GNSS derived positioning, navigation and timing (PNT) services are used in every part of our daily lives. We use them to get from A to B, to aid the delivery of electricity to power our homes and businesses, they are used to synchronise our banking transactions and deliver many services to our ports, ships and planes - all of which are vital to our economy.

Spectrum interference is a growing problem to services deriving positioning, navigation or timing from Global Navigation Satellite System (GNSS) constellations. Interference can occur from many sources including radiation emitted from our sun in the form of space weather or from terrestrial sources such as illegal jammers.

As alternative sources of PNT to GNSS are developed, it is important to monitor and protect the GNSS Spectrum. To this aim, and to support UK PNT strategy, CGI is developing a GNSS Event Notification Service (GENS) for the UK in partnership with the European Space Agency and UK Space Agency.

GENS will integrate our PNT Incident Event Monitoring (PNTIEM) System with existing UK developed sensors from GMV NSL including DETECTOR, GISMO and Strike 3 interface technologies as well as the Ordnance Survey’s (OS) OS NET network of GNSS Receivers. Integration with OS NET provides a monitoring capability across Great Britain.

If you use high value or safety critical PNT services from GNSS in the UK or internationally and are interested in understanding GNSS Spectrum interference focused on your use cases please get in touch.
