Optical Sensor Assembly (OSA)

OSA had a primary mirror aperture of 70 cm and a folded optical focal length of 10 m using five mirrors. The detectors at the focal plane included a panchromatic sensor with 13,500 pixels cross-track, and four multispectral sensors (blue, green, red, and near-infrared) each with 3375 pixels along-track. Its nadir image swath was 11.3 km.
