Abstract-We suggest an original method of problem-oriented integration of SMP-models allowing to unite different manufacturer's models in one complex. The method consists in adding to the SMP-models structural-parametric and functional description creating a semantic level of presentation of a modeled object. Implementation of this method allows to solve the tasks of compatibility and interoperability of the SMP-models in the problem-oriented infrastructure of simulation modeling. The infrastructure is designed for the work of spacecraft onboard equipment designers.
We have designed a technology for creation of the space systems' onboard equipment simulation problem-oriented infrastructure, based on the Simulation Model Portability standard. The simulation infrastructure is a software environment allowing to create, integrate and use simulation models of different purpose including those of different manufacturers'.The infrastructure includes software components, specifications, simulation models and the results of tests, as well as the knowledge bases consolidating knowledge and experience of the experts in space systems' onboard equipment creation. Our product will help to increase the quality and validity of designer solutions at different stages of the space equipment production lifecycle.
The paper discusses the software package developed by the authors and designed for automated assessment of data quality indicators of optical-electronic satellite imagery. The program implements the possibility of both a priori and a posteriori determination of the main spatial-frequency and radiometric characteristics of recorded images, which makes it possible to compare (verify) the declared and actual parameters of the imaging equipment. In the first case, the calculation of the predicted image quality is performed by the method based on simulation modeling of all elements of the imaging system, including modeling of the spectral irradiance of the earth's surface and taking into account the transfer characteristics of the atmosphere. In the posteriori assessment, it is used the method that allows us to establish quality indicators in the process of analyzing the contrasting brightness differences present on the image on the border of homogeneous objects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
