South Korea, Japan to Plus-Up Position, Navigation and Timing Satellite Systems

摘要

LOS ANGELES - The governments of South Korea and Japan are each in the midst of building up their respective position, navigation and timing (PNT) satellite constellations to provide more accurate service to their militaries and civilian users, officials said June 11. Many countries – to include the United States, Russia and others – have built up their own PNT capabilities, and the Republic of Korea has decided it’s time to do the same, said Lt. Col. Yun Kyong Sung, who serves as the Command, Control, Communications, Computers and Information (C4I) Interoperability Officer for the ROK.
