Sohae Satellite Launching Station, also known as Tongch'ang-dong Space Launch Center and Pongdong-ri, is a rocket launching site in Cholsan County, North Pyongan Province, North Korea.
The entire facility occupies over six square kilometers, and consists of a launch site, a static rocket motor test stand, vehicle checkout and processing buildings, a launch control building, a large support area, a complex headquarters building and an entry control point. The site is five times larger than Tonghae Launch Site.
The launch area consists of a 40 metres (130 ft) tall umbilical tower adjacent to rail served movable launch pad measuring 10 by 13 metres (33 by 43 ft). The launch pad sits towards the western end of a large concrete area in which a pair of rails is laid. When a rocket is on the pad it would be sitting next to the tower on the north side. A blast deflector can be seen on the western side of the pad. This takes turns the exhaust gases from a rocket launch through 90 degrees and funnels them out horizontally on to the nearby hillside.
