Wsf-m on-orbit cal/val techniques

The on-orbit calibration of the WSF-M MWI microwave radiometer will include orbital maneuvers to estimate parameters that are difficult to accurately determine on the ground before launch. The planned orbital maneuvers are similar to those previously used for the GMI sensor and consist of a deep-space pitch maneuver, an inertial hold maneuver, and a nadir pitch maneuver. To prepare for the upcoming launch and calibration period, we simulate all calibration maneuvers, estimate the calibration parameters of interest from the simulated data, and evaluate the accuracy of the extracted parameters.
