
A satellite interlink connects one spacecraft to another before traffic reaches a ground gateway. In the Star Jumper architecture, this is the orbital transport building block: mission requirements determine the paths, terminal configuration and handover strategy.

Satellite interlink terminal
Connect spacecraft across a constellation.
Discuss this connection ↗Inside the device
Core components and their roles.
The final configuration is selected around the customer requirement and engineering evidence.
Pointing, acquisition & tracking
Locate the counterpart terminal and maintain alignment as the spacecraft move.
Modem & spacecraft interface
Connect the optical channel to onboard data handling, coding and the spacecraft network.
Network & mission control
Coordinate contact schedules, routing, terminal health and authorised operational changes.
Your requirements
What we scope with your team.
Your existing architecture, operating conditions and growth priorities guide the solution.
- Orbit geometry, expected separation and contact opportunities
- Traffic demand, latency priorities and onboard routing
- Mass, volume, power, thermal and spacecraft interface limits
- Mission lifetime, redundancy and ground operations responsibilities
Pilot & acceptance
Prove the part that matters to your service.
Model the contact geometry and link budget, then test representative terminal and network interfaces in a controlled environment. Hardware and flight qualification require their own agreed programme.
- Acquisition and reacquisition against a defined scenario
- Measured data delivery and error behaviour under the agreed link conditions
- Routing, contact handover and recovery from an unavailable path
- Traceable test results and an agreed list of remaining mission dependencies
Designed to scale
Expand with a documented operating model.
Evaluate how additional spacecraft change contact scheduling, route choice, gateway loading and operational oversight. Expansion is gated by traffic modelling, redundancy and evidence from the pilot.
