Engineering the pathway from evidence to space.
IOSTS is IYABOKO’s simulation-first, evidence-gated research and engineering programme for developing, testing and progressively reviewing orbital research-spacecraft architectures.
One programme with a clear engineering and evidence boundary.
IOSTS provides a governed research structure for moving a space-system concept from stated assumptions into traceable requirements, controlled models, repeatable simulation, verification evidence, findings, remediation and accountable review.
Two tracks. One non-negotiable evidence boundary.
Demonstrated engineering and speculative hypotheses are deliberately separated so exploratory research cannot be mistaken for validated spacecraft capability.
IOSTS-R
Develops orbital research-spacecraft architectures through conventional engineering models, explicit assumptions and progressively stronger evidence.
IOSTS-X
Provides a controlled environment for modelling, questioning and visualising speculative future-physics and intergalactic research concepts.
Make every name and responsibility unambiguous.
The hierarchy below separates the domain solution, research programme, engineering track, demonstrator project, mission scenario, assurance infrastructure and public interface.

|---|---|---|---|
| Space OS | IYABOKO domain solution for space-system readiness, evidence preparation, simulation planning and assurance. | Public solution pathway | Preparation and assurance support only |
| IOSTS Programme | Research and engineering programme for orbital and future space-system concepts. | Research programme established | No flight or regulatory authority |
| IOSTS-R | Evidence-grounded engineering research track using demonstrated or conventionally modelled technology. | R1 Integrated Simulation active | Human-gated progression |
| IOSTS-X | Exploratory future-physics research track for falsifiable hypothesis development. | Research HOLD | No engineering promotion without evidence |
| IOSTS-R-D01 | First IOSTS-R development and public engineering demonstrator project. | Simulation / development | Internal research designation |
| IOSTS-R-MISSION-R0 | Small uncrewed orbital research-demonstrator mission scenario. | Simulated mission | Flight authority NONE |
| SpaceCore | Evidence-centred infrastructure connecting requirements, models, telemetry, evidence, verification, findings and Sentinel gates. | Public demonstrator active | AI authority NONE |
| Live Mission | Interactive browser interface for disturbing the simulated mission and observing assurance-state changes. | Simulated telemetry | No external command endpoint |
IOSTS-R-D01 turns the research architecture into an inspectable engineering chain.
The demonstrator does not imitate a finished mission-control product. It exposes how configuration changes, anomalies and insufficient evidence affect verification and human-gate status.
IOSTS-R-MISSION-R0
A small uncrewed low-Earth-orbit research-spacecraft scenario coupling Power → Thermal → Avionics → Communications → Telemetry → FDIR within a controlled simulation and evidence environment.
Progress is evidence-gated—not presentation-gated.
Each transition requires new evidence appropriate to the proposed system state. Later stages are conditional research targets, not promises of qualification or flight.
Baseline
Mission definition, system boundary, requirements, assumptions and configuration baseline.
EstablishedIntegrated Simulation
Coupled Power, Thermal, Avionics, Communications, Telemetry and FDIR evidence demonstration.
Current stageBench Evidence
Controlled low-energy breadboard measurements only when scope, safety and physical work are authorised.
Future · conditionalSIL / MIL / HIL
Software-, model- and hardware-in-the-loop evidence with model truth, sensor, software and physical state kept distinct.
Future · conditionalEngineering Model
Developmental engineering model only after earlier evidence supports physical integration and controlled testing.
Future · conditionalExternal Review
Independent examination of configuration, requirements, evidence, verification, findings, safety assumptions and residual uncertainty.
Future · conditionalFlight Candidate
Conditional future designation only if required evidence, qualified review, certification and external authorities are satisfied.
Not claimedDo not ask only whether the spacecraft is ready. Ask to see the evidence chain.
SpaceCore and Sentinel make the basis, configuration, limitations and unresolved decisions behind a readiness statement visible.
Evidence-centred engineering record
The programme distinguishes a model result from an observation, an observation from qualified evidence, and evidence from authority to act.
A practical programme structure for deeper technical work.
Each workstream should produce explicit assumptions, requirements, datasets, models, tests, evidence packages, findings and review decisions.
Mission & Systems Architecture
Mission objectives, operating context, stakeholders, boundaries, payload role, subsystem interfaces and configuration structure.
Power, Thermal & Avionics
Coupled state models, load cases, thermal limits, command/data handling, failure propagation and safe-state assumptions.
Communications & Telemetry
Telemetry requirements, data provenance, timing, staleness, communications-loss scenarios and ground–space interface concepts.
Digital Twin & Simulation
Model truth, observed state, residuals, uncertainty, simulation validity, scenario control and later SIL/MIL/HIL preparation.
Verification & Assurance
Requirements mapping, test methods, evidence quality, critical controls, anomaly findings, remediation and reassessment.
Orbital Responsibility
Mission-lifetime assumptions, communications dependencies, debris considerations, end-of-life planning and qualified external handoff.
Disturb the simulated mission. Watch the evidence and assurance state respond.
SpaceCore is the public demonstration and evidence infrastructure connecting the IOSTS-R research track, simulated telemetry, digital-twin state, configuration context, verification evidence, Sentinel conditions and accountable human decision gates.
It shows what has been demonstrated, what changed, what remains uncertain and which human decision must happen next.
Developmental simulation is not operational spacecraft capability.
IOSTS public interfaces are research, simulation and evidence-readiness demonstrations. Capability statements must remain tied to the evidence actually available at the current programme gate.
Build the next evidence gate through clear roles and scoped work.
IOSTS welcomes appropriately bounded collaboration where objectives, data, intellectual property, attribution, review responsibility, funding and authority are agreed before substantive work begins.
Independent research and validation
Research-question development, model review, simulation methods, verification design, reproducibility and independent evidence assessment.
