Earth observation satellites handle the observed data by transmitting them to the ground station or the data relay satellite director ies, or by temporarily stor ing them in the onboard memory box then transmitting them to the ground station later. All data are received by the ground receiving antenna-device of the ground station and archived in magnetic tapes or hard discs. Some data are also archived in another station.
In Japan , the JAXA Earth Observation Center (EOC), Hiroshima Institute of Technology , and Tokai University have the receiving and archiving centers (except for the meteorological satellites [NOAA] and [HIMAWARI]). EOC has the center for the USA Land sat data (1979-), MOS, JERS-1, and ADEOS etc.
Also, foreign data are stored in foreign governmental agenc ies such as EROS of USA, ESRIN of ESA, and compan ies such as Space imaging Co, Digital Glove Co, and Orb Image Co.
