Study on the Distributed Framework of Integration Space and Ground Simulator

Considering the requirement to build space and ground integrated training, mission command and decision-making space flight simulator, with the development of manned space engineering, a standards-based HLA astronaut training, command and decision-making integrated space and ground simulator distributed architecture was presented. Firstly the system structure composed of the spacecraft, telemetry stations, command and control centers and ground-based training simulator is introduced. space and ground data link nodes and the data conversion process were elaborated. Then the distributed interactive implementation strategies between simulation data and flight data under three modes of space and ground online, offline and mixed-mode are analyzed. The causes and solutions of difficulties in application of the system are analyzed, discussed and tested. The system will further improve the existing simulator architecture, based on real flight data, the super-real-time flight missions is forecasted and fit, also can provide an important guarantee for collaborative mission training and real-time command and decision-making.
