Seasat
SEASAT (SEASAT) was designed by the American Aeronautics and Space Administration for the first time from the orbit to observe the ocean and is a satellite equipped with synthetic aperture radar. The mission was to collect know-how in observing oceanographic events on a global scale and managing oceanographic observations with satellites. Observation items range from ocean surface wind and sea surface temperature, wave height, internal wave, water vapor, sea ice, ocean cross section and so on. Cisat was managed by NASA's Jet Propulsion Laboratory and was launched on June 28, 1978 in a near circular orbit with an altitude of 800 km orbital inclination angle of 108 degrees. CIsat was operated for 105 days until October 10, 1978 because the electric system was short circuited. Seasat had five main observation instruments to gather the greatest information from the ocean surface. : ▪ Radar altimeter to measure the altitude of the satellite from the sea surface ▪ ...
