Report from the working group on GNSS/GPS-disruptions in aviation

GNSS (Global Navigation Satellite Systems) is a collective term for satellite systems in outer space that have a broad area of application, including in association with critical infrastructure. At worst, uncontrolled outage of such infrastructure can have disastrous consequences. Services provided by these systems include access to low-cost and accurate position, navigation and timing data. The US Global Positioning System (GPS) and the European Galileo system are examples of individual systems that are especially relevant in Norway. Over a prolonged period in 2018, Norwegian aviation experienced GPS signal jamming from the Russian side of the border. Northern Norway was especially exposed, including during the NATO exercise Trident Juncture in the autumn of 2018. In light of the consequences for aviation, Norway raised the matter with Russia on a number of occasions, but this failed to change the situation. The phenomenon could thus not be assumed to be of a passing nature.
