The report deals with creating applications for Pocket PC, designed to aid with terrain mapping process. Topic falls within the field of geographic information systems (GIS), so the text begins with an analysis of related topics such as GIS itself, processed data characteristics or global positioning systems (GPS). Available handheld platforms are discussed and based on analysis of existing commercial application, the requirements on developed program are set. Description of application architecture and some implementation details follow. The conclusion is devoted to testing functionality by mapping the real geospatial object.

This document describes a device capable to determine geographical position thanks to its GNSS module and measure the change of movement with the help of an accelerometer and gyroscope. Outputs of these integrated circuits are combined, data are processed and fused thanks to a numerical integration and mathematical filters. Results are stored on a memory card. The whole development is described from a concept, through the making of the device and software algorithms to the testing of its functions.

This master’s thesis is the design of the system of the differential GPS, creation of the software for basic wireless communication between 2 GPS receivers, and practical tests of the designed system. Parameters and characteristics of system were determined and they should inform us better about the appropriateness of the designed system for navigation of a mobile robot in outside conditions.

The thesis contains complete design of complex system for acquisition of data from bus of a vehicle. It resolves problems of connection of a new node to CAN bus of a vehicle, communication protocol NMEA 0183 of GPS receivers, logging of caught CAN frames into database system MySQL, and proposes algorithms of application for operation of the system. It includes also process of complete installation based on established concept and test results of the system in real situations.

The aim of my dissertation work was to create an application for pocket PC with operating system Windows Mobile and touch screen, an application that would enable to position the current location of the pocket PC based on the GPS data, on distance measurement between two and more points of which the location is obtained from GPS, and on measurement of territory surface defined by certain number of points obtained from the GPS. The application also enables to display the characteristics of the received GPS signal, information about the number of visible satellites and also information about maximum deviation from positioning. In order to increase the accuracy of the positioning, an averaging function has been implemented. As additional function, a possibility of route location has been created. It measures the passed distance and records some other route characteristics. The application has been successfully tested on pocket PC E-ten M600+ and GPS receiver Navilock but it has been designed with general-purpose and should be compatible with all devices working with operating system Windows Mobile and touch screen. The text section of my dissertation work describes the positioning principle on the basis of satellites with known position, deals with the accuracy of these systems and describes few possibilities how to increase their accuracy. It also discusses the NMEA 0183 Protocol that is used by the majority of GPS modules for communication. The text section also describes several mathematic and cartographic calculations needed for realization of the application. In the end of the text section there is a detailed description of the created application.

The objective of the diploma thesis is to design a device for positioning of mobile devices using GPS satellites. When coordinates are acquired they can be sent via the GSM network to a user's cell phone or to an SQL server. A web interface has been designed to access the stored data and to show the current device position and the history. This position datalogging system can be used for monitoring vehicles as well as a security system for cars.

FM transmitter APRS of telemetric data is device able to measure telemetric values from its ambient. It is able to send this data to user on earth by radio frequency channel. This device can create data frames, with proper formatting allowing sending data. It operates in 435 MHz band, uses FSK and AFSK modulation. This work describes basic information of used protocols, electronic connection of this transmitter and software equipment.

Theoretical information about different satellite navigation systems used for determination of position. Special attention is attended to system GPS. There are consulted main principles of the GPS and some error sources. Application of differential GPS for minimization of these errors is discussed. Next part is about examples of basic principles for measuring earth magnetic field. Last chaps are about practical realization of mentioned DGPS, which is applied for outdoor mobile robot navigation. There is described hardware structure, software utilities and application of an aided tool for GPS - electronic compass. Some practical measurements and results are presented.

There is suggestion of obtaining exact position in this work, based on GPS and GSM modules controlled by PIC microcontroller. Layout of this work is electronic schematic, PCB footprint and theoretical analysis of used modules. The practical part of work is also dealing with software for both microprocessor and web interface. The function prototype will be created and tested in next phases of this project.

The main theme of this masters's thesis is to design and make a miniature universal tracking device. This device is primarily for tracking asset, pets or people. For detecting the position data is used GPS technology. Data transmission is carried out via the GSM network. The device is technically solved and realized with respect to miniature size, high battery life and with regard to resistance against water, dust and impact damage. It is selected unique design, suitable for hermeticaly closure of the entire facility. Due to hermetic closure there is any buttons, any connectors and the battery charging is wireless.
