The BlueSky GNSS Firewall from Microchip is renowned for its robust protection against spoofing and jamming, ensuring the integrity and reliability of satellite-based timing for critical infrastructure.

The BlueSky GNSS Firewall protects deployed GNSS systems is installed between existing GNSS antennas and GNSS systems. It protects systems inside the firewall from untrusted sky-based signals outside the firewall. 

With the addition of SkyWire technology, this system provides nanosecond-level precision time measurement and verification between clocks at dispersed geographical locations to improve timing resilience.
