Industrial firewall BlueSky™

The vulnerability of GPS systems to various signal incidents is well documented. The rapid proliferation of GPS systems has embedded these vulnerabilities into critical national infrastructure as well as corporate infrastructures that rely on GPS-delivered position, navigation and timing (PNT) for daily operations. The widespread deployment of GPS makes it impractical to replace all fielded GPS systems in a timely or cost-effective manner. The new BlueSky GPS Firewall protects already deployed GPS systems by providing a cost-effective overlay solution installed between existing GPS antennas and GPS systems. Similar to a network firewall, the BlueSky GPS Firewall protects systems inside the firewall from untrusted sky-based signals outside the firewall. Identifies and Protects GPS Systems from Spoofing and Jamming Contained within the BlueSky GPS Firewall is a software engine that analyzes the GPS signal. GPS signal data is received and evaluated from each satellite to ensure compliance along with analyzing received signal characteristics. Integrates seamlessly between existing GPS Antenna and GPS system Microsemi’s BlueSky GPS Firewall is deployed in-line between an existing GPS antenna and GPS receiver system and can be placed near the GPS receiver system or near the point at which the GPS antenna cable enters the building. Thus, nearly all currently deployed GPS antennas are supported without modifying the existing installation.
