The initial checkout of MSC (multi-spectral camera) system

Multi-Spectral Camera(MSC) is a payload on the KOMPSAT-2 satellite to perform the earth remote sensing. The instrument images the earth using a push-broom motion with a swath width of 15 km and a ground sample distance (GSD) of 1 m over the entire field of view (FOV) at altitude 685 Km. The instrument is designed to have an on-orbit operation duty cycle of 20% over the mission lifetime of 3 years with the functions of programmable gain/ offset and on-board image data compression/storage. KOMPSAT-2 was launched on July 28 2006 and stared early operation including Initial Activation and Checkout(IAC). During IAC phase, MSC was checked and tested by prepared procedure. In this paper, the preparation, the sequence and the procedure of MSC initial activation checkout including SOH (State Of Health) are described. The activities including the checkout results during IAC as parts of Launch & Early Operation Period (LEOP) are discussed and analyzed.
