As an earth observation satellite, it will be greatly helpful to developing the nation's economy, Kim Won Guk, head of a department of Kim Il Sung University, told KCNA.

He further said:

"The satellite will serve as a foundation to drastically raise the accuracy of weather forecast.

To ensure accuracy of weather forecast, there should be correct information beforehand. The satellite makes it possible for the DPRK to gain information on temperatures of sea and land surfaces and atmosphere, humidity and wind and other meteorological data. Such information will help prevent or reduce natural disasters."

Son Tong Hyok, a teacher of the university, said:

"The second version of Kwangmyongsong-3 is an earth observation satellite urgently needed for survey of natural resources in the country.

This satellite going along the sun-synchronous orbit will be of great help to map making, agricultural development and surveys of forests, seas, geology and natural disasters."
