Description:

• The goal of the KOMPSat 5 (Korean Multi-purpose Satellite 5) project is to lead the development of the first Korean SAR Satellite using manpower and facilities from the KOMPSAT-3 program. It aims to support the national SAR (Synthetic Aperture Radar) satellite demand and form a technology infrastructure to make inroads into the world space industry.
• Its payload will be an X-band SAR and it will operate at Dawn-Dusk orbit between an altitude of 500 km to 600 km.
• It will execute all weather and all day observations of the Korean peninsula during its five year mission using the SAR payload, unlike KOMPSAT- 1, -2 and -3. The nation's urgent demand for SAR image information, which is different from optical image information obtained by optical remote sensing satellites, will be fulfilled by the KOMPSAT-5. And in order to meet the urgent national needs for various SAR image information, the KOMPSAT-5 GOLDEN Mission will provide GIS (Geographical Information Systems), Ocean monitoring, Land management, Disaster monitoring, and Environment monitoring.
• The primary mission of the KOMPSAT-5 system is to provide high resolution mode SAR images of 1 meter resolution, standard mode SAR images of 3 meter resolution and wide swath mode SAR images of 20 meter resolution with viewing conditions of the incidence angle of 45 degrees using the COSI (COrea SAR Instrument) payload, for meeting GOLDEN mission objectives
• The secondary mission of KOMPSAT-5 is to generate the atmospheric sounding profile and support radio occultation science using AOPOD (atmospheric occultation and precision orbit determination) secondary payload which is composed of a dual frequency GPS receiver and a laser retroreflector array (LRRA).

Mission details:

• Launch delayed from January 2012.
• South Korea's KARI agency has launched its first X-band SAR satellite, the `No. 5 Multi-Purpose Satellite' (damogjeogsil-yong-wiseong 5-ho, KOMPSAT-5).
  The KOMPSAT-5 satellite (also known as Arirang-5) was launched from the Russian missile base at Yasniy/Dombarovskiy on Aug 22, 2013 aboard a Dnepr rocket (recycled R-36M missile). The satellite is in a 553 x 552 km x 97.6 deg sun-synchronous orbit with a 17:59LT descending node; it has a mass of about 1400 kg.
