Scientific paper

This paper describes some recent results concerning the effect of rotation of the upper atmosphere (superrotation) on the attitude motion of spacecraft. From the data taken by several satellites, an approximate model of the atmospheric rotation rate as a function of altitude has been developed. An approximate, closed-form analytical description is obtained of the attitude motion of a momentum-biased, near-earth spacecraft which is subjected to an aerodynamic torque that includes the contribution from superrotation of the atmosphere. Results from the analysis are compared with simulation and flight data and are found to be in close agreement.
