20.500.12556/RUL-150387 PRENOS ČASA V POMORSKI NAVIGACIJI TIME TRANSFER IN MARITIME NAVIGATION Glavni poudarek diplomske naloge sloni na procesu prenosa podatka o času, ki igra ključno vlogo v pomorski navigaciji. Ta proces se začne z ustvarjanjem natančnega časa v referenčnih inštitutih in se nadaljuje s prenosom referenčnega časa do končnih uporabnikov, bodisi prek žičnih ali brezžičnih metod. V teoretičnem segmentu smo natančno opisali ustvarjanje časovnega signala, ter njegovo prenašanje in sinhronizacijo s končnimi navigacijskimi napravami. Izpostavili smo raznovrstne izzive med prenosom, kot so oslabitev signala ali nepričakovane zakasnitve, in kako te problemi vplivajo na preciznost navigacijskih sistemov. Osnovna namera raziskave je bilo razumeti morebitne metode za izboljšanje točnosti časovnega prenosa in njegovi sinhronizaciji z navigacijskimi sistemi, ter ne zgolj doumeti teh težav. Za dosego želenega cilja smo uporabili deskriptivno in komperativno metodo analize, temeljito pregledali pisne in spletne vire ter preiskali obstoječe tehnologije. Kljub precizni tehnologiji smo ugotovili, da je ta lahko ranljiva za različne zunanje vplive in napade, kar nakazuje potrebo po neprestanem izboljševanju in inovacijah na tem področju. The primary focus of this thesis was on the process of transmitting time data which plays a crucial role in maritime navigation. This process begins with the generation of accurate time in reference institutes and continues with the transmission of this reference time to the end users, be it via wired or wireless methods. In the theoretical part, we described in detail how the time signal is generated, transmitted, and then synchronized with the final navigation devices. We highlighted various challenges that can occur during transmission, such as attenuation of the signal or unexpected delays, and how these problems affect the accuracy of the navigation systems. The main objective of the research was not only to understand these challenges but also to investigate possible methods to improve the accuracy of time transmission and its synchronization with navigation devices. To achieve this, we applied descriptive and comparative analysis methods, thoroughly investigated various written and online sources, and analyzed existing technologies. Despite the high accuracy of modern technologies, we found that they can be susceptible to various external influences and attacks, which underlines the importance of continuous improvement and innovation in this field. nastanek podatka o času žični in brezžični prenos časa satelitski prenos časa time data generation wired and wireless time transfer satellite time transfer time synchronization time transfer protection reliability of time transfer true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-09-16 08:45:06 2023-09-16 08:45:08 2025-11-06 08:33:12 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 34166 177666051 8315.pdf 8315.pdf 1 F595EF58764A85241725F8DF1141B9A7 a272dcf08cb3020e39dd7c73f8cc537882a7de61f106daa65dd291a0f33ac2e0 9369a3a0-545c-11ee-b1ae-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=174961 Fakulteta za pomorstvo in promet 0 0 0
