The problem of attitude optimal control a spacecraft as solid body with the energy spent on maneuvering taken quadratic functional, and fixed transition time, is investigated. dynamic configuration boundary conditions an angular velocity are arbitrary; function not limited. According to Poinsot concept from theoretical mechanics interpretation motion around point help Pontryagin maximum princip...

The SPAcecraft SIMulator (SPASIM) simulates the functions and resources of a spacecraft to quickly perform conceptual design (Phase A) trade-off and sensitivity analyses and uncover any operational bottlenecks during any part of the mission. Failure modes and operational contingencies can be evaluated allowing operational planning (what-if scenarios) and optimization for a range of mission scen...

New approach for modelling a physical hysteresis damping the flexible spacecraft structure oscillations, is developed. New results on communication satellite attitude guidance and digital robust control with precise pointing the large-scale flexible antennas, are presented.
