California, USA - 24 September 2018, Chronos's partner Microsemi Corporation, a wholly owned subsidiary of Microchip Technology Inc. (Nasdaq: MCHP), has released new BlueSky™ GNSS Firewall which enables critical infrastructure providers to harden the security of their operations from GPS threats and deliver a more reliable and secure service. The security-hardened system provides protection against GPS threats such as jamming, spoofing and complete outage. It also supports a range of precision timing technologies, including atomic clocks, to enable continuous operation when GPS may be completely denied for extended periods. In addition, Microsemi is expanding the GNSS portfolio with the introduction of a BlueSky option to its TimePictra™ software management suite, providing centralised control and visibility of GPS reception across regional, national and global geographic areas.

Microsemi launched the BlueSky GPS Firewall Evaluation Kit at last year's ION GNSS+ show to help customers understand GNSS vulnerabilities and how a firewall approach could provide protection. They received valuable feedback from customers as a result of those evaluations and have incorporated new features in the second-generation BlueSky GNSS Firewall. In addition to expanded monitoring and reporting capabilities, the platform is now equipped with atomic clock technology to provide security-hardened resiliency, including the ability to operate in a GNSS-denied environment for more than 30 days.

Microsemi has applied the same principles of a firewall used for network security to defend against GPS threats coming from the sky. Within the new BlueSky GNSS Firewall, the incoming GPS signal is analyzed in real time to detect a wide range of threats before connected GPS receivers and related systems are affected. The BlueSky GNSS Firewall incorporates an optional internal rubidium Miniature Atomic Clock (MAC) enabling continuous output of the GPS signal to the downstream GPS receiver in case of complete loss of live sky GPS reception.

The BlueSky GPS Firewall platform features optional BlueSky software incorporated into Microsemi's TimePictra management system. To ensure BlueSky is equipped to defend against an ever-evolving threat, Microsemi updates and continuously tracks GPS signal manipulation, spoofing threats, jamming attacks, multipath signal interference, atmospheric activity and many other issues which can create GPS signal anomalies, disruptions and outages. These updates are available through a BlueSky subscription service.

BlueSky GNSS Firewall is available for orders now with delivery beginning in November 2018.
