DS-SAR is a Singaporean SAR Earth Observation satellite. It is built by IAI.

The satellite will be used for government and commercial purposes; DS-SAR will be used to support the satellite imagery requirements of Singapore government agencies, including for maritime security and the detection of oil spills. At the same time, the images captured by DS-SAR will be used to enhance ST Electronics’ commercial imagery services.

DSTA (Defence Science and Technology Agency) – part of the Singapore Ministry of Defence – alongside ST Electronics – part of major regional defence and engineering group ST Engineering – have ordered in 2018 an Synthetic Aperture Radar (SAR) satellite from Israeli manufacturer Israel Aerosapce Industries (IAI). This foreign-built SAR, DS-SAR, satellite will support their already in orbit, domestically built TELEOS 1 Earth observation spacecraft which was launched in 2015.
