Architecture
How test and qualification is built.

One reference architecture under every deployment: the layers of a site, the protocol functions this platform relies on, and the evidence that travels with every observation.

Frontier and research

In Test and qualification, the frontier and research layer holds quantum magnetometers and gravimeters, distributed fibre-optic sensing and machine-learning calibration of sensor networks, each drawn against the standard it follows. Atomic sensors with higher sensitivity and less drift for geophysics and navigation backup.

সমস্যা

Tested against the specification. State on record

This page shows how Test and qualification is put together, layer by layer, from the instrument to the record. Lab and field testing of devices and releases, conformance runs against the protocol, interoperability events where suppliers meet on one test plan, and evidence bundles a buyer, an auditor or a regulator can check without taking our word for it.

Components

  • Pole-mounted edge gateway node
  • Automatic weather station (AWS) to WMO siting practice
  • Particulate monitoring station and sensor node
  • Compact X-band weather radar / ISAC sensing node on a lattice tower top
  • Street small-cell pole with an air-quality node
  • “AI tower in a box”
  • Hardware security module, 1U, in an edge rack
  • Data hall row pair with cold-aisle containment

    Tested against the specification. State on record

    This page shows how Test and qualification is put together, layer by layer, from the instrument to the record. Lab and field testing of devices and releases, conformance runs against the protocol, interoperability events where suppliers meet on one test plan, and evidence bundles a buyer, an auditor or a regulator can check without taking our word for it.

  8. আস্থা

    Proved before it is trusted

    A network for Test and qualification admits a node only once its hardware root of trust has answered an attestation challenge, whoever supplied it. Signed software, keys kept in secure hardware and a signature on every record let anyone check where a value for Test and qualification came from.

Conductivity, temperature and depth instruments for salinity and density profiles. Moored and hull-mounted profilers for currents through the water column.

  12. What you get

    Open where it can be, contracted where it must be

    What is open for Test and qualification is free: the protocol, the methods and the open data can be used and built on by anyone. What must be contracted for Test and qualification, sites, fleets, managed operations and data tiers, Nexus Observatory Inc. delivers at a price per site and per fleet, with service levels in numbers.

  13. Next step

    Test and qualification, planned with you

    Tell us which layers of Test and qualification you already run and which you want us to design and deliver. An engineer replies with a survey proposal, a design and a scope for Test and qualification, and the plan grows from one site to the network you need.

01Reference architecture

From one instrument to the grid.

Every deployment is drawn on the same six layers. A typed contract sits at every boundary, so parts from different makers fit together.

  1. 01InstrumentThe sensor or radio that makes the measurement, with its calibration.
  2. 02NodeThe device that hosts instruments: identity, time, power and storage.
  3. 03SiteNodes in one place, on one mast or in one shelter, with their links.
  4. 04CellSites that share a backhaul, a power plan and an operator.
  5. 05ClusterCells run as one service, with one fleet plan and one evidence trail.
  6. 06GridClusters that federate across owners through the open protocol.
