Aa. Martynyuk et Vg. Miladzhanov, The theory of stability of an orbiting observatory with gyroscopic stabilization of motion, INT AP MECH, 36(5), 2000, pp. 682-690
The method of Lyapunov's matrix functions is used to establish the stabilit
y conditions for a spacecraft. A control system with exesutive devices in t
he form of three gyroscopic frames orients the spacecraft in inertial space
.
