“The signal that has been disrupting satellite navigation for planes flying through #Israeli airspace in recent weeks originates inside a #Russian air base inside #Syria, according to data collected by a #US-based researcher.”
“This interference to the GPS reception doesn’t appear to be specifically directed at #Israel, but rather...is likely collateral damage in an effort by Moscow both to protect its troops from #drone attacks & to assert its dominance in the field of #electronicwarfare#Russia
“Using a series of sensors onboard the International Space Station, [a #US] team [has] been tracking the phenomenon for several mos. They were able to id. the geographic source of the signal:..Khmeimim Air Base, which was built by #Russia in 2015 along Syria’s western coast...”
”“[The signal] is so strong that I can see it from space,” said Humphreys, an aerospace engineer, specializing in satellite-based navigation.”

“Similar GPS disruptions have been reported in recent years around the #BlackSea, along #Russia’s borders with Norway & Finland, & near the #Kremlin & Russian President Vladimir #Putin’s palace.”
#Israel’s Airports Authority, the interference has not caused any safety issues there are several methods that can be used for takeoffs & landings, but it has had a significant, [yet] not overly dangerous, impact on pilots’ ability to fly...planes, as...aircraft rely...on GPS.”
”“It’s a nuisance...,”
...only affects ✈️ in the air over #Israel; there is no interruption of GPS service on the ground. ...this is because the tech being used works on lines of sight. Due to the curvature of the earth 🌍, the signal can’t reach GPS receivers over the horizon.”
“This GPS denial of service does not affect #Russian pilots taking part in the civil war in #Syria, as #Russia does not rely on #GPS satellites for its navigation. Instead, Russia uses its indigenous Global Navigation Satellite System, or GLONASS.
“...the jamming appeared to be an effort by #Russia to prevent attacks by #drones that rely on #GPS navigation to attack their bases & personnel, but also is a way for #Moscow to demonstrate to the entire world its “dominance in the radio spectrum.””
