GP-PROBE TGE2

Three-channel probe for GNSS signal quality measurements and GNSS threat detection

The GP-Probe TGE2 is designed to protect time servers (PNT) against a GNSS threat such as cutting-edge intentional spoofing, jamming, ionospheric scintillation and system errors. An embedded PPS phase error measurement function enables the reliable monitoring of the time server’s health. The GP-Probe can also be used in conjunction with the GP-Cloud to develop 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:

  • GNSS signal quality measurements: pseudorange 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.

  • 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. The GP- Divider supports the GNSS antenna preamplifier current simulation.

  • 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.

Key Benefits

Spatial Signal Analysis

Three RF Channels enable spatial signal analysis to ensure detection of all sophisticated GNSS spoofing attack scenarios

Guaranteed High Availability And Cybersecurity

The embedded real-time operating system FreeRTOS guarantees high availability and cybersecurity.

PPS Offset Measurement

PPS Offset Measurement for checking time server health and monitoring the entire synchronization system. The GP-Probe measures the time offset between internal and external PPS. PPS input supports low-voltage signals.

Real-Time Signal Analyzer

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

Remote Control

External devices can be controlled via remote interfaces: RS-232/RS-485/RS-422 with embedded Lua scripting language. GP-Probe can send commands to the connected time server for switching to holdover, etc. This facilitates integration with existing client infrastructure.

Auto-Update

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