Two operators rehearsing continuity and failover in a representative hardened mission node
Controlled Sirona concept. Representative continuity and failover rehearsal for a future sovereign mission node; no operational system, customer, live spacecraft contact, facility or service is claimed.

Sovereign mission system

Sovereign authority across
spacecraft, ground and data.

A dedicated sovereign system is defined by customer authority over tasking, command, keys, data, acceptance and continuity.

Customer rights

Operating rights that define a sovereign system.

Each right must be explicit across the spacecraft, ground, software, supplier and service agreements.

Tasking authority
Who may request, prioritise and cancel a mission action.
Command authority
Who may approve changes that affect the asset or service.
Key authority
Who controls cryptographic identity, access and recovery.
Data authority
Where raw observations, derived products and logs may reside.
Release authority
Who may accept and distribute the resulting intelligence product.
Step-in authority
What happens if a supplier, operator or service fails.

Delivery options

Delivery models matched to customer authority.

The correct model depends on customer authority, urgency, mission sensitivity, capital and the evidence available.

Reserved mission capacity

Defined priority and operating rights on a validated Sirona mission service.

Future, requires capacity

Dedicated customer node

A customer-specific spacecraft and ground configuration with agreed ownership and control.

Future, gate dependent

Sovereign mission system

Orbital capacity, local ground, mission operations, training and lifecycle support.

Future, programme delivery model

Current boundary

Current programme boundary.

No Sirona sovereign system is operational today. Sirona can study the control model now. Capacity, facilities, licences, suppliers and service commitments require later evidence and agreement.

Can begin now

Mission definition, authority map, data and key requirements, acceptance design and supplier terms.

Requires a programme

Ground environment, identity, key custody, staffing, training, operational readiness and continuity.

Requires an asset

Capacity priority, mission control, telemetry history, calibration access and asset economics.

Requires approval

Regulation, spectrum, remote sensing, export, security, insurance, launch and responsible operations.
