Daki O. Theoretical bases of automation of technical condition monitoring radio navigation complexes on water transport means. - Qualification scientific work as a manuscript.

Thesis for a doctoral degree in technical sciences: Speciality 05.22.20 «Operation and repair of transport means» (05 – Technical sciences). – State university of infrastructure and technologies, Kyiv, 2020. The aim of the study is to increase the reliability and efficiency of monitoring technical condition of radio navigation complexes on water transport means due to the development of complex-formed test signals methods of synthesis and processing. Scientific novelty of the results obtained in the dissertation is as follows: the method of justifying the criteria for optimality of test signals synthesis has been further developed; the methods of input test signals synthesis have been obtained for the first time; the methods of the test signal response processing for radio navigation complexes on water transport means have been further developed; the method of synthesizing test signals with the necessary spectrum using Lagrange function has been further developed; the method of determining coordinates errors on water transport means, depending on the procedures of monitoring the technical condition of radio navigation complexes, has received the further development. Compared to the known rectangular signals, the time gain due to the application of the proposed signals is up to 40% with a short monitoring time and up to 20% with increased monitoring time. The increased reliability of technical condition monitoring radio navigation complexes on water transport means is up to (10…15)% with a short time of monitoring and up to (5…10)% with considerable time of monitoring.
