Mission Platform
Start closer
to orbit
Mission infrastructure is prepared ahead of need. Bring your payload or choose an established payload option.
01 · Ready before you arrive
Your mission starts further ahead
INTERFACE
One payload interface
Power, data, mechanical and thermal interfaces are standardised around a common payload specification.
BASELINES
Platforms prepared ahead of need
Each mass class has a fixed spacecraft baseline, developed independently of individual customer programmes.
STREAMLINED
The mission moves in parallel
Licensing, launch, ground and operations preparation can progress alongside payload integration.
Contract to orbit
Mission-specific assumptions apply.
02 · Quality by design
A known platform, every change verified
| Gate | What we check | What you receive |
|---|---|---|
| Interface definition | Mechanical, electrical, thermal, data and software interfaces, plus closure of mission-specific requirements | Payload ICD, interface documentation, compatibility report and open actions |
| Flatsat / HIL | Hardware-in-the-loop (HIL) testing of flight software, commands, telemetry, timing, payload data flow and fault handling on a flight-representative flatsat | Flatsat access, test procedures, interface support, logs and pass/fail evidence |
| Payload integration | Mechanical fit, electrical connection, flight configuration and end-to-end payload commanding, telemetry and data flow | Integration procedure, updated ICD, as-integrated configuration and functional test evidence |
| Environmental test | Vibration, thermal-vacuum and EMC of the integrated flight configuration against the agreed mission and launch requirements | Test plan, qualification or acceptance reports and closure of test actions |
| Mission rehearsal | Spacecraft, ground segment, nominal and contingency procedures, payload operations and data flow end to end | User manuals, operating procedures, rehearsal results and mission-readiness evidence |
| Launch integration | Launch interface, final flight configuration, launch-site checkout and readiness against provider requirements | Launch integration documentation, final configuration record and readiness evidence |
| LEOP & commissioning | Acquisition, deployment, communications, spacecraft health, attitude performance and payload activation in orbit | LEOP and commissioning report, on-orbit verification results and the agreed operational baseline |

BUILD
Platform and payload integration
We provide the spacecraft, integrate the payload and deliver the flight configuration.
PLATFORM · PAYLOAD INTEGRATION · FLIGHT SOFTWARE
LICENSING
Mission and spectrum licensing
We coordinate the regulatory work required to take the mission to flight.
MISSION LICENSING · SPECTRUM · DOCUMENTATION
LAUNCH
Launch procurement and integration
We manage the launch slot, interfaces, logistics and launch-site integration.
PROCUREMENT · MANIFEST · LOGISTICS · LAUNCH INTEGRATION
GROUND
Ground and mission control
We provide the ground connectivity, mission control and data path needed to operate the spacecraft.
GROUND NETWORK · MISSION CONTROL · SECURE COMMS
OPERATIONS
LEOP through routine operation
Ready to operate from day one, the spacecraft can be run by Exobotics through LEOP, commissioning and routine bus operations, or under a customer-led operations model.
