GNSS positioning and augmentation

In Positioning, navigation and timing, the GNSS positioning and augmentation layer holds multi-constellation, multi-frequency receivers, RTK networks and NTRIP and PPP and PPP-RTK, each drawn against the standard it follows. Receivers using GPS, Galileo, GLONASS, BeiDou and regional systems on several frequencies for accuracy and robustness.

问题所在

Where and when, with the error bound

This page shows how Positioning, navigation and timing is put together, layer by layer, from the instrument to the record. 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

   Where and when, with the error bound

   This page shows how Positioning, navigation and timing is put together, layer by layer, from the instrument to the record. 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.

   GNSS positioning and augmentation

   In Positioning, navigation and timing, the GNSS positioning and augmentation layer holds multi-constellation, multi-frequency receivers, RTK networks and NTRIP and PPP and PPP-RTK, each drawn against the standard it follows. Receivers using GPS, Galileo, GLONASS, BeiDou and regional systems on several frequencies for accuracy and robustness.

3. Architecture · Spectrum, timing and PNT

   Spectrum regimes and access

   In Positioning, navigation and timing, the spectrum regimes and access layer holds exclusive licensed spectrum, tiered shared access and local and light licensing, each drawn against the standard it follows. Auctioned or assigned spectrum licences with defined areas, terms and conditions, used for public mobile networks.

4. Architecture · Spectrum, timing and PNT

   Spectrum monitoring and interference management

   In Positioning, navigation and timing, the spectrum monitoring and interference management layer holds fixed, transportable and mobile monitoring stations, spectrum occupancy measurement and emitter location, each drawn against the standard it follows. Calibrated receivers and antennas that measure what is actually on air around a site or region.

5. Architecture · Spectrum, timing and PNT

   Resilient PNT

   In Positioning, navigation and timing, the resilient PNT layer holds resilient PNT frameworks, terrestrial radionavigation and time over fibre, each drawn against the standard it follows. Structured ways to assess and raise how well equipment resists, detects and recovers from PNT disruption.

6. 运作方式

   From instrument to record

   In a network for Positioning, navigation and timing, the base node stands between the instrument and the link: it checks each value, stamps its time and place and signs it. The edge refuses any record for Positioning, navigation and timing whose signature fails, and the core keeps every admitted record with its metadata, its quality flag and its licence.

7. 信任

   Proved before it is trusted

   A network for Positioning, navigation and timing admits a node only once its hardware root of trust has answered an attestation challenge, whoever supplied it. Signed software, keys kept in secure hardware and a signature on every record let anyone check where a value for Positioning, navigation and timing came from.

8. Architecture · Spectrum, timing and PNT

   Grandmasters, reference clocks and holdover

   In Positioning, navigation and timing, the grandmasters, reference clocks and holdover layer holds PRTC and enhanced PRTC, primary reference clocks for frequency and atomic and quartz oscillators, each drawn against the standard it follows. GNSS-traceable time references at 100 ns or 30 ns accuracy that anchor a timing network.

9. Architecture · Spectrum, timing and PNT

   Interference, jamming and spoofing detection

   In Positioning, navigation and timing, the interference, jamming and spoofing detection layer holds GNSS interference monitoring, spoofing detection and jammer location to support enforcement, each drawn against the standard it follows. Fixed sensors that detect and characterise GNSS interference near critical sites; detection and reporting only.

10. Failure and recovery

    When a node fails, the fleet knows first

    A failure on a network for Positioning, navigation and timing is caught by the fleet before anyone reports it: the node buffers its data and fails over where it can. The responder for Positioning, navigation and timing gets the evidence with the alert, and the record neither loses data nor counts it twice.

11. Architecture · Spectrum, timing and PNT

    Packet timing: PTP, SyncE and NTP

    In Positioning, navigation and timing, the packet timing: PTP, SyncE and NTP layer holds Precision Time Protocol, telecom profile with full timing support and telecom profile with partial timing support, each drawn against the standard it follows. The base protocol for distributing time and phase over packet networks.

12. What you get

    Open where it can be, contracted where it must be

    What is open for Positioning, navigation and timing is free: the protocol, the methods and the open data can be used and built on by anyone. What must be contracted for Positioning, navigation and timing, sites, fleets, managed operations and data tiers, Nexus Observatory Inc. delivers at a price per site and per fleet, with service levels in numbers.

    Positioning, navigation and timing, planned with you

    Tell us which layers of Positioning, navigation and timing you already run and which you want us to design and deliver. 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.

01Reference architecture

From one instrument to the grid.

Every deployment is drawn on the same six layers. A typed contract sits at every boundary, so parts from different makers fit together.

1. 01InstrumentThe sensor or radio that makes the measurement, with its calibration.
2. 02NodeThe device that hosts instruments: identity, time, power and storage.
3. 03站点Nodes in one place, on one mast or in one shelter, with their links.
4. 04CellSites that share a backhaul, a power plan and an operator.
5. 05ClusterCells run as one service, with one fleet plan and one evidence trail.
6. 06GridClusters that federate across owners through the open protocol.

The protocol functions this platform relies on most.

02Trust and evidence

Every observation carries its proof.

What a buyer, a regulator or a partner grid can check, on every site we build.
