Errors Analysis of Rendezvous and Docking Training Simulation

Important errors existed in the consistency problem of ground training simulation with actual space flight in rendezvous and docking mission are investigated and countermeasures are put forward.Three characteristics of errors generated from simulation models,visual perception and operation perception are studied by focusing on astronauts’ perception in the loop.The influence of training simulation errors in both autonomous docking mode and manual docking mode on astronaut’s handling quality in real flight is analyzed in detail based on data of training samples,and approaches of model construction,midway-amending and identification are proposed.The statistic of simulation shows that the countermeasures are applicable,and the configurable bias of time delay and handling response in simulation are effective.The analyzing of simulation errors and countermeasures has a good application value for development of training simulator and astronauts’ training.
