Development and operation of the IRMSS and CCD camera for CBERS

摘要

The Infrared Multispectral Scanner (IRMSS) and the CCD Camera were two of the three remote sensing payloads for China-Brazil Earth Resources Satellite (CBERS). This paper introduces their development and operation. The IRMSS is a scanning imaging multispectral remote sensor. It has 4 bands, one panchromatic band (0.50～0.90μm), two short-wave infrared bands (1.55～1.75μm, 2.08～2.35μm) and one long-wave infrared band (10.4～12.5μm). Its swath is 120km. The pixel resolution of the panchromatic band and short-wave bands is 78m while the long-wave infrared band is 156m. The CCD Camera is a pushbroom multispectral remote sensor. It has 5 bands, i.e. 0.45～0.52μm, 0.52～0.59μm, 0.63～0.69μm, 0.77～0.89μm and 0.51～0.73μm. Its swath is 113km and pixel resolution is 20m. The development of the IRMSS and the CCD Camera took about 11 years. On October 14, 1999 the two sensors were sent into orbit. The in-orbit test proved that they had met their specifications.
