Blog Editor’s Note – We posted a couple items last week about the world’s biggest jammer test recently held in Norway – JammerTest 2022.
It turns out the folks at GPS Patron participated in the the week-long event. GPS Patron have always had an active communications program, especially when it comes to their findings about jamming and spoofing. They have fully documented their JammerTest 2022 experience on their website, including with two videos.
They are also eager to share all the data they recorded with anyone. Just go to the end of the post on their site and let them know you are interested.
Several interesting tidbits to whet your appetite:
- As soon as the Norwegian authorities turned on their equipment the first day, they detected unauthorized jamming from somewhere.
- Some kinds of “jamming” caused some receivers to still report positions, but tens of kilometers from the correct location.
- Even if you are a good guy, it is important to secure your gear properly. Else you could end up spoofing when you didn’t mean to!
Intro
From 19 to 23 September 2022, the Norwegian Public Roads Administration, the National Communications Authority, and the Norwegian Defense Research Institute hosted “JammerTest2022” in northern Norway. In our opinion, this is the biggest civilian GNSS jamming/spoofing testing we know about and where we participated.
Over five days, a wide range of GNSS interference was generated to test GNSS equipment resilience. From basic L1 jamming to sophisticated spoofing scenarios.
GPSPATRON’s team has recorded all the interference in the GP-Cloud database and is making it open to the community!
