Abstract
Global Satellite Navigation Systems (GNSS) are widely used positioning tools to monitor and navigate an object in space. The dynamic development of geoinformation technologies, in which the object location component is essential, also forces the continuous development and improvement of GNSS positioning algorithms and methods. As part of this development, one of the most critical elements is the broadly understood security of the use of GNSS positioning technology, in particular, to protect system users against malfunctions of the GNSS system caused by intentional (jamming, spoofing) and accidental (e.g. interference, navigation data errors) disturbances of measurement signals. Hence, appropriate countermeasures for GNSS signal disturbances are essential for its reliable operation.<br><br>In this study, the robustness of the measurement data acquisition and processing algorithms to signal disturbances is investigated in detail. The tests were carried out using the GNSS Spirent GSS9000 signal generator and the NaviSoC receiver by ChipCraft Sp. z o.o. (a spin-off company of the Warsaw University of Technology). The paper presents the analysis of the detection, characterization, and mitigation of GNSS signal interference. Also, the impact on multi-GNSS positioning accuracy and reliability is discussed in detail.&nbsp;
