In an incident measured at Logan Airport in Boston, Massachusetts, the airport's ground approach system recorded temporary anomalies caused by simple electronic jammers and cigarette lighters in vehicles near the airport.
With the help of these miniature GPS jammer, which cost less than $50, users can generate RF interference bubbles around the vehicle, thereby disrupting the work of tracking the vehicle with GPS signals. A quarter mile wide. Problems arise when the vehicle passes through airports or other facilities that rely on GPS positioning and time.
"The GPS signal is weak and easily interrupted," Buensel emphasized. "We have been monitoring GPS-L1 interference since May 2015. We put the receiver on the roof of the UK. I think we are lucky to see the interference. Hundreds of incidents have been recorded within a month. We were affected by interference. Surrounded by.” is a lot of electrical switchgear. There are many accidental failures, but we have seen some deliberate failures. "
Will deliberate and accidental GPS interference cause airplanes to fall from the sky or trucks to hit buildings? Buensel said this is unlikely because most GPS devices that are critical to business and life have enough backups to handle intermittent outages.
