The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Global Positioning in Harsh EnvironmentsResch, Bernd, Romirer-Maierhofer, Peter January 2005 (has links)
As global location systems offer only restricted availability, they are not suitable for a world- wide tracking application without extensions. This thesis contains a goods-tracking solution, which can be considered globally working in contrast to formerly developed technologies. For the creation of an innovative approach, an evaluation of the previous efforts has to be made. As a result of this assessment, a newly developed solution is presented in this thesis that uses the Global Positioning System (GPS) in connection with the database correlation method involving Global System for Mobile Communications (GSM) fingerprints. The database entries are generated automatically by measuring numerous GSM parameters such as Cell Identity and signal strength involving handsets of several different providers and the real reference position obtained via a high sensitivity GPS receiver.

Advanced Traffic Service / Avancerad TrafiktjänstLöfås, Peter January 2005 (has links)
More and more travellers use navigation-aid software to find the way while driving. Most of todays systems use static maps with little or no information at all about currently yeilding roads conditions and disturbances in the network. It is desirable for such services in the future to include information about road works, accidents, surface conditions and other types of events that affects what route is currently the best. It is also desirable to notify users about changes in the prerequisites of the chosen route after they have started their trip. This thesis investigates methods to include dynamic traffic information in route calculations and notifying users when the characteristics change for their chosen route. The thesis utilizes dynamic traffic information from The Swedish Road Agencys (Vägverket) central database for traffic information, TRISS and calculates affected clients with help of positioning through the GSM network.

Real Time Positioning; Construction and implementation of a GPS-Communicator. / Realtidspositionering; Utveckling av en GPS-kommunikator.Darnell, Christian, Wilczoch, Christian January 2002 (has links)
The first half of the Masters thesis is the result of a survey made on the behalf of the Swedish company KORDAB International AB. The survey includes an overview of different positioning systems and some wireless communication techniques available on the market today. Positioning systems discussed are GPS, DGPS, AGPS and GSM positioning. Mobile Internet connections through mobile phones and communication through radio modems are mentioned and described as examples of wireless communication techniques. Examples of techniques described are HSCSD, GPRS, UMTS and MOBITEX. KORDAB is in the starting blocks to implement a real time positioning feature into their own technical information system GEOSECMA. This survey will give them a base which will help them to decide on which system to use for this feature. The second half of the thesis includes parts concerning a prototype made to exemplify how KORDAB could implement the real time positioning feature into GEOSECMA. The NMEA 0183 protocol, reference systems and transformation are described to give the necessary background knowledge for the construction and functionality of the prototype. The prototype is a GPS-communicator made as an interface between a GPS-receiver and GEOSECMA and its functionality is also described in this second half of the thesis. Feasible applications are also discussed to show the possibilities real time positioning gives. One application discussed is “Zoom and Auto highlighting”. This application is designed to help user of GEOSECMA to zoom in the map and highlighting the nearest object at current location.
