GNSS reference networks

Continuously operating stations, tied to the geodetic frame. The page on GNSS reference networks sets out the technologies it uses, the standards they follow and how we deliver it. 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.

The problem

Where and when, with the error bound

The products and services of Positioning, navigation and timing start with GNSS reference networks, time distribution, grandmasters and holdover and resilient PNT. 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.

Components

• Geodetic GNSS station on a deep-drilled braced monument (generic class, no brand)
• Robotic total station in a monitoring shelter
• Slope stability radar on a trailer
• Haul truck with onboard network and autonomy kit
• Private LTE mast on a solar skid
• “AI tower in a box”
• PTP grandmaster clock with GNSS antenna
• Data hall row pair with cold-aisle containment

   Grandmasters and holdover

   Reference clocks that keep time when the sky goes dark. The page on grandmasters and holdover sets out the technologies it uses, the standards they follow and how we deliver it. 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.

5. Area · Resilient PNT

   Resilient PNT

   Several sources, cross-checked, one trusted solution. The page on resilient PNT sets out the technologies it uses, the standards they follow and how we deliver it. 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.

6. Time and place

   When and where, on every record

   On a network for Positioning, navigation and timing, when and where are part of every record: a disciplined clock, from satellite time or a PTP grandmaster, and the station’s surveyed position. A degraded clock or position is written into the record for Positioning, navigation and timing, never hidden, and every user downstream sees the same flag.

7. Area · Time distribution

   Time distribution

   PTP, SyncE and NTP, engineered to the budget. The page on time distribution sets out the technologies it uses, the standards they follow and how we deliver it. 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.

8. Operations

   Every node watched, every incident closed

   Operators of a network for Positioning, navigation and timing see every node at once: its state, its plan and its evidence, in one console. Each alert for Positioning, navigation and timing arrives with its data and a runbook, and its incident stays open until the operator records the cause and verifies the fix.

9. Failure and recovery

   When a node fails, the fleet knows first

   When something fails on a network for Positioning, navigation and timing, the fleet knows first: the node buffers its data and fails over to a second link where one exists. The alert for Positioning, navigation and timing carries what a responder needs to act, and the record keeps every value once, with nothing lost.

10. Updates

    Updates in rings, with rollback

    No change reaches a whole fleet for Positioning, navigation and timing at once: software and configuration go to one canary site first, then to a few, then to all. Each ring for Positioning, navigation and timing passes only on health and data completeness, and a failed check returns every node to its last good release.

11. How it scales

    One base unit, repeated

    A network for Positioning, navigation and timing grows from one proven unit: a base node, its instruments, then the power and radio that make it a station. A relay turns stations into a site, a fleet repeats the site in many places, and capacity for Positioning, navigation and timing rises with each unit added, never by replacing what works.

12. What you get

    Open where it can be, contracted where it must be

    Anyone can use and build on the protocol, the methods and the open data behind Positioning, navigation and timing, free of charge. Under contract, Nexus Observatory Inc. builds and runs the sites, fleets and data tiers for Positioning, navigation and timing, priced per site and per fleet, with service levels written as numbers.

13. Next step

    Positioning, navigation and timing, planned with you

    Tell us which products and services of Positioning, navigation and timing you need, for which sites and by when. An engineer replies with a survey proposal, a design and a scope for Positioning, navigation and timing, and the plan grows from one site to the network you need.
