20.500.12556/RUL-131836 Robustness against chirp signal interference of on-board vehicle geodetic and low-cost GNSS receivers Robust autonomous driving, as long as it relies on satellite-based positioning, requires carrier-phase-based algorithms, among other types of data sources, to obtain precise and true positions, which is also primarily true for the use of GNSS geodetic receivers, but also increasingly true for mass-market devices. The experiment was conducted under line-of-sight conditions on a straight road during a period of no traffic. The receivers were positioned on the roof of a car travelling at low speed in the presence of a static jammer, while kinematic relative positioning was performed with the static reference base receiver. Interference mitigation techniques in the GNSS receivers used, which were unknown to the authors, were compared using (a) the observed carrier-to-noise power spectral density ratio as an indication of the receivers’ ability to improve signal quality, and (b) the post-processed position solutions based on RINEX-formatted data. The observed carrier-to-noise density generally exerts the expected dependencies and leaves space for comparisons of applied processing abilities in the receivers, while conclusions on the output data results comparison are limited due to the non-synchronized clocks of the receivers. According to our current and previous results, none of the GNSS receivers used in the experiments employs an effective type of complete mitigation technique adapted to the chirp jammer. precise GNSS position determination carrier-phase positioning interference mitigation geodesy visokonatančno določanje položaja z GNSS fazno pozicioniranje odstranjevanje interference geodezija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-10-04 13:00:17 2021-10-04 13:00:20 2022-09-10 04:14:05 0000-00-00 00:00:00 2021 0 0 20 str. iss. 16, art. 5257 Vol. 21 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 528.8 1424-8220 10.3390/s21165257 73401091 RAZ_Dimc_Franc_2021.pdf RAZ_Dimc_Franc_2021.pdf 1 5ADB04412F3ECBD838863B0C8F00BED9 1e6d5821c2dc0673b2d00a9ec01c528c9e30d2129b80b360c04c4a7b0b0c95d1 05a9c019-b66d-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155453 https://www.mdpi.com/1424-8220/21/16/5257 1 f9d7ee92-2501-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149251 Fakulteta za pomorstvo in promet Fakulteta za gradbeništvo in geodezijo 0 0 0
