다양한 지상국에 따른 달 탐사선-지상국 Ka 대역 햐항링크 성능 분석

초록

For high data-rate transmission of large multimedia data, it is necessary to utilize space communication technologies in Ka-band and secure sustainable communication paths. In this paper, the down-link performance is analysed in Ka-band between a lunar orbiter and an earth station of various configurations. First, a link model between a lunar orbiter and an earth station is constructed based on CCSDS and NASA DSN standards. Then the down-link performance for data-rates and rain-rates is drawn for various configurations of the earth station. The results of link performance analysis in this paper can be used in designing reliable space communication systems in the future.
