My thesis is about the development of a tracker which is able to determine the current position and speed, processes these data in real time and record them. The comfortably handheld device can be used in vehicles or while hiking. The built-in LCD display shows the current time, coordinates, speed or heading. The route traveled is saved to an SD card according to time intervals or as distance. The user can easily switch between the two modes of collection. The data will be saved in a format that can be easily visualized by using a map viewer software.

The thesis begins with the presentation of the GPS system, where we will learn about the principles of positioning. The first phase of the design, I created a block diagram of the system according to the requirements and described the selection process of the necessary parts. A microcontroller was needed to control a GPS receiver for positioning, a display for showing the data, and an SD card for recording. Creation process of the schematic, the printed circuit board design, the revision of the device, and software development are described on the next sections.

At the end of the thesis there is a summary of the work carried out and at last we will discuss further development of the device.
