USE CASES

Every system class.One lifecycle.

The same eleven-stage lifecycle, the same review gates and the same ELANG model run whatever the system is. Two of these are live in the platform — the seeded Marlin-XR demo ledger, forty items across all eleven stages, and the Kestrel-1 worked example — and three are the audited ELANG reference models shipped in the repo. Each card says which it is.

MRLN-XRSubsea autonomy

Marlin-XR Seabed Survey AUV

Surface / subsea vehicle — ISO 3691-4, COLREGs / IMO MASS Code

An autonomous underwater vehicle surveying the export-cable corridor of the Dogger Bank offshore wind farm. The bundled demo ledger: forty items seeded across all eleven lifecycle stages, from the mission brief to the deployment procedure.

KSTL-1Uncrewed aircraft

Kestrel-1 Survey UAV

UAV — NASA SE Handbook Rev.2, EASA UAS 2019/947

A fixed-wing survey UAV, seeded as a worked example: eight requirements, six components, four suppliers and four verifications, wired into a traceability graph, with a real ELANG system_model and an inline Technical Data Package.

KRNSIndustrial robotics

Kronos Robotic Work Cell

Production machine / manipulator — ISO 10218, ISO 13849, ISO 230

A six-axis robotic work cell modelled end to end in ELANG as an audited reference — roughly a thousand lines carrying a functional-safety design to ISO 13849-1 Performance Level d, with every safeguard traced to the hazard it mitigates.

SG80Grid-scale energy

SunnyGrid80 Solar-Storage Plant

Generic system (ISO/IEC/IEEE 15288) with electronics and cyber assurance

An 80 MW photovoltaic plant with a 40 MW / 80 MWh battery energy-storage system and its grid substation, modelled in ELANG as an audited reference to UL 9540A and IEC 62443 — a system-of-systems where the interfaces carry as much of the design as the boxes.

RDRRF & radar sensing

Embedded Radar Sensing Module

Embedded RF / radar — ITU Radio Regulations, IEC 61000 / 60068, IPC-2228 / 6018

An embedded radar sensing module — the system class the RF/radar recipe covers: a mixed-signal board where spectrum, EMC, environmental and fabrication standards constrain the design as hard as the sensing requirement does.

Yours is the sixth.

Tell us what the system is and the one requirement that keeps you up at night. We will take it through the ledger and walk a gate with you.
