GP-Blocker
Safeguard Your GNSS Timing Against Spoofing Attacks
GNSS spoofing is a growing threat to any system that depends on precise timing and positioning. From telecom networks and data centers to financial trading platforms and defense infrastructure, even brief disruptions can lead to data loss, compliance failures, and costly downtime.
GP-Blocker is purpose-built to defend GNSS-dependent time servers against spoofing attacks. By automatically isolating the GNSS antenna and switching systems into secure Holdover mode, GP-Blocker preserves the accuracy of your PPS signal—even during sophisticated interference attempts.
GNSS receivers are highly sensitive by design. While this enables precise positioning and timing, it also makes them vulnerable to malicious spoofing signals. Military-grade spoofing or nearby SDR devices can overpower legitimate satellite signals, leading to:
GP-Blocker provides a robust layer of defense that prevents spoofed signals from reaching your time server.
Standard GNSS antennas can output signals up to 5 dBm, while receiver sensitivity can reach –145 dBm. Blocking spoofing attempts requires extremely high RF isolation—far beyond what typical commercial switches provide.
GP-Blocker delivers:
GNSS spoofing threats are evolving—your defenses should too. GP-Blocker ensures your timing systems remain accurate, secure, and resilient under even the most challenging conditions.
