GraceAntennaCenterCorrectionArcCovariance
This program computes covariance information for the nonÂ-stationary noise of the KBR antenna offset correction (AOC) from the orientation covariance matrices provided in Level-1B products via variance propagation. By using the output outputfileSatelliteTrackingCovariance in PreprocessingSst, noise model distinguishes between the stationary noise of ranging observations and the nonÂstationary AOC noise.
The covariances are derived from the partial derivative of the AOC w.r.t. the roll/pitch/yaw rotations and star camera covariances inputfileScaCovariance1 and inputfileScaCovariance2.
The covariances for the range-rates and range-acceleration are computed by differentiating an interpolation polynomial of degree interpolationDegree.
