The concept of «observability in the small» for dynamical systems in case of nonautonomous (nonstationary) linear systems is systematically considered for the first time. A theoretical problem of principal observability «in the small» of a third-order linear non-autonomous system and its application for analyzing the observability of small spacecraft is considered. A special case of «observability in the small» of the general theory of control and observation meets physical and technical features of small spacecraft operation. The aim of the work is to solve the problem of observability of dynamic systems, in particular, small spacecraft under certain restrictive conditions, and demonstrate the effectiveness of the solution using a real example.
Key words: observability «in the small», controllability «in the small», linear non-stationary system, small spacecraft.
