Seasat [3] was the first Earth-orbiting satellite designed for remote sensing of the Earth's oceans and had on board one of the first spaceborne synthetic-aperture radar (SAR). The mission was designed to demonstrate the feasibility of global satellite monitoring of oceanographic phenomena and to help determine the requirements for an ...

Jun 14, 2012 · SeaSat (also referred to as SeaSat-A prior to launch and SeaSat-1 after launch) is a pioneering Earth observation experimental mission of NASA/JPL; the first ever civilian spaceborne imaging radar instrument (SAR) was flown on SeaSat in 1978.

Seasat was the first satellite designed for remote sensing of the Earth's oceans with a variety of microwave instruments, including an ocean radar altimeter for measuring sea surface height, a scatterometer for measuring surface winds, a Visible/Infrared Radiometer, and a synthetic aperture (imaging) radar.

Seasat operated in Earth orbit for 105 days, measuring sea-surface winds and temperatures, wave heights, atmospheric liquid water content, sea ice features and ocean topography, before a massive short circuit in the spacecraft's electrical system ended the mission on October 10, 1978.

Seasat was the first satellite designed for remote sensing of the Earth’s oceans with synthetic aperture radar (SAR). The mission was designed to demonstrate the feasibility of global satellite monitoring of oceanographic phenomena and to help determine the requirements for an operational ocean remote sensing satellite system.

Seasat was a NASA oceanography experimental mission. It was launched on 28 June 1978 and ceased operations that same year. On board was the first-ever spaceborne synthetic aperture radar (SAR) system for science applications.

NASA's Seasat was the first Earth-orbiting satellite specifically designed for the remote sensing of the global ocean, and carried NASA’s first synthetic aperture radar (SAR) into orbit.

Mar 31, 1991 · Seasat, in orbit during 1978, was the first satellite to include a radar altimeter for mapping sea-surface topography. The resulting improvements to the global marine geoid allowed computation of its first vertical derivative, the marine free-air gravity field, at wavelengths as short as 50 km and as long as 1000 km ( Haxby et al., 1983 ).

Oct 10, 1978 · Seasat, experimental U.S. ocean surveillance satellite launched June 26, 1978. During its 99 days of operation, Seasat orbited the Earth 14 times daily. Instruments of the unmanned spacecraft, engineered to penetrate cloud cover, provided data on a wide array of oceanographic conditions and features, including wave height, water temperature ...
