Satellite payload can be classified as electro-optical payload, SAR, microwave radiometer, communication payload, navigation payload and so on in accordance with the mission objective. The technology of satellite payload was tried to be obtained through development of KOMPSAT series, COMS and STSAT in Korea. In this paper, the required technology for the development and world market trend of satellite payload were studied and described. Since KOMPSAT program has been started in 1994, technology status and future prospects of satellite payload in Korea are studied and analyzed.

MSC(Multi-Spectral Camera) which is a unique payload for KOMPSAT-2, comprises main three subsystems of PMU(Paylaod Management Unit), EOS(Electro -Optical Subsystem) and PDTS(Payload Data Transmission Subsystem). The PMU, as a main controller of MSC, performs major tasks such as interfacing with S/C(Space Craft), controlling the MSC operation, distributing and controlling of operating power to all MSC including thermal unit, etc. In this paper the H/W configurations as well as the functions of PMU are introduced and possible changes for the future development are suggested.
