Israel is experiencing unexplained GPS disruptions in its airspace but measures are in place to allow safe landings and takeoffs at its main international airport, the government said on Wednesday.
The announcement by the Israel Airports Authority (IAA) followed a report on Tuesday by the International Federation of Air Line Pilots' Associations (IFALPA) that "many" pilots had lost satellite signals from the Global Positioning System around Tel Aviv's Ben Gurion Airport.
Confirming there had been GPS disruptions for approximately the past three weeks, an IAA statement said these affected only airborne crews and not terrestrial navigation systems.
Israeli authorities had worked from the outset to locate the source of the problem and fix it, it added.
Asked if an explanation for the disruption had been found, an IAA spokesman said: "No. I don't know."
