GP-Probe Nano

Instant alerts when jamming is nearby.
In this mode, the device continuously scans for RF interference in the GNSS L1 band and immediately notifies you using sound, vibration, and an LED scale. It’s perfect for walk-around inspections or personal GNSS protection — giving you real-time situational awareness with zero setup.

Unattended monitoring and detailed post-analysis.
This silent mode records interference power once per second, running autonomously for up to 3 months. Ideal for long-term or covert deployments, you can later retrieve all logs to analyze when and where jamming occurred — even if you weren’t present during the event.

See interference and GNSS signal health in real time.
This mode shows live charts of RF power and GNSS SNR directly on your smartphone. It helps you instantly detect and understand the impact of jamming on signal quality — a powerful tool for diagnostics and site surveys.

Quickly estimate the direction of a jammer — without extra gear.
By using your own body as a passive shield, you can rotate with the device and let the app detect where the interference is coming from. Direction vectors are shown on the map to help you pinpoint the source quickly and easily — even without a directional antenna.

Detect and classify jammers while driving.
Mounted in a vehicle, the system automatically detects jamming signals on the move, classifies them, and logs where they occur. You get a geotagged timeline of events — perfect for route analysis or tracking moving threats.

Monitor a fixed location for passing interference.
Place the device roadside or at a facility perimeter, and it will watch for jamming from nearby vehicles. Events are automatically recorded and can include a photo — providing visual evidence alongside RF data for investigations.

Find the jammer faster with multiple users.
Multiple devices submit their direction estimates to the cloud, where the system calculates the source location by intersecting vectors — dramatically speeding up localization and improving accuracy.

Build a shared threat map across your fleet.
As your vehicles detect interference, all data is synced to the cloud in real time. Your team gets a live view of jamming activity across a wide area — helping you spot trends, repeat offenders, and movement patterns.

Centralized surveillance with optional images.
All stationary events are logged and uploaded, including optional photos. From a central dashboard, your team can analyze multiple monitoring points, correlate data, and respond faster to threats.
