Based on the research of the National Aviation University, organizational methods are proposed for implementation in the form of mon-itoring and accessibility of the radio navigation field, as well as technical solutions for ensuring the integrity of GNSS information — adaptive control of the radiation pattern, which is the most effective solution to ensure the availability and integrity of navigation information for consumers.Item Informative Support of Acceptance of Administrative Decisions is on the Basis of Integration of Productive Data(2017) Павленко, Петро МиколайовичItem Method of evaluation of the electric field level of dangerous signals to gnss receivers(National Aviation University, 2018-06) Швець, Валеріян Анатолійович; Харченко, Володимир ПетровичPurpose: It is necessary to develop and test a method for estimating the dangerous signals level to GNSS receivers in order to make a decision on the possibility of fulfilling the target function of the GNSS radio receiver under the influence of interference and to solve the navigation problem. Method: the approach is based on the analysis of the electromagnetic environment, the statistical criteria for optimal detection and instrumental measurements. Results: the article uses the basis of normative documents on the application of GNSS to propose a method for estimating the state of the electromagnetic environment at the location of the GNSS radio receiver in order to make a decision on the possibility of performing the target function by the radio receiver of navigation signals. The proposed method was tested at the National Aviation University.

Methods: the approach is based on the theory of random processes and adaptive signal processing. Results: the proposed method of direct calculation of the inverse correlation matrix has shown the possibility of carrying out such calculations without a prior knowledge of the interference direction, the correlation function of the interference, and also the spectral characteristics of the interference. The method allows to reduce the calculation time of the inverse correlation matrix and eliminate the errors caused by constructive inaccuracies of the radio channels of the adaptive antenna array, which in turn reduces the error in measuring the direction of the interference source. Discussion: the method is suggested in order to ensure availability and consistency of network satellite systems’ navigation data.Item Radio receiver for the monitoring of the radionavigation field of global navigating satellite systems(Praha, Czech Republic: Sciences of Europe, 2019-02-28) Швець, Валеріян АнатолійовичThe safe operation of transport, as an object of critical infrastructure, on the basis of GNSS signals depends on the accuracy of determining the coordinates of the user of navigation information, which depends on the accuracy of the assessment of atmospheric parameters and the surrounding electromagnetic environment.
