Where GPS in Israel goes dark or starts lying, in real time. We show where, not who.
Showing data as of How it works / MethodologyThousands of ground vehicles are moving across Israel at any given moment. When enough of their GPS receivers suddenly go dark, or insist they just landed in Amman, we see it. The map turns that noise into one clear picture: where GPS works, and where it breaks, in real time.
All of Israel is covered in hexes. Green is the default, meaning the area is calm; as interference grows, the color shifts from yellow to orange to red. We show where it happened, not who caused it, not how, and not in which vehicle, with a short delay of a few minutes to protect privacy.
Jamming floods GPS signals with noise until the receiver simply loses its position. It doesn't get the location wrong; it has no idea where it is at all.
Spoofing is sneakier: a fake GPS signal convinces the receiver it's somewhere else entirely. It doesn't lose its position; it is 'certain' it's in Amman while it's actually in Haifa.
Thousands of ground vehicles broadcast GPS positions all day. When enough of them report the same anomaly in the same area, a sudden dropout or an impossible position jump, we aggregate it into a geographic cell and color it by intensity. One vehicle is noise; a whole area is an event.
Every few minutes. There's a short delay between what happened in the field and what shows up here, and that's deliberate: it means no single vehicle can be tracked in real time.
Privacy. The delay and aggregation guarantee that no one can take this map and reconstruct a specific vehicle's route. We show the phenomenon, not the source.
Clear = no interference detected. Weak = a faint anomaly we detected, possibly incidental. Moderate = clear, consistent interference confirmed by several vehicles. Heavy = strong, widespread interference. These are intensity bands, not exact numbers.
Green means 'we didn't detect interference here,' not 'guaranteed none.' Each hex is as good as the number of vehicles that passed through it: sharp in busy areas, fuzzier in remote ones. Treat it like a weather forecast, not an atomic clock.
No, and that's by design. We show where GPS broke down and how badly, without attributing it to a perpetrator, device, technology, or intent.
No. Everything is aggregated into geographic cells only: no precise location, no license plate, no vehicle identifier, and no vehicle count. Just an intensity band per area.
We filter the usual suspects: tunnels, underground parking, narrow streets between tall buildings, and parked vehicles. But no map is perfect: an area with interference might not have gathered enough data, or a cell might light up from a random anomaly. A forecast, not a prophecy.
Maps like GPSJam and Flightradar24 rely on aircraft with ADS-B receivers: broad coverage, but high above the ground. We rely on vehicles driving on the road, so we're sensitive to interference exactly where people live, drive, and work.
