  "account": "A Norwegian rescue helicopter and a small plane conducted maneuvers over the Andøya training ground in 2024, but their satellite navigation screens displayed false routes. Neither display matched the aircraft's true path. The deceptive tracks were part of a yearly exercise, called Jammertest, designed to test how equipment reacts when satellite signals are interfered with or falsified. This event, held on Andøya island near the Arctic Circle, gathers engineers, public agencies, and companies reliant on Global Navigation Satellite Systems, or GNSS. As interference around Russia's conflict in Ukraine escalates, the exercise has gained importance. In May 2025, an RAF aircraft faced GPS jamming near the Russian border. In September 2025, Sweden's Transport Agency reported daily interference issues. In June 2026, Russian satellites transmitted interference that briefly disrupted GPS signals across Europe. Aviation, where effects are immediately apparent, serves as a clear example of the problem. However, GNSS interference can also impact other sectors like communications, power grids, transport systems, and financial markets, which depend on precise timing. Jammertest simulates the risk of spoofing, a slower-threat where a stronger counterfeit signal gradually replaces the valid one, manipulating position and time. The Norwegian Metrology Service's Harald Hauglin and his team demonstrated this in 2024 by increasing the spoofing signal's strength over 40 minutes. As the fake signal grew stronger, a map display shifted the test site's reported location into the Norwegian Sea. While detecting the positional error was straightforward, measuring the time shift required a different setup. They compared a GNSS-synchronized clock with a reference clock connected by fiber-optic cable to a receiver outside the test area. The difference between the two was measured in nanoseconds, highlighting how a manipulated signal can slowly move a clock away from the correct time. This issue is critical for systems requiring a common clock to function, such as power grids or mobile networks. While local clocks, atomic references, and fiber-optic links can maintain precise timing, they increase costs. The more concerning scenario is a slow-moving spoofing attack that goes unnoticed, continuing to feed the system false data. Over time, this could cause synchronization problems across connected networks. Jammertest aims to identify such weaknesses before they occur in real disruptions. Participants test commercial and industrial receivers in an open setting and share results with other attendees. Norway and other governments are exploring options like fiber-based timing networks and atomic clocks to mitigate the increasing threat of GNSS interference. However, there is no single solution, and experts suggest a combination of systems as the best approach.",
