Microsemi, a wholly owned subsidiary of Microchip Technology Inc., has introduced a global navigation satellite system (GNSS) designed to harden the security of critical infrastructure operations from GPS threats and deliver more reliable and secure service.
GPS, while beneficial in providing accurate navigation and timing, has caused critical infrastructure to be dependent upon satellite-based systems. The signals transmitted from GPS and other GNSS constellations can be a threat if disrupted, harming key infrastructure sectors such as telecommunications, energy, transportation, emergency services and data centers. These cybersecurity threats have been on the increase lately, leading to providers looking to find more, better ways to make infrastructure more reliable and secure.
The BlueSky GNSS Firewall provides protection against GPS threats such as jamming, spoofing and complete outage. The firewall supports a range of precision timing technologies, including atomic clocks, to enable continuous operation when GPS may be completely denied for extended periods.
Inside the 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, enabling continuous output of the GPS signal to the downstream GPS receiver in case of complete loss of live sky GPS reception.
