JERS (Japanese Earth Resources Satellite)


JERS (Japanese Earth Resources Satellite) was a Japanese Earth observation satellite launched by NASDA (National Space Development Agency); also known by the national name Fuyo. Following on the success of MOS, JERS tested the performance of optical sensors and a synthetic aperture radar, and made observations for use in land survey, agriculture, forestry, fishery, environmental preservation, disaster prevention, and coastal surveillance. Some of its data were shared with the University of Alaska for research purposes.
