System designer and integrator, site to grid.

We build the grid that observes the planet.

Nexus Observatory Inc. designs, builds and runs observing sites and the grid that joins them, for public agencies, utilities, cities, ports, mines and farms. Instruments, power, radio, edge compute, timing and trust arrive as one accountable system, built on the open Observatory Protocol.

  1. The problem

    Risks nobody is watching

    Rivers rise, slopes creep and lines sag where no instrument reports in time. Where instruments do exist, each speaks its own format on its own clock and under its own terms, and nobody can prove when a reading was taken. Decisions that cost lives and money wait for data that is late, partial or impossible to check.

  2. What we do

    One accountable system on every site

    Nexus Observatory Inc. designs and builds observing sites and the grid that joins them. Instruments, power, radio, edge compute, timing and trust arrive as one system on the open Observatory Protocol, and one design repeats from the first site to the last. Watch a station come up: power, node, link, then its first signed reading.

  3. How it works

    From instrument to evidence, in one chain

    A road weather station measures the pavement and the air. The node beside it timestamps, signs and buffers each reading; a small-cell pole carries it to the edge, where it is checked and fused; the core keeps it as a record with its metadata, calibration and provenance. If a link drops, the node holds the data until the link returns.

  4. Mining

    Tailings that report before they move

    On a tailings dam, piezometers and inclinometer strings read pore pressure and movement in the embankment, a slope radar scans the pit wall and a private LTE mast carries everything to an edge node on site. When pressure trends toward its threshold, the operations console raises the alert with the reading, its time and its source attached.

  5. Energy

    A grid edge that keeps time and proves it

    Along a distribution feeder, line sensors and pole-top transformers report load, sag and faults. A grandmaster clock disciplines every node to one shared time over PTP, so a fault is located from when each sensor saw it, and a hardware security module signs what each node reports. Operators act on readings they can verify, not on readings they have to trust.

  6. Cities

    Air quality, street by street

    Small-cell poles on a city’s junctions carry air-quality nodes as well as radio. Each node reports particulates and gases with its calibration attached; the edge corrects them against reference stations and publishes open maps and alerts for schools, clinics and transport, with the licence and the method on every product. The poles that sense also carry the network.

    CitiesSee the data products
  7. Ports and coasts

    The port that sees the approach

    A compact radar on the breakwater scans the approach while a weather station reads wind and visibility at the quay. Their data meet at edge compute in the terminal, are timed and fused there, and reach the harbour office as one picture of sea state and traffic, with every value traceable to the instrument that measured it.

  8. Wildfire

    Smoke seen sooner, crews sent faster

    Cameras on the ridges watch the forest while a weather station reads wind and humidity. When smoke rises, two bearings fix its position; the edge confirms the detection and the operations console dispatches a drone and a crew with the location, the images and the weather attached. Every alert leaves in an open format the agencies already use.

  9. Scale

    From one base unit to the planet

    Every site is the same base unit, repeated: a station, a site, a fleet, then a network federated across regions. Satellites and their ground stations join on the same terms as a mast in a valley. Capacity grows by adding units, not by redesigning, and every node, wherever it stands, joins, proves itself and publishes through one open protocol.

  10. How we work

    Order, survey, install, operate

    You bring the site and the question. We survey the ground, the spectrum and the power, design the stations to the place, install and commission them against the plan, then operate them: monitoring, updates in signed stages, calibration and repair by one accountable crew. Plan it with us, configure a station, or model the site yourself first.

IHeritage

From naked eye to planetary grid.

Every era of observation solved what the one before could not, and the record names the observatories and the people behind each step: a better instrument, a shared clock, a wire, an orbit, a network. The open problem now is coordination. That is the one we work on.

Each frontier technology is traced to the release, study or framework it comes from: 3GPP non-terrestrial networks, O-RAN, IMT-2030, analysis-ready data, geospatial foundation models. They arrive on the same site at the same time. The site has to absorb all of them.

IIIProtocol

One protocol for instruments that have never met.

The protocol takes a node from unboxed to trusted through its functions: join, admit, describe, time, observe, qualify, federate, orchestrate, correct, exchange, prove, exit and decommission. Every value carries its metadata, clock, quality and provenance. No vendor, cloud or central service becomes the owner of local truth.Open the specification

01JoinA node proves what it is, receives an identity and a policy, then a signed plan.

02AdmitProviders enter by manifest, rights, security and technical review, for a stated scope.

03DescribeEvery instrument and observation carries what, where, how and by whom.

04TimeOne time base across the grid, with time quality as explicit state.

05ObserveStreams and files move over whatever link the site has, with store and forward.

06QualifyQuality flags, calibration and provenance travel with each value.

07FederateNodes form cells, cells form clusters, and clusters federate across trust domains.

08OrchestrateSoftware, configuration and upgrades roll out by signed plan, with evidence for every change.

09CorrectAn upstream correction marks dependants stale, triggers recompute and publishes a new version.

10ExchangeGoverned products reach people and applications through versioned APIs, events, maps and exports.

11ProvePeers answer unpredictable challenges and emit signed proof receipts for an independent verifier.

12Exit and decommissionEvery material provider has an open export and replacement path, and decommissioning closes the record.

Open protocol, open process

Open specification, open change process, open to any implementer. Nexus Observatory Inc. implements the protocol and builds enterprise systems on it.
