The test was conducted at the Sohae Satellite Launching Ground on Sunday mainly to "evaluate the capabilities of satellite photography and data transmission system and ground control system," according to the Korean Central News Agency (KCNA).
The country fired a vehicle carrying a "test-piece satellite" at a lofted angle to an altitude of 500 kilometers, an unnamed spokesperson at the National Aerospace Development Administration said in a statement carried by the KCNA.
North Korea will "finish the preparations for the first military reconnaissance satellite by April, 2023," the official said, adding the results of the test were immediately reported to the central military committee of the ruling Workers' Party of Korea.
