The Multi-Spectral Camera (MSC) is a high spatial resolution imaging sensor which collects visible image data of the earth's sunlit surface. The MSC, the primary payload for the KOMPSAT-2, is a pushbroom-scanned sensor which incorporates a single nadir looking telescope. The sensor is submerged and rigidly attached to the spacecraft and the optical boresight of the telescope is aligned with the spacecraft +Z direction (nadir). The MSC collects PAN and MS monoscopic images of the earth. Stereoscopic images are made by ground processing of the images from multiple orbits. The MSC pointing is accomplished by rolling the spacecraft, as needed, so that the line of sight of the MSC may pass over the desired location or swath. At the nominal mission altitude with the spacecraft nadir pointing, the MSC collects data with a GSD of 1 meter for PAN and 4 meters for MS data and with a swath width of approximately 15 km. The MSC is designed to operate with a duty cycle of up to 20 % per orbit.
