1	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.

3	Webbaserad visning av positioner på karta / Web based presentation of positions on a map Engström, Martin January 2010 (has links) Today there are a big need for a system that delivers overview of all available units for different municipalities and shipping- and security companies due to the increasing requirements for efficiency. The purpose with this graduation thesis is to find out which systems that is suitable to use while developing cost-effective software for positioning and to produce a prototype for such solution. This assignment has been done at the request of PocketMobile Communications AB. PocketMobile is a company that are specialized on delivering modern mobile software solutions and systems to companies with their own vehicle fleet or mobile workers. This master thesis can be split into two separate parts, the theoretic- and the practical part. The theoretic part includes producing a number of functional requirements in cooperation with PocketMobile and comparing the available systems against the function requirements. The practical part deal with the development of a prototype that demonstrates the software recommended. The development tools that best matched the functionality requirements when the selection was made in May 2007 were Map24 and OpenLayers. The system that was selected to use while developing the prototype was Map24, because this product matches all of the requirements and it is also suited for professional usage regarding support, scalability and reliability. Map24 also have some advanced functions like ability to route plan for example. The prototype that has been developed is web based and the graphic design is similar to Google Maps.
