System Note=update AltLabel Old Value=WindSat New Value=Satellite-based Polarimetric Microwave Radiometer WindSat is a joint NOAA Integrated Program Office/Department of Defense/NASA demonstration project, intended to measure ocean surface wind speed and wind direction from space using a polarimetric radiometer. It was launched aboard the Coriolis satellite by a Titan II rocket on 6 January 2003 into a 830-km 98.7-degree orbit, and is designed for a three-year lifetime.Group: Instrument_Details Entry_ID: WindSat Group: Instrument_Identification Instrument_Category: Earth Remote Sensing Instruments Instrument_Class: Passive Remote Sensing Instrument_Type: Spectrometers/Radiometers Instrument_Subtype: Radiometers Short_Name: WindSat Long_Name: WindSat End_Group Group: Associated_Platforms Short_Name: Coriolis End_Group Creation_Date: 2013-01-09End_Group 2019-04-29 15:24:54.0
