VEHICLE TRACKING ERRORS IN INTEGRATED GPS/GPRS TECHNOLOGY AND INS SYSTEM

Diplomsko delo obravnava področje uporabe navigacijske tehnologije v cestnem prometu na primeru sledenja vozil. Na kratko opisuje razvoj globalnega navigacijskega satelitskega sistema in strukturo GPS sistema, ki se uporablja danes. Poudarek diplomskega dela je na integraciji GPS tehnologije z inercialnim navigacijskim sistemom za izboljšanje natančnosti pozicioniranja vozila. Raznolikost in uporaba MEMS inercialne navigacijske tehnologije, kot nadomestek GPS tehnologije v okolju šibkega navigacijskega signala ali ob kratkotrajni popolni prekinitvi signala, je dandanes obvezna in prisotna v vseh napravah za sledenje ter natančno pozicioniranje vozila. Delo vsebuje primer uporabe strojne in programske opreme za sledenje vozil podjetja Telargo d.o.o. in model upravljana voznega parka ter podaja smernice razvoja tehnologije za prihodnost.The diploma thesis presents the field of the usage of navigation technology in land vehicle navigation system in case of vehicle tracking. Briefly describes the development of global navigation satellite system and the structure of the GPS system used today. The focus is on the integration of GPS technology with the inertial navigation system to improve the positioning accuracy of the vehicle. Diversity and the use of MEMS inertial navigation technology, as a substitute to GPS technology in weak signal environments and also during short GPS signal outages is now mandatory and is present in all devices designed for land vehicle tracking and precise positioning. The work contains an example of hardware and software manufactured by Telargo Ltd. Company for the purpose of vehicle tracking and fleet management and provides guidelines for future technology development
