    Recently, the development and launch of microsatellites is increasing. However, launch costs are decreasing due to reusable launch vehicles and satellites co-launches. In particular, the number of satellites is increasing exponentially due to LEO communication services using mega cluster satellites. As a result, space debris is increasing exponentially. In addition, satellite operators sometimes miss the timing of satellite disposal by maximizing operation at the end of life of a satellite in order to pursue maximum profits. In order to escape from the threat of space debris, the satellite deorbit systems into the earth’s atmosphere and space debris cleaning satellites are being developed in many countries. In this paper, we will analyze the overseas trends of various deorbit systems and review the possibility of domestic satellite application in the future.
