The ocean-mapping satellite was Seasat 1, launched by the United States on June 26, 1978. The mission was to radar map the surface of the ocean, providing precise information on tides, currents, storms, undersea seismic activity, and other phenomena that affect sea level. It sampled the sea height every 3 kilometres along its orbital track, which covered the majority of the ocean surface every three days. A global ocean-surface map was later prepared from the data.
