How we deliver it →/
GovernmentNational observing infrastructure, delivered as one programme.
Programmes that build a country’s observing capability: national station networks, connectivity for remote sites, data platforms every ministry can read, and the qualification and training that keep it running long after commissioning.

Government, field by field.
National observing infrastructure is many networks under one programme: surface weather and river stations, upper-air soundings, the geodetic frame and national time, radiation monitoring and space weather. Each field below has its own rules, instruments, radio, power and crew work, from the first order to a network the country runs itself.
Specialized fieldNational weather and hydrology networks
Automatic weather stations, rain gauges and river gauges run as one national network, sited, calibrated and reported to WMO rules so every ministry and neighbour can use the data.The full field →Specialized fieldUpper-air soundings
Radiosonde stations that launch soundings on schedule, with ground receivers, gas handling and data checks run as part of the national observing programme.The full field →Specialized fieldGeodetic reference and national timing
Continuously operating GNSS reference stations and time references that hold a country’s coordinates and clocks to the global frames every map, survey and network depends on.The full field →Specialized fieldEnvironmental radiation monitoring
Gamma dose-rate stations across the country, reporting continuously to the national authority and its neighbours so that a release anywhere is seen at once.The full field →Specialized fieldSpace weather monitoring
Magnetometers and ionospheric receivers that measure geomagnetic storms and their effects on power grids, satellite navigation and radio, feeding national space weather services.The full field →04The problem
What this industry has to measure.
Emergency management, wildfire, flood and early-warning delivery. The demand signal is data gaps and sustained operation, not hardware.
01Gaps in national network coverage
02Data exchange across agencies

11Questions buyers ask
Before you scope it.
Who sells, and who owns the data?
Nexus Observatory Inc. is the seller of record. The data your systems collect stays yours, under the licence you choose.
Do we have to buy hardware?
No. We deliver as a managed service, a data licence or a system you own.
Can we start small?
Yes. Start with one station or one site, then grow to a fleet and a network on the same open protocol, without replacing what you bought.
Which standards do the systems meet?
Each system is drawn against the open protocol and the standards it is composed from, listed on this page.
Who issues warnings and official decisions?
Warnings, alerts and official acts stay with the competent authority. We supply the observing systems, the data and the evidence behind them.
What happens after go-live?
We run the systems to a written service level, with monitoring, repair and an evidence trail, or train your team to run them.
