The satellite's sole instrument is a radar device called a scatterometer, which will continually sweep the ocean tops that cover two-thirds of the world and measure the speed and direction of the winds that stir them.

He was in charge of the efforts to demonstrate that the instrument package containing a radar altimeter, windfield scatterometer, synthetic aperture radar, scanning multichannel microwave radiometer, and a visual and infrared radiometer, met all specification for measuring geophysical parameters over the ocean.

On July 7, eighteen days after take-off, the scatterometer was turned on and a team of 12 personnel made detailed reviews of function of QuikSCAT . A month after entering orbit, the team completed the checks, and QuikSCAT began collecting and transmitting backscatter measurements.

Its mid-latitude orbit meant it was able to collect data about the same spot on Earth at different times of day, whereas the Sun-synchronous orbits used by other scatterometer-equipped spacecraft would re-visit the same location on Earth at the same time daily.

A work, published by the journal " Science " in May 2004 with the title " Wind as a Long-Distance Dispersal Vehicle in the Southern Hemisphere ", used daily measurements of wind azimuth and speed taken by the "'SeaWinds scatterometer "'from 1999 to 2003.

On the other hand, the Remote Sensing Malaysia is equipped with computer system for satellite data image processing, global positioning system, satellite ground receiving station for real time data acquisition, microwave remote sensing laboratory ( anechoic chamber, mobile scatterometer ), remote sensing digital photographic laboratory and remote sensing data archiving and retrieval centre.

Later additions to these passive microwave observations are the Tropical Rainfall Measuring Mission ( TRMM ) Microwave Imager ( TMI ) and the Advanced Microwave Scanning Radiometer of NASA s Earth Observing System ( Aqua ( satellite ) ) AMSR-E . The scatterometer ( e . g . the Quick Scatterometer ( QuikSCAT ) ), which is active by nature, uses microwave radar and retrieves both wind speed and wind direction.

QuikSCAT is being used in this reduced mode to cross-calibrate other scatterometers in hopes of providing long-term and consistent surface wind datasets over multiple on-orbit scatterometer platforms, including the operational Indian Space Research Organization ( ISRO ), and the China's HaiYang-2A ( HY-2A ) scatterometer operated by China's National Satellite Ocean Application Service, as well as future NASA scatterometer missions in development.
