Instruments
Windsat, Passive Polarimetric Microwave Radiometer
A highly sensitive 6.8 to 37 GHz receiver for measuring ocean surface wind
speed and direction. Provides risk reduction data for the National Polar-orbiting
Operational Environmental Satellite System (NPOESS) development of the Conical
Microwave Imager Sounder (CMIS). WindSat is 3.3 meters high with a mass of
305 kg, and it includes a 125 kg rotating platform that spins about the Earth-
pointing yaw axis at 29.6 RPM.
Solar Mass Ejection Imager (SMEI)
A 35 kg all-sky camera experiment for imaging Coronal Mass Ejections (CME)
propagating from the sun through the solar wind. 4π steradians of sky coverage is
provided per orbit.
