Review of SMOS Mission and Current Operation

SMOS 위성 개발 및 운용 현황

  • Published : 2010.02.28

Abstract

The second satellite in ESA's Earth Explorer series, the Soil Moisture and Ocean Salinity (SMOS) mission was launched into orbit at November 1, 2009. The SMOS will play a key role in the monitoring of climate change on a global scale using the payload of L-band synthetic aperture radiometer. It is the first ever satellite designed both to map sea surface salinity and to monitor soil moisture on a global scale, and will provide the important data to study the water cycle among oceans, the atmosphere and land. To introduce the operation of the SMOS, this paper shows brief summary of appearance and current operation.

유럽 우주국 (ESA)에서 지구 탐사 계획의 일환으로 개발한 두 번째 위성인 SMOS (Soil Moisture and Ocean Salinity) 위성이 지난 2009년 11월 발사되어 궤도에 안착, 운행 중에 있다. SMOS는 탑재된 L 대역 합성 개구형 라디오미터를 이용하여 상시 전지구적으로 토양 수분량과 해양 염도를 측정하는 것을 목표로 한다. 이를 통하여 지구의 물순환 및 기상, 기후 연구에 주요한 데이터를 얻을 수 있다. 본 글은 SMOS 발사와 관련된 개괄적인 연구 개발과 현재 운용 현황에 대해 설명한다.
