Neural network analysis of telemetry data of on-board equipment of space crafts

Abstract

Goal. Research and development of methodology and software tools of machine automated analysis of telemetry data of onboard equipment (OE) of space crafts (SC). Research methods. The developed software tools and methodology are based on the machine learning, neural networks and image processing methods and algorithms. Results. The paper presents solutions for the actual tasks of machine analysis of telemetry data of OE SC with the purpose of detecting the states of its functioning and analyzing the reliability and operability. Software tools and methodology of neural network clustering-classification analysis of OE SC telemetry data based on the application of the neural networks such as the Kohonen SOM and image processing methods have been developed. The software tools were implemented in desktop and web versions and has a flexible modular service-oriented architecture. Conclusion. The presented software tools and the methodology of neural network analysis of OE SC telemetry data were tested on real telemetry data of the Belarusian spacecraft and the SC group AIST and showed the results with a confidence probability value of at least 0.9. The proposed tools of neural network analysis of the OE SC telemetry data make it possible to develop recommendations for improving the indicators of OE SC reliability during design and operation, detecting the OE SC states, making the correct control and operational decisions of the ground control complex. Key words: neural network, Kohonen SOM, image processing, modular service-oriented architecture, machine neural network telemetry data analysis, onboard equipment of space crafts.
