Operation of the Radio Occultation Mission in KOMPSAT-5

Abstract

Korea multi-purpose satellite-5 (KOMPSAT-5) is a low earth orbit (LEO) satellite scheduled to be launched in 2010. To satisfy the precision orbit determination (POD) requirement for a high resolution synthetic aperture radar image of KOMPSAT-5, KOMPSAT-5 has atmosphere occultation POD (AOPOD) system which consists of a space-borne dual frequency global positioning system (GPS) receiver and a laser retro reflector array. A space-borne dual frequency GPS receiver on a LEO satellite provides position data for the POD and radio occultation data for scientific applications. This paper describes an overview of AOPOD system and operation concepts of the radio occultation mission in KOMPSAT-5. We showed AOPOD system satisfies the requirements of KOMPSAT-5 in performance and stability.

“…We further include data from the South Korean Kompsat-5 satellite. This mission was launched in August 2013 with the main focus on acquiring independent high-resolution SAR (synthetic aperture radar) images (Choi et al 2010;Lee et al 2020). Additionally, the satellite has provided approximately 400 RO profiles per day since July 2019.…”
