A parametric approach is proposed for the satellitetrajectory tracking problem by using the eigenstructure assignment theory and the model reference theory of linear systems.
They said the satellite did not have a booster mechanism to correct its trajectory.

The most efficient launch trajectory is due east from a launch site, which places the satellite into an orbital inclination equal to the latitude of the launch site.
