In order to provide nanosecond-accurate UTC timing for critical infrastructure such as 5G networks, transportation, data centers, smart grids, high-frequency trading, military and first responder communications, and satellite terminals, Viavi Solutions launched its altGNSS GEO SecureTime services.
VIAVI’s altGNSS GEO service, which runs entirely independently of conventional GPS and GNSS and has the widest worldwide coverage in the industry, is incredibly hard to jam or spoof, further strengthening its defense against more frequent assaults.
SecureTime expands the industry’s most comprehensive range of reliable PNT solutions with the use of Navigation Message Authentication (NMA), which uses encryption to detect signal spoofing in any of the signals received from any source, even GPS that does not support NMA.
It builds upon VIAVI’s present multisource assurance by combining signals from commercial and government constellations in Geosynchronous Orbit (GEO), Low Earth Orbit (LEO), and Medium Earth Orbit (MEO).
These services have been tried and proven in actual combat scenarios. For example, in a warzone simulation, they successfully supplied assured PNT while completely denying GPS and GNSS capabilities.
VIAVI will include these services into its own products in addition to providing receivers to other solution providers who wish to use the altGNSS services in their own systems.
VIAVI’s SecurePNT 6200 hardware architecture is powered by TrustedPNT multisource fusion technology and space and terrestrial SecureTime Services.
VIAVI is scheduled to present these solutions at two upcoming conferences: the Assured PNT Summit (May 29–30 in Washington, D.C.) and the Joint Navigation Conference (June 3-6 in the Greater Cincinnati, Ohio region).
“Critical infrastructure around the globe is increasingly susceptible to PNT disruption, but that is even more apparent in theaters of war,” said Doug Russell, Senior Vice President, AvComm, VIAVI. “Our SecureTime services have steadily built up an unsurpassed capability to protect timing in critical networks, independent of any one source or frequency band.”
