Technical Session VI: The Year Ahead

Abstract

The Satellite Technology Research Center (SaTReC) has successfully developed and operated three micro satellites, KITSAT-1, 2, and 3 in the last decade and have developed the flight model of KAISTSAT-4 (STSAT-1) planned for launching in September, 2003. As a successor of the series, the SaTReC is designing the next small satellite STSAT-2 (Science & Technology Satellite-2) which will be launched into a highly eccentric ellipsoidal orbit by the first Korean launch vehicle called KSLV-I (Korean Satellite Launch Vehicle -I) in the end of 2005. The mission objectives of the STSAT-2 project are to obtain the solar Lyman-alpha image for solar study and to provide the satellite laser ranging for validation of the launch vehicle’s performance of inserting a satellite to its desired orbit. Other the main mission objectives, STSAT-2 will perform optimizing the technologies proven throughout the small satellite projects previously developed by the SaTReC, and testing advanced bus technologies for small satellites. To develop and test the innovative technologies, the STSAT-2 spacecraft bus system shall 1) adapt the frame-type structure and electronics boxes, 2) use composite material solar panel, 3) improve the previous start sensors to the dual-head type to achieve higher performance, 4) develop a high-precision CCD digital sun sensor, 5) include a pulsed plasma thruster (PPT) to test the attitude and orbit control, 6) utilize a compact on-board computer (OBC) with a simplified network structure, and finally 7) improve the X-band transmitter to provide up to 10 Mbps data link. Through the above technology developments, STSAT-2 bus system will provide the compact, stable, and optimized bus technologies that can be used for further small satellite missions afterwards.
