The Current Status of Global Navigation Satellite Systems GNSS. Case Study: Comparative study of getting positions in Gaza City based on operating GNSS Systems.

GNSS applications in all fields play a key role, moving its use from navigation domain to multimodal use outdoors and indoors. Although, some GNSS systems like United States' GPS and Russian GLONASS are fully operated, modernization of these systems is still on-going. The European Unions' Galileo and the Chinese COMPASS GNSS systems are expected to be in full service in global navigation modes by 2020. Some other regional navigation systems such as the Japanese QZSS and the Indian IRNSS are being under development and expected to be completed and implemented through the coming few years. This study aims to investigate and report the current status of GNSS systems and to focus on its applications and use in the Gaza Strip. A comparative analytical case study of getting positions in Gaza City and based on GPS, GLONASSS and GPS + GLONASS multifrequency data is performed. It shows that about 56 % improvements in the positioning accuracy is obtained when considering GPS + GLONASS data instead of GPS data alone and 69 % compared with that of using GLONASS data alone.

Utilizing the Internet of Things in the Public Sector

This study investigated the utility of the internet of things in the public sector and the factors influencing the satisfaction of its users. The study followed two directions: The first investigated managers’ perceptions and their satisfaction with using sensors for tracking vehicles. The second direction investigated drivers’ satisfaction with the system used. Results collected from 20 interviews conducted with managers revealed that cost reduction and more control over drivers’ behaviors are the contributions expected from the system. They reported the dissatisfaction of drivers based on violation of their privacy, inequity of implementation, and the low awareness of its utility. Surveys collected from drivers supported the role of trust and privacy but failed to support the role of usefulness. The qualitative and quantitative nature of this research revealed valuable insights and concluded to important recommendations and future work

Application of tracking systems in the organization

55 s., 42 s. příl. :obr., tab., grafy +CD ROMBakalářská práce se zabývá uplatněním sledovacích systémů a jejich využitím v organizaci. Práce se zaměřuje výhradně na sledovací systémy služebních vozů využívané ve správě firemních vozových parků. Teoretická část práce se zabývá hodnocením současného stavu problematiky sledovacích systémů, popisuje systémy, které jsou v současnosti dostupné na českém trhu, shrnuje jejich možnosti a funkcionalitu a dále porovnává jednotlivá konkrétní řešení jak z hlediska funkcionality, tak z hlediska jejich ceny. V praktické části práce je popsána případová studie týkající se průběhu pořízení sledovacího systému konkrétní organizací od sepsání seznamu požadavků na systém až po výběr nejvhodnějšího řešení. V závěru práce je potom vyhodnocen přínos využití sledovacího systému ke správě vozového parku
