Methodology for Positioning of GNSS Interference Detector

Abstract

This paper focuses on the increasing possibilities of detecting GNSS interference. The interference could significantly harm the user of GNSS signal, which can be used even for safety related services. Therefore, there is an increasing need for system capable to detect the GNSS interference. Moreover, when the protected area is larger, such as airport or perimeter of a military base, the need for correct positioning of the interference detection system is of the same importance as the system capabilities. In this paper, methodology for detector stations arrangement is evaluated to enable maximum benefits, i.e. to limit the risk of a failure to localize the position of the source of GNSS interference. The methodology could be used for any type of interference detector to propose optimum arrangement of the detector stations and to evaluate overall coverage of the specific interference detector constellation.
