In article considered problem of onboard information accuracy increasing for storage system operating in various conditions. The subjects of research are onboard storage systems for Earth monitoring probes.
In article earth monitoring probes presented as information system. Considered aspects of information accuracy and correctness increasing. Increasing of information correctness leads to information accuracy.
Target of article is research of algorithm of information storage management in heterogeneous data storage systems for prospective space probes. Algorithm should take in to account significant and relevance of stored information and condition of data storage system.
As result proposed approach to management of information storage according to information lifetime cycle. Described mechanic of data storage that maintain demanded level of correctness.
Existing in data storage system heterogeneous nodes allows flexible management of stored data that leads to decreasing of information redundancy in system. Management of storage means management of system structure and dynamic management of network coding settings.
Importance of practical usage is that Algorithm with some modifications may be applied to any prospective data storage system, that works in adverse conditions. Main objects for algorithm application seems data storage systems with critical information.
Algorithm allows to maintain data correctness in condition of system degradation.
