PRODUCT OVERVIEW

The Microchip's BlueSky GNSS Firewall solves the problem of protecting already deployed systems by providing a cost-effective overlay solution installed between existing GPS antennas and GPS systems. Similar to a network firewall, the BlueSky GNSS Firewall protects systems inside the firewall from untrusted sky-based signals outside the firewall. Contained within the BlueSky GNSS Firewall is a software engine that analyzes the GPS signal. GPS signal data is received and evaluated from each satellite to ensure compliance with GPS standards along with analyzing received signal characteristics. This information is used by the firewall to block anomalous GPS signals and provide a hardened GPS signal output to downstream GPS systems. The BlueSky GNSS Firewall also supports a range of atomic clock technologies enabling continuous operation where GPS may be completely denied for extended periods of time, even in cases where disruptions may last for more than 30 days. 


Features

  • Identifies and protects GNSS systems from spoofing and jamming

  • Integrates seamlessly between existing GNSS antenna and GNSS system
