GPS revolutionized the world with its ability to provide an accurate, reliable, and cost-effective positioning, navigation, and timing (PNT) service with global coverage. Its rapid adoption and widespread proliferation enhances our way of life, but has also led to a dependency on GPS to maintain that way of life. Critical infrastructure sectors such as wireline and wireless networks, power grids, data centers, and emergency services now depend on PNT information delivered by GPS.
The vulnerability of GPS systems to various signal incidents is well documented. Just watch this CNN video and see for yourself. The rapid proliferation of GPS systems has embedded these vulnerabilities into critical national infrastructures as well as corporate infrastructures that rely on GPS delivered PNT for daily operations. This widespread deployment of GPS makes it impractical to replace all fielded GPS systems in a timely or cost-effective manner.
Microsemi’s BlueSkyTM GPS 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 GPS Firewall protects systems inside the firewall from untrusted sky-based signals outside the firewall.
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 with GPS standards IS-GPS-200 along with analyzing received signal characteristics. This information is used by the firewall to eliminate anomalous GPS signals and provide a hardened GPS signal output to downstream GPS systems.
Management of wide scale deployment of BlueSky GPS Firewall units is simplified using Microsemi’s TimePictra management system. TimePictra enables a regional, national, or global view of your PNT infrastructure to provide early alerting of threats before your PNT network is violated.
