Major update to firewall software strengthens GNSS protection

25-06-2020 | Microchip Technology | Subs & Systems

Microchip Technology today announced the release of a major software update for its BlueSky GNSS Firewall product, giving a higher level of resiliency against GPS vulnerabilities for systems dependent on GPS signal reception.


The company's BlueSky GNSS Firewall Software Release 2.0 performs real-time analysis to identify jamming and spoofing for guarding reception of the GPS signal and hardening response and recovery to evade signal disruption. The software incorporates charting and advanced threshold settings of GNSS observables such as satellites-in-view, position dispersion, carrier-to-noise, phase time deviation and RF power level to simplify system turn-up and deployment.


The software includes enhancements developed by the company as a result of participation in an industry live-sky testing event hosted by the US DHS Science and Technology Directorate and open to all providers. The company's participation in the DHS-hosted GPS Testing for Critical Infrastructure events, with scenarios including spoofed signals, has assisted the company in identifying new solutions to stop signal disruptions. As a result of 2019 live-sky testing and other input, the company developed the software's Release 2.0 to address operators’ evolving demands.


The software is produced as part of a subscription service and is installed on the firewall device. When connected to the company's TimePictra management software, critical infrastructure operators also can monitor and analyse GNSS signals in cities, across geographic regions, throughout a country and even globally.
