Status of the correlation process of the V-HAB simulation with ANITA ISS data

The Virtual Habitat (V-HAB) is a dynamic Life Support Systems (LSS) simulation suite currently under development at the Institute of Aeronautics at Technical University Munich (TUM). The aim of this project is to develop a comprehensive, dynamically adaptable tool to simulate the living and working environment of crew members during long duration space missions. One of the most important issues for each simulation is the plausibility. To validate the V-HAB simulation the comparison of the simulated results with real data should be performed. The International Space Station (ISS) is the ideal candidate to validate the simulation. The ISS experiment ANITA has provided the unique transient data about the air composition in the ISS during the long period of time in very high resolution. Using this data the correlation process of the V-HAB has been initiated. The correlation process will be made in several stages: modeling of all necessary ISS technologies; preparing of the ISS LSS model; performing simulations and comparing with real data; improving of the models to achieve better correspondence with real data. This paper gives the status of the correlation process. In particular the models of the technologies are shown with significant test cases. Last but not least the V-HAB model of ISS is presented. The results and findings of both, module level and system level modeling are critically discussed.
