Abstract
The goal of this work is to present a new method of position detection for autonomous systems. The method suggests usage of classical triangulation technique for which the main input, the angle value, is measured using a new approach, which implies measurement of the phase difference between two wireless receivers physically placed in a specific manner. The mutual placement of the receivers is defined by the selected frequency of the transmitted signal, namely its wavelength. The thesis describes the method itself, its simulated model and some practical issues and limitations.

Student presents the results and his approach in solving the bachelor thesis. He answers the questions of his supervisor, his opponent and the comitee:
Will the amplifiers and filters be placed directly at the antennas? What type of amplifier are you considering and what filter approximation in terms of phase stability?
Student answers the question.
What if the transmitter is very close to one of the antennas and far from the others? Over what range of distances will the proposed system work?
Student answers the question.
What is the expected time constant for determining the transmitter position? Will real-time tracking be possible?
Student answers the question. After, he discusses the close field of the device with Ing. Zbyněk Lukeš, Ph.D.
