SPOT High Resolution Visible Data Received at NASDA in Japan

Centre National de Etudes Spatiales, CNES, launched the first French earth observing satellite SPOT-1 as an operational, commercial satellite with two High Resolution Visible Imaging Instruments which are able to operate identically at the same time. The HRV can take oblique views using a position selection mirror with maximum viewing angle 27 degrees off the satellite track. In the case of nadir viewing, the swath width of each HRV is 60 kilometers. The Observing mode of HRVs is both panchromatic and multispectral. The spectral range and resolution is as follows: spectral mode band spectral range resolution ===================================================================== multispectral XS1 0.50 - 0.59 micrometers 20 meters XS2 0.61 - 0.68 micrometers 20 meters XS3 0.79 - 0.89 micrometers 20 meters panchromatic PAN 0.51 - 0.73 micrometers 10 meters The Earth Observing Center, NASDA, archives all data received. It then processes photographic and/or digital products on user demand. Request for reception is accepted 4 weeks before the observation.
