Model of Onboard Heterogeneous Data Storage System Functioning with the Consideration of Different Information Importance

In article presented the model of Earth remote sensing satellite heterogeneous onboard storage system function. The main difference of model is the fact of considering stored data importance. Model can be applied for analyses of different structures of data storage systems and ways of storage for different stages of lifecycle (from constructing to exportation). Modelling of data storage system function based on decomposition information processes of system, detection their interconnections and dependences of quality indicators from system structure and ways of storage.
