GNSS Radio Probe for Time & Frequency Reference System Protection
Key Features

Key Features

  • Three RF channels to detect intentional, synchronous GNSS spoofing.
  • GNSS signal quality measurements: pseudorange errors, carrier phase, SNR, etc.
  • Support: 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 guarantees high availability, reliability, and cybersecurity. The GP-Probe boots 3 seconds after power up!
  • PPS input for the external time server health checking. The GP-Probe measures the time offset between internal and external PPS. PPS input supports low-current signals.
  • Optional GP-Blocker with an embedded noise generator suppresses the most powerful counterfeit RF signals.
  • Secure firmware auto-update engine. Update the firmware of all connected GP-Probes in 40 seconds!
  • 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.
  • Double 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 (HTTP or HTTPS).
  • External devices can be controlled via remote interfaces: RS232/Telnet/SNMP 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.
