Investigation goal - Development of mathematical models and algorithms of autonomous estimation of current dynamic parameters of mathematical models of OSS angular motion regularly functioning under flight conditions. Investigation methods - methods of theoretical mechanics, control under uncertainty, linear algebra and optimization, motion stability, quaternion theory. Obtained results: Methods and algorithms for on-line estimation of current values of the inertia tensor and position of center of mass of small spacecrafts under flight conditions are developed. The obtained estimates can be directly used in intellectual high-precision systems of OSS attitude control with dynamic parameters unpredictably changing during flight. It is proposed to realize the algorithms using typical on-board measuring and command units of OSS motion control systems.
