Abstract:
The NSOS-beta (Near Space Optical Survey-beta) is designed as an optical space surveillance system to monitor space objects in the Medium Earth Orbit and Geostationary Earth Orbit (GEO) region near the Korean Peninsula. The primary objective of NSOS-beta is not only to monitor satellites in GEO and inclined GEO owned by South Korea but also to independently track approaching space objects that could potentially collide with them. To achieve this, it will survey the high-orbit region containing South Korean GEO and inclined GEO satellites to detect space objects and acquire orbit information for specific target space objects. The survey of space object will primarily utilize a 0.8-meter diameter main telescope, with a 0.4-meter diameter auxiliary telescope equipped with CMOS to focus on monitoring South Korean GEO satellites. This effort will lead to the cataloging and management of detected space objects in the high-earth orbit region near South Korea, including obtaining orbit information for South Korean GEO satellites and potentially colliding space objects. The development of NSOS-beta is expected to span approximately four years, with two systems planned for installation in the Southern Hemisphere.
