Dr Yossi Golobchiev from JCT's Electronics department discusses the recent scrambling of Israel's GPS systems, and how it relates to security

Translated from original article in Hebrew from Channel 7

Recent disruptions to GPS services in central Israel are being seen as defensive measures against a possible missile attack from Iran. Dr. Yossi Golobchiev, from the Jerusalem College of Technology, sheds light on how missile targeting systems are linked to GPS navigation.

Notices of GPS interference in Israel’s central region have emerged, linked to defenses against a potential Iranian missile assault. We engaged with Dr. Yossi Golobchiev, a specialist at Jerusalem College of Technology, for insights on the interplay between GPS navigation and missile guidance systems.

Dr. Golobchiev outlines that missile guidance often relies on GPS signals. Jamming these signals can thwart a missile’s path. “By disrupting GPS signals, you hinder a missile’s guidance system, affecting its trajectory,” he explains.

He further highlights the challenge in distinguishing between military and civilian GPS use. “The ubiquity of GPS technology means it’s as accessible to civilians as it is to potential threats,” Dr. Golobchiev remarks, noting the expanded use of frequency jammers and their intensity as a precaution against widespread attacks. Golobchiev notes that "the defense systems have additional infrastructure systems. There is satellite communication for military purposes and there are radar systems.”

On legal and technical fronts, Golobchiev emphasizes that frequency jamming is prohibited to civilians, underscoring the complexities of deploying such measures without affecting civilian infrastructure.

When asked about the broader impact of GPS jamming, Dr. Golobchiev acknowledges potential disruptions across various sectors, including aviation and military communications. He remains optimistic, however, about a return to normalcy once security risks subside.

In anticipation of a future with autonomous vehicles reliant on GPS, Dr. Golobchiev stresses the importance of developing resilient emergency backup systems to safeguard against navigation disruptions.
