The South Korean CAS500-1 and CAS500-2 (Compact Advanced Satellite 500) space vehicles are Earth-observation models that will image the Earth in panchromatic and multispectral modes using the AEISS-C (Advanced Earth Imaging Sensor System) payload.

The CAS500 satellites will feature the AEISS-C (Advanced Earth Imaging Sensor System) imaging system with a ground resolution of 0.5 m in panchromatic mode and 2 m in color mode.

The satellites will be launched 2020 on two Soyuz-2-1a Fregat rockets from Baikonur.

The second satellite was to be launched in 2022 also on a Russian Soyuz-2-1a Fregat rocket. Due to sactions because of the Russian invasion of Ukraine, the launch on a Russian launch vehicle was cancelled.
