GP-Probe NANO L1

GP-Probe Nano L1 is a highly compact and portable GNSS jamming detector engineered for identification and logging of interference within the GPS L1 band. Utilizing advanced power measurement techniques with huge dynamic range, the device continuously monitors interference power, and alerts users to potential jamming threats. Designed for versatility, it can operate autonomously using its built-in battery and alert system (speaker, vibration, and LED scale) or be connected to an Android smartphone via USB Type-C for enhanced real-time data visualization, analysis and streaming to GP-Cloud. The small form factor, roughly the size of a flash drives, makes it ideal for field use, security applications, and interference investigations.

Key Features
Dual Operation Modes:

• Detector Mode: Monitors signal power 10 times per second and instantly alerts users to potential jamming events.
• Logger Mode: Runs fully autonomously for up to 3 months, recording power levels every second. All measurements are stored and can be later transferred to an Android app for detailed analysis.

• Enables real-time monitoring of power levels and GNSS signal quality (e.g., SNR).
•  Allows users to retrieve and analyze logged data.
• Supports multiple smartphone-assisted modes:
  • Monitoring Mode – live signal and interference visualization.
  • Patrol Mode – mobile jammer detection with classification and geotagging.
  • Sentinel Mode – stationary roadside monitoring with optional photo capture.
• Optional GP-Cloud integration for collaborative localization and event sharing.

• Real-time synchronization of interference events across multiple users.
• Supports collaborative modes:
  • Collaborative Localization Mode – triangulate jammer position using directional data from several detectors.
  • Collaborative Patrol Mode – share mobile detection events and jammer classifications.
  • Collaborative Sentinel Mode – upload stationary monitoring data and optional images for remote analysis.
• Enables centralized analysis, team coordination, and remote access to all logged data.

High Sensitivity: Detects GNSS jamming up to 200 meters in line-of-sight conditions from a 5 dBm USB-powered jammer. Detection range is 50-70 meters when the jammer is installed inside a vehicle, depending on shielding and propagation conditions.

Wide Dynamic Range: Covers 5 dBm to -100 dBm, ensuring detection of both low-power and high-power jammers. Enables reliable identification of interference sources across short and long distances, adapting to varying signal environments.

Notification System: Utilizes a built-in speaker, vibration, and a 36-LED scale to alert users about detected interference in real-time and it’s power.

Compact & Lightweight Design: Its form factor is comparable to a flash drive, making it easily portable for field operations.

Extended Battery Life:

• Up to 1 month in Detector mode (10 measurements per second).
• Up to 3 months in Logger mode (1 measurement per second).

One-Button Simplicity: A single button on the device controls power, notification muting, and battery status check, ensuring intuitive operation in any environment.

Angle-of-Arrival Estimation: By leveraging natural body attenuation effects, users can determine the approximate direction of interference sources without requiring a directional antenna.
