Public safety · Open
Warning time, gained at the sensor
Observing networks, communications and data for emergency management: hydromet and fire-weather stations, camera towers with inference at the edge, deployable cells for incident command, and the integration that hands a trigger to the alerting authority, which keeps every decision. Needs: rainfall, river level and soil moisture, fire weather, smoke and ignition, ground movement and seismic activity, communications at the incident base and reporting uptime and data latency.
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.
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.
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.
Open · Edge compute & AI
Open with Edge compute & AI
Class assumptions and Power and thermal methods: free to use and build on. The enterprise layer adds MEC deployment and Edge AI sites, delivered under contract by Nexus Observatory Inc. Open methods let anyone check how a product was made.
Open · Hardware & power
Open with Hardware & power
Device classes with 3D models and Reference designs (licence pending): free to use and build on. The enterprise layer adds kit supply, Bills of materials and deployment plans and OEM co-engineering, delivered under contract by Nexus Observatory Inc. Open methods let anyone check how a product was made.
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.
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.
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.
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.
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.
What you get
Hydrometeorological and flood observing networks
Stream gauges, rain gauges, weather radar and automatic weather stations built to WMO practice, reporting through WIS 2.0 where the agency requires it. Delivered as hardware + software, managed service and build-operate-transfer, for national meteorological and hydrological services, river-basin agencies, utilities.

Tell us the sites, the measurements and the people who will use them. We reply with a design and a scope for public safety. 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.
