TDK-7ST3 and TDK-7ST4 simulators are designed to train crews for piloting Soyuz-TMA spacecraft at all flight stages, including:

• prelaunch preparation of the transport vehicle;
• orbital ascent;
• orbital maneuvering;
• rendezvous, final approach and docking, flight in mated configuration with ISS;
• undocking from the ISS;
• de-orbiting;
• landing and final operations carrying out.

Each TDK-7ST simulator represents a complex close-to-real simulator, built using full-size mock-ups of habitable compartments of the transport manned spacecraft Soyuz. The simulator provides realistic simulation of operation of all necessary on-board systems and motion of the vehicle as well as a comprehensive visual model of the outside situation, which can be observed through optical and television monitoring assets of the descent module.

Integrated simulators provide solution of the following tasks:

• both full training from launch to landing and training sessions of individual flight stages;
• off-nominal situations simulating of all spacecraft systems in both manual and automatic ways;
• flight simulation in both real and fast time-scale (1:1, 2:1, 4:1, 10:1);
• crew activity and status monitoring using television systems, voice communications and health control;
• video recording of the training, which pieces can be played back, if necessary, during the post-training debriefing;
• particular space flight support;
• continuous 12-hour simulating sessions;
• simulator fault recovery in 5 min. in case of either power failures or improper actions of operators.
