Coordinates and time a whole country can trust.

Every survey, map, cadastre, construction project and timed network in a country relies on the national reference frame and national time. Reference stations must be stable for decades, run continuously and tie to the global frame. The network is built and run for that.

1. Government · Geodetic reference and national timing

   Every map starts from here

   Surveys, maps, cadastres, construction, farming guidance and timed networks all rely on the national reference frame and national time. Reference stations define that frame and must stay stable and continuous for decades. Countries are asked to sustain the global frame, and a national network built for it serves every user.

2. What is measured

   Signals, weather and time

   Geodetic receivers on stable monuments track every satellite signal each second. A meteorological sensor beside each antenna supports atmospheric delay modelling, and timing receivers compare national time with satellite time. Every antenna, receiver and height is recorded in the station log.

3. The base node

   Clocks held at the station

   The node streams observations, writes daily archive files and watches signal quality for interference. When satellite time is lost, it holds time from its reference and reports how far it may have drifted, so networks that depend on it know what to trust.

4. Radio and links

   Two paths for every stream

   Stations at agency buildings and towers stream over fibre to the positioning service. Cellular is a second, independent path, so corrections continue when the fibre is cut. Daily files and logs reach international services, and time reaches operators through the national time service.

5. How it works

   From a satellite signal to a survey

   A surveyor sets up on a building site. The nearest reference stations stream their observations, the positioning service computes corrections, and the surveyor’s receiver fixes its position in the national frame within seconds, consistent with every other survey in the country and with the global frame.

6. From order to operation · Order

   Scope the frame and its users

   The scope reads the existing reference stations, the national frame and its tie to the global frame, the positioning services and their users, and the time service. Nexus Observatory Inc. returns a station plan, the processing and archive design, timing outputs and a price per station and per year.

7. From order to operation · Survey

   Survey for stability

   Crews and geodesists visit candidate sites for stable ground or buildings, a clear sky view, low multipath, no interference sources, power and two backhaul paths. Each candidate is tested with a temporary receiver before a monument is chosen. Findings shape the kit for each site before anything is built.

8. From order to operation · Permits

   Land and radio

   Agreements for long-term land or roof use are signed with owners, radio spectrum for any correction broadcasts is licensed, and building owners approve antenna masts. Every agreement is kept with the station record, because reference stations must stay put for decades.

9. From order to operation · Build

   Build monuments and kits

   Monuments are designed for the ground at each site; receivers, antennas, meteorological sensors and nodes are tested together, enrolled with their identities and logged with serial numbers so every later change can be recorded in the station log. Nothing ships until the whole kit has passed its tests together.

   Open the Station Builder

10. From order to operation · Install

    Install the monument and antenna

    Crews build the monument, mount the antenna with its orientation and height measured, install the receiver, meteorological sensor and node in the shelter, and connect both backhaul paths. Every measurement goes into the station log in the international format. Crews follow the site safety plan throughout the work.

11. From order to operation · Commission

    Commission against the frame

    Each node proves its identity. Weeks of observations are processed to fix the station’s coordinates in the national and global frames, streams are tested with the positioning service, and the timing output is compared with the national time reference. Acceptance is recorded with the owner before handover.

12. From order to operation · Operate

    Hold the frame

    The agency sees every station streaming, daily solutions, signal quality and interference events. Surveyors and builders receive real-time corrections, networks receive time, and the frame is updated as the global frame is, with every station’s motion known. Every alert and action is kept on the record.

13. From order to operation · Maintain

    Log every change

    Receivers and antennas are changed only with a log entry and overlapping observations, monuments are inspected, software updates roll out in rings, and interference is reported to the spectrum regulator. The station logs keep the time series usable for decades.

    A frame that lasts decades

    Stations follow the international site guidelines, coordinates are computed in frames defined by the international conventions, the network supports the UN resolution on the global geodetic reference frame and time is traceable to UTC. Every change is logged, so the series stays usable for decades.

01The place and its hazards

Where it runs, and what can go wrong.

Operating contextNational mapping and geodetic agencies run continuously operating reference stations that define the national frame, support positioning services and tie the country to the global geodetic reference frame. Countries are asked to sustain that frame, stations follow international site guidelines, and national time services hold their clocks to Coordinated Universal Time.

Hazards

• Monuments that move with the ground they stand on
• Receivers and antennas changed without records, breaking time series
• Interference and jamming of satellite signals
• Outages that interrupt positioning services
• Clocks that drift when satellite time is lost

02What must be measured

What, where, how often, and under which rules.

Each measurement names where it is taken, how often, and the public standard or regulation behind it. Numbers in the sources column open the cited source below.

03The observation stack

From one base unit to a network.

The same blocks at every scale: instruments and a base node, a site with its radio, a fleet run as one, and a network federated on the open protocol.

Radio and links

Fibre

Stations at agency buildings and towers use fibre for real-time streams to positioning services.

Radio and links

Public cellular

Cellular is the second path, so streams continue when the fibre is cut.

Edge computeThe node streams observations to the positioning service, writes the daily archive files, watches signal quality and interference, and holds time from the reference when satellite time is lost.

PowerMains with a battery that rides through outages so the time series has no gaps; remote stations run on solar with enough storage for the darkest weeks.

07Questions buyers ask

Before you scope it.

Will the stations change our frame?

No. They are tied to the national frame and updated only when the agency decides.

Can receivers be replaced later?

Yes, with log entries and overlapping observations so the series stays continuous.

Do you detect jamming?

Each receiver reports signal quality and interference events.

Who owns the data?

The agency. Sharing follows its own policy.
