Key Features

3 GNSS Channels

Three RF channels enable spatial signal analysis for intentional coherent spoofing detection

RF Signal Analyzer

60 MHz real-time RF signal analyzer for spectrum monitoring, interference classification and localization with TDOA.

PPS Offset Measurement

PPS input for checking time server health and monitoring the entire synchronization system. The GP-Probe measures the time offset between internal and external PPS.

24/7/365

With a dual-power module, real-time operating system, and secure firmware auto-update engine, GP-Probe protects critical infrastructure 24/7/365 days a year.

Embedded Lua Scripting

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

GP-Blocker

Optional threat blocker with an embedded GNSS jammer can suppress the most powerful counterfeit RF signals… Learn more
