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.
Microsemi provides a portfolio of technologies, products, and services that enables operators of Critical Infrastructure to construct a secure and robust PNT network that is resilient to GPS errors as well as errors coming from other sky-based delivery channels such as Galileo, GLONASS, BeiDou, or another. Details of this complete portfolio can be found here.
The new BlueSkyTM GNSS Firewall protects already deployed GPS systems by providing a cost-effective overlay solution installed between existing GNSS 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.
