Track multiple GNSS Constellations for Peace-of-Mind

Multi-GNSS constellation technology has become a standard capability for most GNSS receivers. In an uncertain world of GNSS jamming, spoofing, and geo-political unrest, the ability to track multiple GNSS constellations can provide one more bit of operational peace-of-mind. While there are no guarantees, multi-GNSS tracking is a way of reducing the risk of depending entirely on one GNSS constellation alone.

GPS, GLONASS and BeiDou are GNSS constellations which are all globally available, but which are ultimately owned and operated by the military of a single country. Galileo is the only global GNSS constellation focused on civilian infrastructure.

When evaluating global usage of GNSS by critical Infrastructure providers, too many have become overly dependent on GPS because of its ubiquitous availability and long-standing reliability. Now that Galileo has become equally ubiquitous, the combination of GPS and Galileo provides for redundancy and diversification such that GPS is not a single point of failure.

However, like GPS, the signal reception of Galileo is vulnerable to the same threats of jamming and spoofing, whether intentional or unintentional. Protection of live-sky GNSS reception using a well proven “firewall” architecture provides for a secure and resilient use of both GPS and Galileo.

The BlueSky GNSS Firewall with its extensible platform and upgrade capability, delivers future proof security to defend against new threats for continued security of GPS and Galileo reception.
