Abstract :
In order to achieve highly accurate calibration of the SeaWinds scatterometer, a calibration ground station (CGS) was constructed by Jet Propulsion Lab (JPL) at White Sands, New Mexico, in association with the QuikSCAT mission. This receive-only system precisely measures the time, frequency, and power of the SeaWinds transmit signal as it passes overhead. From the CGS data, key instrument and spacecraft parameters can be estimated. Since the launch of QuikSCAT in June of 1999, several key calibration results have been obtained, including a one second GPS error, and determination of instrument attitude, timing, frequency, and power
