Japanese Earth Resources Satellite 1 (JERS-1) was a satellite launched in 1992 by the National Space Development Agency of Japan (NASDA, now part of JAXA). It carried three instruments: An L-band (HH polarization) synthetic aperture radar (SAR); A nadir-pointing optical camera (OPS); A side-looking optical camera (AVNIR). The satellite operated until 1998 and re-entered the Earth's atmosphere in 2001.
