The Coriolis mission is an STP flight P98-2 carrying Windsat and SMEI. Coriolis will use a Spectrum Astro SA-200HP bus and launch by Titan II. Windsat operates as a USN/ONR satellite managed by NRL under the STP, as part of the Coriolis mission. Windsat uses a polarimetric microwave radiometer to measure wind speed and direction; earlier missions did not have all the Stokes parameters and so could not determine direction. It has a 1.8m microwave reflector and horns operating at 10.7, 18.7 and 37 GHz. Horns at 6.8 and 23.8 GHz will measure only 2 of 6 polarization components.
Assembly by Det 12 STP/Kirtland, oprations at Kirtland for first year and then by NSOC Pt Mugu. Mass 377 kg bus, 827 kg total. 4.7h 1.3dia + panel. Cylinder + truss + panel. 82 kg propellant. First use of large 7.6m fairing on the Titan 2 SLV.
It was inserted into a 281 x 845 km transfer orbit on 2003 Jan 6 and used onboard propulsion to reach its operational 822 x 841 km x 98.7 deg orbit by Jan 18.
