Attitude Determination And Control Of The "MIR" Orbital Complex During A Scientific Experiments M.Yu. Beliaev, N. I. Efimov, I. L. Lapshina RSC Energiya, Kaliningrad, Moscow, 141070 Russia Abstract: The methods of attitude determination and control of orbital complex "MIR" are described. The measurements data from different sensor configurations for attitude determination (magnetic, sun star) are used. The different cases of complex's motion (orbital and inertial stabilization, drift) are considered. The examples of using of the methods described are given.
