This also caused missed approaches, produced a large map shift on the navigation display, and affected TAWS terrain indications.īennington said the “Pokemon Go” augmented reality app released in 2016 encouraged hackers to spoof GPS to win prizes and put code online. In second-quarter 2016, there were more than 50 reports of GPS interference on approach to Runway 24 at Manila International Airport, producing a loss of onboard GNSS functionality and GPS-L and GPS-R invalid messages, as well as a decrease in navigation performance leading to an RNP alert. Last year, GPS was jammed by Russia for one week in Norway. This includes the Eastern Mediterranean Sea earlier this year, where five sea vessels and one aircraft had interference over extended periods of time, with some vessels up to 25 miles off course.
But we know it was far more than that because in the reported cases they busted some sort of regulatory requirement they busted altitude or went to the wrong place.”īennington noted several examples of GPS jamming/interference in recent years. “Since 2013 the FAA Aviation Safety Information Analysis and Sharing System has recorded more than 100 instances of pilot reports of GPS systems being jammed. He added that the risk to aviation safety is real and tangible. Yes, it is illegal, but if you are jamming GNSS you probably don't care,” said Jeremy Bennington, Spirent corporate solutions and technical strategy lead. You can go out and get a piece of jamming equipment rather easily. “Global navigation satellite system jamming essentially is as hard as it is to get your credit card out.
During the last three years, Spirent Communications, a company that tests navigation equipment, has captured 150,000 different jamming and interference events.
GPS jamming and interference events are growing exponentially as aircraft systems are becoming increasingly reliant upon them for primary navigation.
