KITSAT-1
KITSAT-1 or KITSAT-A (Korean Institute of Technology Satellite) is the first South Korean satellite to be launched. Once launched, the satellite was given the nickname "Our Star" (우리별). KITSAT-1 operated in a 818 miles (1,316 km) by 825 miles (1,328 km) low Earth orbit (LEO). Of the 12 satellites launched by South Korea, KITSAT-1 is in the highest orbit. While KITSAT-1 maintains equilibrium by gravity gradient forces, magnetic torque can be used to control attitude if needed. The forecasted lifespan of KITSAT-1 was only five years, but communication with the satellite was maintained for 12 years. Since the launch of KITSAT-1, South Korea launched an additional 36 satellites by 2020.
