Due to the increasing complexity of information processes, there is a need to develop models and methods of interaction between various subsystems, segments and, in relation to them, to develop methods for identifying ob-jects. The object of research is the process of accounting for the movement of material objects between different segments of complex systems, for example, between different segments of the international space station, between different segments of the material flow system or other segments of the Earth-Space system. Instruments and instrument complexes were chosen as material objects. Based on the performed study of data structure complexity levels, the necessity of development of identification systems for different segments of the material flow transportation system was substantiated. A new method is proposed and the results of practical experiments on the identification of material objects on the basis of CCSDS standard (CCSDS RFID Tag-Encoding Yellow Book) are considered. The hardware platform for accounting of tangible objects and information collection was selected radio-frequency readers and on-board computer networks represented by CCSDS 881.1-B-1 (Spacecraft onboard interface services - RFID tag encoding specification). RFID tags are used to identify tangible objects. To solve the problem of transferring information about material objects the developed model of information exchange and method of identification of material objects are presented, necessary fields and tag's memory bank structure are presented. In the process of describing the identification of material objects it is proposed to use a special alphabet ECMA-113 for data representation in the identifiers placed in the RFID tags. As part of the study, the simulation of information exchange between different subsystems during the transfer of information about material objects was conducted. The results of the experiments are presented, confirming that the universality of the alphabet lies in the possibility of simultaneous use of Latin and Cyrillic coding. For an estimation of efficiency of the offered models and modelling of a situation of an exchange of the information on material objects in wireless on-board networks separate independent subprogrammes of coding, decoding of identifiers of material objects have been developed and practical modelling of transfer of the big information volume between two various agencies (segments) is spent. The programmes were developed by the participants independently
of each other. On the basis of fulfilled modeling of information interaction and information transfer on material objects it was found that the error of data recognition does not exceed 6-7% and it does not increase with the increasing number of objects. The development results allowed to formulate a conclusion about the success of the experiment on the application of object identifiers based on CCSDS for airborne wireless networks, for the use of radio-frequency identification systems.
