Key Features Specification Ordering Information Resources

Key Features

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.

Three-in-One Solution

The combination of three functions: interference detection, PPS accuracy and signal quality monitoring makes the device perfect for ensuring reliable synchronization of 5G infrastructure.

Onboard RF Blocker

In the event of spoofing detection or signal quality degradation, the integrated RF switch and GNSS jammer will block your GNSS receiver, ensuring high synchronization accuracy in any GNSS interference scenario.

PPS Accuracy Monitoring

GP-Probe DIN1 measures the time offset between internal and external PPS and streams the data to GP-Cloud for real-time monitoring, statistical analysis, and user notifications.

Cyber-Safe, 24/7

GP-Probe utilizes a secure, Non-Linux, real-time operating system that is immune to cyber threats. The combination of built-in hardware fault monitoring and a secure firmware update engine ensures continuous 24/7/365 critical infrastructure defense.

Embedded Lua Scripting

Develop custom scenarios for external equipment remote control via RS232/Telnet/SNMP with the embedded LUA scripting engine.

Easy-to-Install

The device is installed and configured in minutes thanks to the DIN-compliant mounting and the integrated Web Configuration Panel
