Analytical conditions of coefficients of the equations set for providing the stability of the process of magnetic discharge in flywheel engines are derived. The problem on synthesis of programmed control of hyrodynes to make a fast deployment of spacecraft for Earth remote sensing is considered. A nonlinear control equation is derived in an explicit form and an algorithm for determining angles of the hyrodyne frames rotation providing a desired programmed motion of the spacecraft is developed. Models of ephemerid astronomy are analyzed with respect to the small satellite dynamics and control. Models for including the Earth precessional and nutational motion and for calculating the Sun visible position are derived. Algorithms to calculate the small satellite dynamics are developed and packages for calculations of external force fieldsare created. A mathematical model of spacecraft motion when orbital transferring in space is examined. Necessary optimal conditions for the case of a given coplanar plane of the spacecraft controlled thrust vector are determined. Algorithms for solution of boundary problems to calculate optimal transfer trajectories are developed. Applications - control of advanced space objects.
