Reference design, drawn to scale · drag to turn

  1. Oceans · Systems and technologies

    From the coastline to the open ocean

    Wave buoys and tide gauges, profiling floats and coastal water quality, ports and shipping lanes, and satellite links where no cable runs, with every observation carrying its position, time and quality flag. Needs: waves, tides and sea level, water temperature and salinity, coastal water quality, port and vessel conditions and connectivity at sea.

  2. Platform · Sensors & instruments

    Measurements that carry their own proof

    Weather and environment stations to WMO practice, RF spectrum sensing in the band, and calibration that is traceable, recorded and repeated. Every value leaves with its metadata, quality flag and provenance. Or buy the observations and leave the hardware to us: Sensing as a Service.

    Sensors & instruments
  3. Platform · Connectivity

    Private 5G, AI-RAN and orbit, on site

    Standalone private 5G and O-RAN, AI-RAN on shared accelerated compute, LEO and GEO backhaul and 3GPP direct-to-device, LPWAN and mesh for sensors over kilometres, PTP timing inside the budget, and the spectrum route for each country. Every reading and every change leaves a record that can be checked later.

    Connectivity
  4. Platform · Data & licensing

    Grid data, licensed for your use

    Research, commercial API, enterprise and government tiers, the licence of every source carried through to every product, routes from licensed to open release, and residency fixed by contract. It is delivered and supported by Nexus Observatory Inc. The evidence travels with the data wherever it goes.

    Data & licensing
  5. Platform · Space and satellite systems

    From orbit to the ground, on one protocol

    Spacecraft buses and payload classes, constellations sized to revisit and coverage, non-terrestrial networks and 3GPP direct-to-device, tasking and downlink, and space safety from tracking to conjunction awareness. Every pass, product and link carries its provenance into the grid. The same design repeats from the first site to the last.

    Space and satellite systems
  6. Platform · Earth observation & GeoAI

    The ground, measured and modelled

    Ground-segment downlink and processing at the edge, drone and imagery campaigns planned to the ground sample distance, site twins measured in 3D, and GeoAI trained and checked against field truth, with the source and licence of every layer in view.

    Earth observation & GeoAI
  7. Platform · Edge compute & AI

    Inference beside the instrument

    A modular edge data centre at the foot of the tower, multi-access edge computing one hop from the radio, inference on the live stream, scientific models run where the data lands, and physical AI for drones and robots, inside published red lines.

    Edge compute & AI
  8. Platform · Positioning, navigation and timing

    Where and when, with the error bound

    GNSS reference stations tied to the geodetic frame, PTP and SyncE time distribution engineered to the budget, grandmasters and holdover that ride through outages, and resilient PNT that finds jamming and spoofing before a timestamp goes wrong. It runs on the open Observatory Protocol, so other providers can join.

  9. How it scales

    One base unit, repeated

    A programme starts with one base node and the instruments it reads. A station adds power and radio, a site adds a relay, a fleet repeats the proven site across many places, and a network federates fleets through edge and core. Capacity grows by adding units, never by replacing what works.

  10. Updates

    Updates in rings, with rollback

    Software and configuration reach the fleet in rings: a canary site first, then a few, then all, each ring gated on health and data completeness. A failed gate stops the wave and returns each node to its last good release, without a site visit.

  11. Field service

    One crew, from survey to repair

    The same crew surveys, installs, commissions, calibrates and repairs, working from the site’s own record. Each visit updates it, so the next crew knows exactly what is there, when it was last checked and why it was changed. Spares and references are planned from that history.

  12. What you get

    Ocean and coastal observing

    Moored buoys, profiling floats, tide and wave gauges, coastal radar and AIS reception with quality-controlled feeds. Delivered as managed service and data licence, for ports, coastal agencies, offshore energy, fisheries. Scale: Coastline to basin. Service levels are written as numbers you can measure on your own dashboard.
