Current pre-flight mission
Sovereign GEO
Custody.
A proposed mission to help a sovereign customer assess whether custody of a designated geostationary asset is intact, degraded or lost.
The customer question
Custody assessment for a designated GEO asset.
A useful answer needs more than an image. It needs a calibrated observation, an orbit estimate, a clear account of uncertainty and a result another authorised party can check.
Object and decision window
Agree the target, authority, priority, operating constraints and success test.
Calibrated observations
Record timing, sensor state, calibration and the source frame for each observation.
Orbit estimate and uncertainty
Associate observations, fit the orbit and make ambiguity visible rather than hiding it.
Signed custody record
Package observations, orbit products, alerts, source hashes and processing history.
Current architecture
Current pre-flight architecture.
The design places a Sirona GEO custody payload and ground product on a dedicated partner spacecraft. Mission-specific tasking, processing, customer workflow and evidence logic remain with Sirona while the flight-proven bus and specialist services are procured.
Sirona must control
- Mission and payload requirements
- Tasking and customer workflow
- Detection, tracking and orbit logic
- Calibration knowledge and evidence format
- Operational authority, keys and data rights defined in contract
Initially procured
- Flight-proven spacecraft bus
- Conventional avionics and power hardware
- Launch and ground-station services
- Environmental test facilities
- Insurance and specialist integration
Evidence boundary
Evidence available today.
Mission software and internal analysis are available for review. Real-sky validation, representative hardware and flight evidence remain outstanding.
Task packaging, synthetic observations, detection, tracklets, orbit estimation, alerts, signed evidence bundle and replay.
Analytical trades, synthetic injection tests, controlled physics checks and programme baselines.
Customer acceptance, a multi-night real-sky campaign and independent reproduction of the result.
Representative hardware, supplier selection, regulation, environmental test and system qualification.
Commercial entry
GEO custody feasibility study.
The study produces a decision definition, observing concept, acceptance scenario, control-rights schedule, risk register and costed route to a mission.
