**Satellite ground stations** 

# Ground stations, ready for every pass.

A satellite ground station has minutes for each pass and loses signal in heavy rain. Weather sensors at the antennas, condition monitoring on antenna drives, timing references and site security report to one record that schedules passes around the weather and catches faults between them.

**Industry**: Telecom
**Measurements**: 5

1. Telecom · Satellite ground stations Minutes per pass, lost to the rain A satellite crosses the sky in minutes, and a heavy shower over the station can wash out the link at higher frequencies. Antennas stop in high wind, and a worn drive can fail mid-pass. Measuring rain, wind and drive health at every antenna lets operators plan each pass and catch faults between them.
2. What is measured Rain, wind, drives and time Rain gauges beside each large antenna measure rain rate, anemometers at antenna height measure wind, and vibration sensors on motors and gearboxes follow drive health during motion. GNSS-disciplined references keep station time, and cameras watch pads and gates. Every reading names its antenna. InstrumentsRain gauges · Anemometers · Drive vibration · GNSS timing · Cameras
3. The base node Fade predicted for every pass The station node predicts rain fade for each coming pass from the rain rate and the link frequency, flags antennas to stow in high wind, detects drive faults from vibration during motion and time-stamps every pass log against the GNSS reference.
4. Radio and links Fibre home, and the sky as a spare Ground stations are connected by fibre to their networks, and monitoring rides that fibre. When terrestrial links fail, the station's own antennas or a small terminal carry the alarms, and an out-of-band cellular path is used where coverage exists. Each path is supervised. LinksFibre · Satellite · Public cellular
5. How it works From a shower to a moved pass A heavy shower approaches the station before a critical pass. Rain gauges read the rate rising, the node predicts the fade at the link frequency and alerts the scheduler, who moves the pass to a station in clear weather. The pass log records the weather and the decision.
6. From order to operation · Order Scope the station and its passes The scope reads the antennas, frequencies, pass schedule, weather history, timing and security arrangements. Nexus Observatory Inc. returns the point plan per antenna, the rain fade prediction method, the integration with scheduling and a price per station and per year. [Plan a deployment](https://observatory.global/contact/deployment/)
7. From order to operation · Survey Survey around the antennas Crews survey each antenna with the station engineer: gauge and anemometer sites clear of the dish, drive access for vibration sensors, timing references and camera views over pads and gates. They record fibre, power and lightning protection. Every candidate site is photographed for the design.
8. From order to operation · Permits Licences and site rules Nothing new may radiate or interfere with the station's licensed operation. Work on antennas follows the station's safety and outage rules, and every approval is kept with the station record. Sensors are checked so that nothing new radiates in the station’s bands. Work on antennas follows the station’s outage plan, so no pass is lost to installation.
9. From order to operation · Build Build for the antenna pad Rain gauges, anemometers, vibration sensors, cameras, the timing reference and nodes are built, tested together and enrolled with their identities. Each antenna's frequencies and stow limits are configured, and every part is labelled by antenna. Configurations are tested on the bench with the scheduler interface before shipping. [Open the Station Builder](https://observatory.global/studio/builder/)
10. From order to operation · Install Install between passes Crews install between passes: gauges and anemometers beside each antenna, vibration sensors on drives, cameras over pads and gates and the timing reference in the equipment room. Cables are protected against lightning, and every point is photographed. Each antenna returns to service before its next pass.
11. From order to operation · Commission Check against a real pass Each node proves its identity. Gauges are checked with a measured volume, anemometers against a reference, drive vibration baselines are taken on healthy antennas, and rain fade predictions are compared with received signal on real passes. Results are kept with the antenna record.
12. From order to operation · Operate Schedule around the weather Schedulers see predicted rain fade for each pass and move critical passes to stations in clear weather. Antennas stow when wind limits are reached, drive faults are planned for repair between passes, and every pass log carries its weather and timing.
13. From order to operation · Maintain Maintain in pass gaps Sensors are checked during antenna maintenance windows, gauges cleaned, drive baselines updated after repairs, and the timing reference checked against GNSS. Every change is recorded with the antenna, so pass and availability records stay complete. Spares are kept on site for quick swaps between passes. [Book field services](https://observatory.global/contact/field-service/)
14. Data products For schedulers, operators and customers Pass schedulers receive rain fade predictions; station operators receive wind stow alerts; maintenance engineers receive antenna drive health; operators and customers receive pass logs with weather and timing. Each product carries its antenna, frequency and time. Reports are dated and versioned. [See the data products](https://observatory.global/data-products/)
15. Evidence Availability on record Every reading, prediction, pass and fault is signed and kept. Rain fade follows the ITU propagation recommendations, rain characteristics follow the ITU precipitation model, weather follows WMO practice, and operation follows the radio regulations and the station's licence. Records are open to customers. Drawn againstITU-R P.618 · ITU-R P.837 · WMO-No. 8 · ITU Radio Regulations

**01** The place and its hazards

## Where it runs, and what can go wrong.

Operating contextGround stations track satellites through passes, uplinking commands and downlinking data, often unattended and far from towns. Rain attenuates higher-frequency links, wind limits antenna operation, lightning threatens equipment, and timing must be accurate. Propagation prediction follows ITU recommendations, and stations operate under radio regulations and their licences.

Hazards

- Rain fade losing passes at higher frequencies
- High wind stopping antennas
- Lightning damage
- Antenna drive and bearing faults
- Unattended sites open to intrusion

**02** What 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.

| Measurement | Where | Cadence | Sources |
| --- | --- | --- | --- |
| Rain rate | Gauges beside each large antenna | Continuous, at short intervals | 12 |
| Wind speed and gusts | Anemometers at antenna height | Continuous | 3 |
| Antenna drive condition | Motors, gearboxes and bearings | Continuous during motion | 4 |
| Time and frequency reference | GNSS-disciplined references | Continuous | 4 |
| Site access and images | Gates, shelters and antenna pads | On event | 4 |

**05** From order to operation

## Every step, from the first call to a running site.

The same crew and the same record carry the work from scope to maintenance.

1. 01 Order Scope the station and its passes The scope reads the antennas, frequencies, pass schedule, weather history, timing and security arrangements. Nexus Observatory Inc. returns the point plan per antenna, the rain fade prediction method, the integration with scheduling and a price per station and per year. 2

3. 03 Permits Licences and site rules Nothing new may radiate or interfere with the station's licensed operation. Work on antennas follows the station's safety and outage rules, and every approval is kept with the station record. Sensors are checked so that nothing new radiates in the station’s bands. Work on antennas follows the station’s outage plan, so no pass is lost to installation. 4

## Before you scope it.

How is rain fade predicted?

From measured rain rate and the link frequency, using the ITU propagation methods.

Will sensors interfere with the antennas?

Nothing radiates in the station's bands, and sites are chosen clear of the dish.

Can passes move to another station?

Yes, where the network has one in clear weather; the scheduler decides.

What timing is used?

GNSS-disciplined references at each station.
