Detect GNSS jamming & spoofing in real time

GNSS‑Shield EU is an edge‑to‑cloud monitoring platform that spots interference on GPS/Galileo, verifies OS‑NMA authenticity, triangulates hostile emitters, and generates ready‑to‑sign compliance reports (NIS2/EASA).

Sub‑second edge alerts

Galileo OS‑NMA ready

TDOA triangulation

Edge probe detects a multi‑tone jammer in 1.7 s and auto‑uploads a 3‑second IQ clip for forensics.

EU-native

NIS2 Reporting

EASA Awareness

Galileo OS-NMA

Edge-first

API‑ready

Built for critical infrastructure

Designed with airports, power grids, telecom and rail operators in mind—secure by default, low bandwidth, and battle-tested DSP.

Real‑time interference detection

Edge probes compute FFT/CN0/kurtosis to detect wideband, multi‑tone and chirp jammers in sub‑seconds.

Spoofing & OS-NMA verification

Detect code/Doppler inconsistencies and verify Galileo OS-NMA authenticity when SNR allows.

Multi-site triangulation

Cross‑correlate events across probes to localize emitters via TDOA/MLAT within minutes.

Compliance, automated

Generate audit-ready reports (NIS2/EASA) with evidence: timelines, IQ clips, site posture and MTTR.

Edge-first, low bandwidth

Only features stream to the cloud; IQ is captured on incident windows for forensics—saving bandwidth and protecting privacy.

Easy integration

Webhooks, MQTT, syslog and REST/GraphQL APIs connect to your SOC, SIEM, or SCADA in hours—not weeks.

Who it's for

Protect GNSS-dependent operations across critical sectors.

Aviation

Regional airports, ANSPs, and airlines monitoring RNP/LPV operations and GNSS outages.

Energy

TSOs/DSOs securing PMU timing and substation resilience.

Telecom

5G timing hubs and core networks ensuring PTP/GNSS sync integrity.

Rail

ETCS L3 deployments with GNSS-assisted train location.

Ports & Maritime

Harbor operations, pilotage and coastal navigation.

Datacenters & Finance

UTC traceability for trading and DCs with GNSS timing.

How it works

From edge probe to actionable alert in four steps.

1
Deploy probes

Install low-cost SDR probes with GNSS antennas on rooftops.
2
Analyze on edge

Probes compute features (FFT, CN0, Doppler, entropy) and flag anomalies.
3
Correlate in cloud

Cross-correlate events across sites, localize emitters, reduce false positives.
4
Alert & report

Trigger webhooks/MQTT/SIEM, archive IQ clips, and generate compliance PDFs.

Trusted by critical operators

What early users say about GNSS-Shield EU.

"We detected two rogue jammers near our perimeter within a week. The TDOA map guided our security team straight to the source."

Head of Security, regional airport

"The OS-NMA checks and audit-ready reports cut our NIS2 paperwork in half."

FAQ

A few practical details before you start.

Is it legal to deploy GNSS probes?

Yes—probes are passive receivers. We also provide guidance to coordinate with your national spectrum authority if needed.

What about data privacy and bandwidth?

By default we only stream features (few kbit/s). IQ is captured as short, encrypted incident clips for forensics.

Do you support Galileo OS-NMA?

Yes. When SNR allows, we verify OS‑NMA to authenticate the navigation message and reduce spoofing risk.

How accurate is the triangulation?

With three or more probes and good timing sync, TDOA/MLAT typically narrows to a city block scale in urban terrain.

Can we integrate with our SOC/SIEM?

Absolutely—webhooks, syslog (CEF/LEEF), MQTT, and REST/GraphQL APIs are available. SSO/SCIM on Enterprise.

Where can you deploy?

We start in the EU and UK. On-prem and air-gapped options are available for sensitive environments.
