GP-Probe DIN L1

The GP-Probe DIN L1 safeguards your GNSS-dependent systems from spoofing, jamming, and GNSS signal quality degradation. This in-line device seamlessly integrates between your GNSS antenna and receiver, providing real-time monitoring and defense.

 

GP-Probe DIN L1 covers three primary applications: GNSS interference detection and classification, PPS accuracy monitoring, GNSS signal quality analysis, and logging. The device is easily installed between a GNSS antenna and a receiver or time server. When an event is detected, the GNSS and PPS outputs are immediately disabled, preventing any counterfeit signals from reaching your systems.

With Onboard Signal Processing option, GP-Probe DIN L1 can detect GNSS interference and anomaly without connecting to GP-Cloud.

Key Features:

  • Interference detection, PPS accuracy and signal quality monitoring
  • Onboard RF Blocker In the event of spoofing & Jamming detection or signal quality degradation

  • Supported Any combination of constellations- GPS L1 C/A, GLONASS L1, BeiDou B1I/B1C, Galileo E1B/C
  • One GNSS RF channel for interference/anomaly detection and signal quality analysis
  • Detected Threat Types: Interference in 60 MHz band, asynchronous spoofing, synchronous spoofing with high power
  • Displays GP-Probe status, GNSS channel status: satellites in view, RMS CN0 and Server settings and status
  • Cost-effective GNSS probe with built-in RF blocker
  • RF spectrum analyser
  • Supported by GP-Cloud to provide centralized monitoring of your entire GNSS-dependent infrastructure

GP-Probe TGE2

GP-Probe TGE2 covers three primary applications: GNSS interference detection and classification, PPS accuracy monitoring, GNSS signal quality analysis, and logging.

 

The GP-Probe TGE2 is designed to protect time servers (PNT) against a GNSS threat such as cutting-edge intentional spoofing, jamming, ionospheric scintillation, system errors, for example. An embedded PPS phase error

measurement function enables the reliable monitoring of the time server’s health. The GP-Probe, in conjunction with the GP-Cloud, allows developing a robust and resilient clock synchronization system for critical infrastructure.

The GP-Probe measures GNSS satellite signals on 3 channels and transmits raw data to the GP-Cloud for real-time processing.

Key features:

  • Three RF channels for intentional, synchronous, multiple-TX GNSS spoofing detection.
  • 60 MHz real-time RF signal analyzer for spectrum monitoring, interference classification and localization
  • GNSS signal quality measurements: pseudo range errors, carrier phase, SNR, etc.
  • Support GNSS: GPS/QZSS L1 C/A, GLONASS L10F, BeiDou B1I, Galileo E1B/C, SBAS L1 C/A: WAAS, EGNOS, MSAS, GAGAN
  • The embedded real-time operating system FreeRTOS guarantees high availability and cybersecurity.
  • PPS input for the external time server health checking.
  • Optional GP-Blocker with an embedded GNSS jammer suppresses the most powerful counterfeit RF signals.
  • Secure firmware auto-update engine.
  • Embedded self-diagnostic and dispatching all error messages to the cloud.
  • PPS output for synchronization of external equipment.
  • Optional RF power divider – GP-Divider enables to utilize one GNSS antenna for two receivers.
  • Form factor: 19-inch rack, half-size.
  • Dual power module: 110 – 220 AC, 18 – 75 DC.
  • Active/passive GNSS antenna support.
  • 4G modem and 100BASE-TX Ethernet for data transferring to the GP-Cloud.
  • Web interface for configuration.
  • External devices can be controlled via remote interfaces: RS-232/RS-485/RS-422

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:

  • 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.
  • Android App Integration:
    • 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.
  • 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
