BlueSky GPS Firewall
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 with 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.
Optional 1PPS and 10 MHz timing reference inputs for extended holdover
Optional input capability from an atomic reference (10 MHz or 1PPS input) enables users to enhance the performance of the BlueSky GPS Firewall. Adding an atomic reference enhances anomalous GPS detection capabilities while also extending holdover performance for accurate time in the absence of live-sky GPS availability.
Upgradeable Software in addition to secure and easy-to-use web interface
At the core of the BlueSky GPS Firewall is a programmable anomaly detector that validates the GPS subframes for spoofing incidents based on defined data validation rules. A wide range of rules has already been built into the BlueSky GPS Firewall to detect suspicious time and position inconsistencies. As with traditional security firewalls, new validation rules are dynamically loaded into the BlueSky GPS Firewall as new threats are identified.
Seamless integration with TimePictra
Management of wide-scale deployment of 10’s, 100’s or 1000’s of BlueSky GPS Firewall units is simplified using Microsemi’s TimePictra management system. TimePictra enables a regional, national, or a global view of your PNT infrastructure to provide early alerting of threats before your PNT network is violated.
