20.500.12556/RUL-127273 A comparative analysis of the response of GNSS receivers under vertical and horizontal L1/E1 chirp jamming Jamming is becoming a serious threat to various users of global navigation satellite systems (GNSS). Therefore, live monitoring tests are required to estimate the sensitivity range of GNSS receivers under jamming. This study analyses the response of some mass-market and professional-grade receivers to intentional interferences based on different 3D jammer positions. First, the vertical jamming was investigated, followed by a horizontal experiment where the receivers were placed at three locations while the jammer was moving within a triangular area. The aim was to determine a fingerprint of the influence of the L1/E1 chirp jammer on receivers used in the research. The results show that low-cost receivers are much more susceptible to interference, while the latest generation of GNSS geodetic receivers are much more resilient. It is encouraging that positioning in the presence of jamming could be achieved on a larger scale, especially by using professional receivers. An attempt to position the jammer will be left for trials when a more frequency stable device is applied. intentional interference geodetic receivers vertical/horizontal jamming profile L1/E1 chirp jammer low-cost GNSS receivers geodetski sprejemniki GNSS sprejemniki motnje motnje zvoka true false true Angleški jezik Slovenski jezik Članek v reviji 2021-06-01 12:06:36 2021-06-01 12:06:36 2022-09-06 03:50:28 0000-00-00 00:00:00 2021 0 0 23 str. iss. 4, art. 1446 Vol. 21 Feb. 2021 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 528.8 1424-8220 10.3390/s21041446 52583171 RAZ_Pavlovcic_Preseren_Polona_2021.pdf RAZ_Pavlovcic_Preseren_Polona_2021.pdf 1 88DD21C29CACCC8D98780A2A0B8F16AB 19588ccc6c293eebf47deb651ab7fe121dcf294ef214a4665b9e6409e9d5e014 419826a2-92fa-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153929 https://www.mdpi.com/1424-8220/21/4/1446 1 f93f10c6-c2c1-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143593 Fakulteta za gradbeništvo in geodezijo Fakulteta za pomorstvo in promet 0 0 0
