GP PROBE NANO L1
DETECT. LOG. LOCALISE. REACT.
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.
The Nano L1 provides early warning, reliable evidence, and precise localization tools.
Law Enforcement & Security
Detect jammers, log evidence, and improve operational safety.
Military
Enhance spectrum awareness and detect GNSS threats in contested environments.
Fleet Management
Prevent GPS jammer abuse and maintain tracking integrity.
Critical Infrastructure
Monitor GNSS reliability across airports, utilities, and communications hubs.
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.
Find Out HowExposing 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.
GPS Jamming Detection = Early Warning for VIP Protection
Before most attacks on convoys or protected individuals, RF jammers are switched on—blocking GPS and cellular signals and cutting off situational awareness at the worst moment.
What many teams miss: this jamming is detectable. Because it happens seconds or minutes before an attack, it creates a critical window to act.
The GP-Probe Nano L1 doesn’t stop the threat—but it gives something most teams don’t have: warning time.
When a jammer activates nearby, the device alerts instantly (vibration, sound, LED). That signal means one thing: something in the RF environment isn’t right.
Those seconds enable action:
- Switch routes
- Move to non-GPS navigation
- Alert ops via radio
- Shift to a heightened security posture
Without detection, the first sign of trouble is the attack itself.
Lightweight (50g), 30-day battery, no setup, no RF expertise required—just continuous monitoring and real-time alerts.
Find Out HowThe Nano L1 is more than a detector—it’s a proactive defense tool for organizations that rely on GNSS integrity. By combining portability, precision, and real-time analytics, it enables faster decisions, stronger compliance, and greater operational confidence.
If GNSS reliability matters to your mission, the Nano L1 is an essential addition to your toolkit.
