GNSS interference is no longer a rare technical anomaly—it is a growing operational risk for law enforcement, military units, fleet operators, and critical infrastructure providers.
The Nano L1 Wearable GNSS Jamming Detector delivers a compact, field-ready solution for identifying, logging, and analyzing GPS L1 interference in real time.
Small enough to fit in a pocket yet powerful enough for professional deployment, the Nano L1 provides continuous situational awareness wherever GNSS reliability matters most.
Whether deployed independently or paired with an Android device and GP-Cloud, the Nano L1 equips teams with actionable intelligence to respond quickly and effectively to jamming threats.
Why GNSS L1 Monitoring Is Mission-Critical
GNSS signals underpin modern navigation, timing, and tracking systems. When interference occurs—whether accidental or intentional—the consequences can include:
Loss of vehicle tracking visibility
Disruption to operational coordination
Compromised security and surveillance systems
Safety risks in high-value or sensitive locations
Regulatory and compliance violations
The Nano L1 is designed to give operators early warning, reliable evidence, and preciselocalization tools to protect GNSS-dependent operations.
Built for Law Enforcement and Security Operations
For police, border control, and security agencies, GPS jammers are increasingly used to evade tracking or obscure criminal activity. The Nano L1 enables officers to:
Rapidly detect unauthorized GNSS jammers in vehicles or facilities
Log interference events for investigative evidence
Identify patterns of jammer usage across locations
Enhance operational safety during active deployments
With real-time alerts and autonomous logging, teams can monitor environments continuously without adding operational complexity.
Trusted by Military Operators in Contested Environments
Military operations depend heavily on reliable positioning and timing data. The Nano L1 strengthens operational readiness by:
Providing early detection of GNSS interference threats
Supporting spectrum awareness in contested environments
Enabling post-event forensic analysis
Assisting with passive localization of interference sources
Its wearable, lightweight design ensures minimal burden on personnel while delivering critical electronic awareness.
Essential for Fleet Management and Compliance
Fleet operators face increasing challenges from drivers using GPS jammers to bypass tracking systems. The Nano L1 empowers organizations to:
Detect jammer usage in real time
Protect asset visibility and route integrity
Enforce compliance with company policies
Reduce liability and operational blind spots
By identifying interference early, companies can maintain accountability and ensure uninterrupted fleet monitoring.
Safeguarding Critical Infrastructure
Airports, seaports, power plants, and communications hubs rely on stable GNSS signals for daily operations. The Nano L1 provides:
Continuous interference monitoring near sensitive sites
Early alerts to prevent navigation disruptions
Data-driven insights for incident response
Long-term trend analysis of interference hotspots
This proactive monitoring helps organizations maintain operational continuity and safety.

Convoy Jamming Alert
Most convoy attacks begin with RF signal jamming.
The moment navigation and communications are disrupted, the attack is already underway.
Those first seconds are critical.
Early detection gives security teams the time they need to react, reposition, and prepare.
This is exactly what GP-Probe Nano is designed for.
. Ultra-compact, wearable GNSS jamming detector (GPS L1)
. Instant alerts: sound, vibration, and multi-level LED scale
. Standalone operation or Android smartphone connection via USB-C
. Up to 30 days battery life in detector mode
. Event logging for investigations and reporting
. Optional GP-Cloud integration for team operations
🎯 Detect jamming early. Gain seconds that change the outcome.
Exposing an Illegal Luxury Car Scam
Most people don’t realize how GPS jammers are used in car theft.
When a vehicle is stolen, criminals often activate an RF jammer immediately.
Their goal is simple: block any hidden tracker from reporting the car’s location.
The jammer stays on as the vehicle is transported to a secure, hidden location.
Only once the car is dismantled—and they’re confident no tracker remains—do they switch it off.
But here’s the twist:
A jammer designed to hide the crime…
actually creates a signal that can be detected.

Inspired by a real incident at Warsaw Airport.
A small portable jammer.
A highly sensitive aviation environment.
GNSS signals are inherently weak. Even a low-power jammer can disrupt satellite navigation within seconds.
Airports depend on GNSS for:
. Aircraft approach monitoring
. Ground movement systems
. ADS-B surveillance
. Communication networks
. Time synchronization
. Emergency coordination
. Security and fleet operations
Whether intentional or accidental, GNSS interference creates serious operational and safety risks.
GP-Probe Nano detects jamming instantly — enabling rapid response and source localization.
Detection restores awareness.
Awareness enables response.
