QuikSCAT (abbreviation of Qui c k Scat terometer ) is an observation satellite of NASA , whose task it was for the NOAA information on the wind speed and direction over the oceans to collect. The mission was launched at short notice because the NSCAT instrument on board the Japanese ADEOS-I satellite had not transmitted any data since June 1997 due to a power failure . QuikSCAT was launched into sun-synchronous Earth orbit on June 20, 1999 on a Titan II from Vandenberg Air Force Base .
QuikSCAT was part of the Earth Observing System , a long-term research program run by NASA.
Although designed to last for two years, QuikSCAT operated for over ten years until the mechanism for rotating the scatterometer antenna failed on November 23, 2009. This reduced the swath width to 30 km so that large-area measurements were no longer possible. Nevertheless, QuikSCAT remained in use and served as a standard for calibrating new satellites. On October 2, 2018, the satellite was finally switched off.
