Satrec Initiative manufactures Earth observation satellite systems carrying optical payloads, ranging from 50 to 700 kg in mass and from 0.3 to 10 m in resolution for 30 years. Satrec Initiative has been participating every domestic satellite program in Korea and also exporting satellite systems, optical payloads or satellite platform to many overseas countries. Considering electro-optical payloads for Earth observation are used only during daylight period, dual-use application for QKD has been investigated. Needs of high resolution Earth observation require bigger aperture in space may reduce the size of optical ground terminal for QKD so as to ease its deployment for commercial applications.
