Attitude maneuvers for mightysat II.1 hyperspectral data collects

摘要

The characteristics of the Fourier Transform Hyperspectral Imager on MightySat II.1 have a significant effect on the attitude maneuvers required for data collection. In order to obtain the desired image characteristics for a given group of instrument settings the velocity of the swath across the ground must be precisely maintained. This requires the spacecraft to maneuver constantly during the data collection. This paper examines the design of the attitude maneuver and how the differnet instrument settings affect the required attitude maneuver. The image characteristics for the different instrument settings are also examined.
