Most affected areas

Place	Share affected	Aircraft affected
Seoul 37.8°N 127.0°E	14.3%	1 of 7
Korean Peninsula 36.7°N 127.5°E	10.2%	13 of 128

With few aircraft, one report can give a hexagon a high share; see the limitations.

Today in numbers

268 of 5,747 aircraft observations (4.7%) reported low accuracy. An aircraft counts once in each hexagon it crossed.

Hexagons by level, latest update
Level	Share of aircraft affected	Hexagons
High	over 10%	2
Medium	3–10%	15
Low	under 3%	15

By altitude

All altitudes: points to a powerful, wide-area source. How this is read.

Aircraft observations by barometric altitude, latest update
Altitude	Aircraft	Share affected
Below 5,000 ft	454	9.9%
5,000 to 15,000 ft	1,501	6.7%
15,000 to 30,000 ft	3,417	4.2%
Above 30,000 ft	2,278	2.3%

An aircraft is counted in each layer it crosses, so the rows do not add up.

Area covered

This page counts only the hexagons whose centre lies inside South Korea's borders, so hexagons in neighbouring countries and out at sea are left out. The map is framed on 33°N to 38.7°N and 124.5°E to 130°E.

Background

For the reporting on interference in this area, and who it is attributed to, see the East Asian seas.

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.
