Today in numbers
278 of 37,361 aircraft observations (0.7%) reported low accuracy. An aircraft counts once in each hexagon it crossed.
| Level | Share of aircraft affected | Hexagons |
|---|---|---|
| High | over 10% | 0 |
| Medium | 3–10% | 7 |
| Low | under 3% | 176 |
By altitude
Mostly low altitude: points to local, low-power jammers. How this is read.
| Altitude | Aircraft | Share affected |
|---|---|---|
| Below 5,000 ft | 6,089 | 2.4% |
| 5,000 to 15,000 ft | 11,238 | 0.4% |
| 15,000 to 30,000 ft | 13,610 | 0.0% |
| Above 30,000 ft | 17,789 | 0.0% |
Area covered
This page counts only the hexagons whose centre lies inside the United Kingdom's borders, so hexagons in neighbouring countries and out at sea are left out. The map is framed on 49.8°N to 60.9°N and 8.7°W to 1.8°E.
Background
In the United Kingdom, operating a jammer is an offence under section 68 of the Wireless Telegraphy Act 2006, and the Ministry of Defence runs occasional authorised tests that can cause some loss of service (Ofcom). Interference seen only at low altitude points to a local, low-power jammer; see how the altitude layers are read. For the wider region, see the Baltic Sea.
About these figures. Low reported accuracy points to interference but does not prove it, and the map cannot locate a transmitter or say who is responsible. How the map is made.
