RF preparation
Anechoic-chamber setup.
Personnel are present, so the scene represents alignment and instrumentation preparation with RF transmission off. It does not claim a completed EMC campaign or result.
Technology
A controlled mission chain
from tasking to evidence.
Sirona connects payload, command, processing and signed evidence while identifying which elements are implemented, proposed or awaiting external validation.
Architecture
Mission architecture and authority.
Every interface has an owner, an acceptance condition and a record. The architecture is designed to preserve customer control without pretending that all flight hardware already exists.
Customer authority
Mission request
Identity, role, decision, limits and approval policy.
Mission operations
Mission planning and command
Tasking, scheduling, command approval and safe-state logic.
Space segment
Calibrated observation
Payload, time, calibration, attitude and platform state.
Evidence system
Orbit estimate and signed record
Processing, uncertainty, provenance, alert and replay.
Payload and platform
Mission-specific payload, built on proven spacecraft infrastructure.
Sirona intends to retain payload requirements, system architecture, timing, calibration, tasking, evidence and mission authority. Proven buses, conventional subsystems, launch and environmental services can be procured from qualified suppliers.
- Current baseline
- GEO custody payload and ground product on a dedicated partner spacecraft.
- Proposed direction
- A staged route to spacecraft and mission capacity Sirona owns or controls.
- Evidence boundary
- No selected bus, contracted payload, flight unit or operational satellite.
Verification environments
Different questions need different test environments.
Sirona intends to move from controlled setup and real-sky observation to representative hardware and environmental evidence. The scenes below describe future validation routes, not completed Sirona tests.
Real-sky route
Observe before committing to flight.
A future provider observatory could support multi-night GEO observations, reference comparison and independent replay. No telescope access or measured result is claimed.
Technology foundation
Three working foundations.
Ground evidence, secure mission operations and flight software interfaces are implemented in the workspace. They remain pre-production, unqualified and not customer accepted.
Signed evidence pipeline
Tasking, synthetic observation, detection, tracklets, orbit estimate, uncertainty, alerts, evidence bundle and replay.
Implemented and internally testedSecure mission operations
Command policy, cryptography, communications, audit, API, SDK, operations console and deployment assets.
Pre-production workspaceFlight software interfaces
Scheduling, fault handling, secure-element interfaces, attestation and reconfiguration patterns on host and emulated targets.
Not flight qualifiedMaturity
Current technology maturity.
Passing local tests matters. It does not replace customer acceptance, independent validation, target hardware or flight qualification.
