Abstract

This paper proposes appropriate locations for site diversity to provide stable satellite communication service in Korea. For this purpose, we analyzed rainfall rate data measured by KMA for 5 years at 88 sites, and the variations of simultaneous occurrence of rainfall rate in pairs of sites using the correlation coefficient. This paper provided contour maps of the spatial ditstribution of rainfall rate correlation, and proposed information on the optimum sites/regions for the operation of muti-uplink satellite systems, in 4 cities which were principal in field of satellite communication in Korea.

본 논문에서는 한반도 지역 내에서 안정적인 위성통신 서비스를 위한 최적의 망 이중화 지점을 제안한다. 이를 위해 기상청에서 측정한 88개 지점, 5년간의 강우량 데이터를 분석하였으며, 상관관계를 이용하여 두 지점간 강우가 동시에 발생할 확률 변화를 분석하였다. 국내 위성통신 관련 4개 주요 지점을 중심으로 강우 발생 상관도 변화를 등고선 맵으로 분석하였으며, 송신 지구국 이중화 지점으로 가장 적합한 지점/지역에 대한 정보를 제안하였다.
