Three days after North Korea released a picture of downtown Seoul, which is believed to have been taken from a reconnaissance satellite test product, a picture of the Kim Il-sung Square in Pyongyang taken from South Korea's 'National Satellite No. 1' was released.
The Ministry of Land, Infrastructure and Transport announced that it will open a satellite photo exhibition taken by 'National Land Satellite No. 1' at the Land Development Exhibition Center in Jung-gu, Seoul from tomorrow (23rd).
The Ministry of Land, Infrastructure and Transport released satellite photos of the Kim Il-sung Square area.
The photos released by the government clearly captured the appearance of the Kim Il-sung Square area, creating a sharp contrast with the blurry black-and-white photos of the North Korean side.
The difference in satellite technology level between the two Koreas is clearly revealed with just one photo.
In the photos taken by 'National Satellite No. 1', the shape of buildings around Kim Il-sung Square, including the People's Study House, the Joseon Central History Museum, and the Joseon Art Museum, in Pyongyang were clearly captured.

On the other hand, experts say that the photos released by North Korea on the 19th are poor enough to be taken by a military reconnaissance satellite.
In the black and white satellite photos released by North Korea, it is possible to identify large-scale facilities such as the Han River Bridge and Incheon Port, but only the outline of the Yongsan Presidential Office and Samgakji area must be enlarged to blur.
The 500kg-class next-generation medium-sized satellite 'Kuksat-1' is equipped with an optical camera with a resolution of 0.5m in black and white and 2m in color.
The government launched the satellite in March last year from Kazakhstan.
In other words, the picture taken from our land management satellite showed a resolution closer to that of the reconnaissance satellite than the picture North Korea claimed to have taken from the test product of the military reconnaissance satellite.
