Attitude Simulation During 'MIR' Orbital Complex Flight Tereshina, I.N. Tel.: 513-51-37 RSC/Russia Abstract: We review some questions concerned with Simulation and computation of attitudes for 'MIR' Orbital Complex. Some methodical questions concerning selection of attitudes for realization of different scientific experiments for docking and undocking phases with transport spaceship 'Progress', cargo spaceship 'Soyuz' and Shuttle are considered here. We describe some restrictions and requirements to 'MIR' orientation during different phase of 'MIR' flight and show application of created softwaree for computation of attitudes on examples.
