Would your organisation cope if GNSS went down?

Answer 14 questions about how you prepare for, respond to and recover from a GNSS outage. You get a score, your weakest stage and your first three actions. Your answers stay in your browser.

STAGE 1

Prepare

Know what depends on GNSS, what losing it would do, and who owns the risk.6 questions
P1Do you know every system that uses GNSS position or time?

Including systems inside your suppliers' services.

P2For each of those systems, do you know what happens if GNSS is lost?

From the first minute to a month-long outage.

P3Is GNSS loss on your risk register, with a named owner?

Jamming, spoofing and plain outages all count.

P4Do you know how long each system can run without GNSS?

Holdover for clocks, drift for navigation.

P5Have you asked your suppliers how their services cope without GNSS?

Telecoms, cloud, tracking and timing providers.

P6Do your critical systems have a backup source of position or time?

For example inertial sensors, a holdover clock or a second timing feed.

STAGE 2

Act

Spot a disruption quickly and keep essential operations running safely.4 questions
A1Would you notice quickly if GNSS was being disrupted?

Before customers or operators tell you.

A2Do staff know what to do when GNSS is lost?

A short written procedure they can find in a hurry.

A3Can essential operations keep running safely without GNSS?

Reduced capacity is fine, as long as it is safe.

A4Have you practised a GNSS outage?

A tabletop exercise counts.

STAGE 3

Recover

Return to normal safely, learn from it, and keep improving.4 questions
R1Do you know how to confirm GNSS can be trusted again?

A receiver showing a fix is not proof on its own.

R2Is there a safe order for bringing systems back?

Some systems need others to be right first.

R3Do you record GNSS incidents and report them?

Internally, and to whoever regulates or oversees you.

R4Do you review incidents and update your plans?

Near misses included.

Indicative self-assessment, not an audit or certification. Structured around the three stages in the Royal Institute of Navigation’s Resilient PNT Best Practices (prepare, act, recover). The questions and scoring are Bearing & Fix’s own and are not endorsed by the RIN.
