Location tagging is used to measure spatial data. The amount of data is increasing with technology accessibility and it is often publicly available. Location-tagged measurements help us understand the phenomena happening around us.
The most common way of determining location on Earth nowadays are global navigation satellite systems (GNSS). Recent advances in technology made it possible for receivers to be very small, light and inexpensive, as well as achieve accuracies in the centimetre range.
An unmanned aerial vehicle (UAV) can be equipped with such receivers and different sensors to take location-tagged spatial measurements. The data can then be processed and shown on different charts and maps.
The thesis addresses the development process and evaluation of an unmanned aerial platform for capturing location-tagged measurements. In the beginning, the basics of coordinate systems and location determining on Earth are presented. The second part explains the basics of UAVs and the process of building one for capturing location-tagged measurements. The third part describes the flight testing process and evaluates the height and position measurement accuracy using GNSS and other methods. The last part presents some test measurements of the radiation patterns of different antennas.
