Reference design, drawn to scale · drag to turn

  1. Cities · Open

    The city, measured block by block

    Street-level flood depth, air quality and heat, mobility and noise, carried on a municipal sensing and connectivity layer, with twins of the streets they sit in and open data residents can read. Needs: street flooding, air quality and urban heat, structural condition of public assets, connectivity for municipal sensors and open data for residents.

  2. Open · Connectivity

    Open with Connectivity

    Band tables and sources, Country guides and Coverage methods: free to use and build on. The enterprise layer adds private Wireless as a Service, AI-RAN deployment and Spectrum route support, delivered under contract by Nexus Observatory Inc. Open methods let anyone check how a product was made.

  3. Open · Sensors & instruments

    Open with Sensors & instruments

    Metadata and quality rules and Open networks on the grid: free to use and build on. The enterprise layer adds sensing as a Service, Calibration programmes and Qualification, delivered under contract by Nexus Observatory Inc. Open methods let anyone check how a product was made.

  4. Open · Data & licensing

    Open with Data & licensing

    Open tier and Dataset cards: free to use and build on. The enterprise layer adds paid tiers and Residency by contract, delivered under contract by Nexus Observatory Inc. Open methods let anyone check how a product was made. Service levels are written as numbers you can measure.

  5. Open · Earth observation & GeoAI

    Open with Earth observation & GeoAI

    Observatories atlas, World grid and Map sources with licences: free to use and build on. The enterprise layer adds capture campaigns and Site twins, delivered under contract by Nexus Observatory Inc. Open methods let anyone check how a product was made.

  6. Open · Field services

    Open with Field services

    Guides, Templates and Lifecycle: free to use and build on. The enterprise layer adds eight services and Government buyers, delivered under contract by Nexus Observatory Inc. Open methods let anyone check how a product was made. Every reading and every change leaves a record that can be checked later.

  7. Trust

    Every node proves what it is

    A node joins only after its hardware root of trust answers an attestation challenge. Keys stay in secure hardware, software arrives signed, and every reading carries a signature, so its origin can be checked by anyone downstream without asking us.

  8. Time and place

    Every reading carries when and where

    Readings are stamped against a disciplined clock, from satellite time or a PTP grandmaster, together with the station position and its siting record. When time or position is degraded, the record says so instead of hiding it, and every analyst downstream sees the same warning.

  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. Operations

    Every node watched, every incident closed

    The operations console shows every node with its state, its plan and its evidence. Alerts arrive with their data and a runbook; acknowledging one opens a work order, and an incident closes only when the cause is recorded and the fix verified.

  12. What you get

    Municipal sensing and connectivity layers

    City-wide LPWAN or private 5G as a shared layer for public sensors and services. Delivered as managed service, for cities, regional governments. Scale: City-wide. Service levels are written as numbers you can measure on your own dashboard. Changes are versioned, tested and reversible.

    Plan a cities deployment

    Tell us the sites, the measurements and the people who will use them. We reply with a design and a scope for cities. An engineer replies with a survey proposal and a scope, and the plan grows from one site to the network you need, at your pace.

01Open projects

What this community builds on.

Open hardware, software and data projects, named as references. Each keeps its own licence and its own governance.

  • Sensor.Community
  • OpenAQ
  • FloodNet
  • Smart Citizen Kit
  • Telraam
  • openSenseMap

02Open methods and templates

Every calculation, with a worked example.

Observatory templates for this industry, each a starting design you can read, run and adapt on the open protocol.

Template

Hybrid air-quality observatory

A few reference analysers and many low-cost nodes, with co-location calibration and an open-data feed.
Template

Street flood observatory

Ultrasonic depth sensors on poles report street-level water depth as open data and alerts.
Template

School connectivity observatory

A connected school as an observatory node: backhaul, Wi-Fi, a connectivity probe and an optional weather and air-quality station.
Template

Stadium operations private 5G slice

A private 5G slice for venue operations beside the neutral-host network, with crowd, heat and air sensing.

03Open data
