Timing and satellite signal monitoring

Reliable time and GNSS monitoring for critical infrastructure

We help essential services check that the clocks and satellite signals they depend on are reliable, detect disruption, and respond with confidence.

Why timing matters

Modern infrastructure runs on trusted time

Accurate time is not just about knowing the hour. It lets equipment agree on when events happen.

Mobile networks use precise time to coordinate communications, electricity networks to compare measurements, and financial systems to record transactions accurately. Transport, cloud services, and emergency systems also depend on trusted timing.

Many systems obtain precise time from GPS and Galileo. These satellite navigation systems are collectively known as GNSS. If their signals are blocked, manipulated, or degraded, the equipment using them may no longer have a reliable reference. We independently monitor these sources so operators can see when something is wrong.

The risk

GNSS disruption is no longer a remote problem

A timing-dependent system may appear to be running normally while its reference source is degraded, manipulated, or drifting.

GNSS jamming

Intentional or accidental radio interference can block satellite signals and remove a trusted timing source.

Spoofing

False signals can mislead receivers, creating incorrect position or timing data that looks plausible.

Interference

Local radio noise, poor installation, or weak reception can degrade timing quality without immediate failure.

Timing drift

Equipment can continue operating while its local clock moves away from the trusted reference.

Lack of visibility

Without independent monitoring, teams may not know whether GNSS and timing sources are still reliable during an incident.

What we provide

From signals to decisions

Independent checks turn timing and satellite observations into information your team can act on.

Monitor

Observe satellite signals and timing sources at the sites that matter to you.

Compare

Check observations against trusted references and independent data to identify inconsistencies.

Alert

Notify your team when monitoring identifies degraded signals or timing anomalies.

Review

Use recorded observations to investigate incidents and support operational decisions.

Sample monitoring dashboard with site locations, OK, warning and alert states, and a health-state timeline
Example dashboard, not a live feed. Site locations show where monitoring takes place; status indicators show reported health; the timeline helps review changes over time.
Illustrative incident

A satellite timing source becomes unreliable. What happens next?

Monitoring identifies an anomaly, your team receives an alert, and recorded observations help establish where and when the change occurred. Operators can then investigate and follow their incident procedures. Monitoring provides evidence; it does not itself repair the source or switch equipment to a backup.

Benefits

For companies that depend on accurate timing

Reliable monitoring gives operational teams the evidence they need to protect services, reduce uncertainty, and respond faster when GNSS or timing sources become unreliable.

Detect disruption early

Spot GNSS interference before it affects operations or users.

Reduce outage risk

Protect systems that depend on accurate timing and synchronisation.

Support resilience requirements

Use monitoring, alerting, and auditable data for NIS2 and critical infrastructure obligations.

Extend equipment life

Improve existing GNSS timing infrastructure before replacing hardware.

Strengthen audit evidence

Provide data for audits, incident reviews, compliance reporting, and internal assurance.

Respond better during incidents

Give operators visibility during jamming or spoofing events so they can act faster.
