Nowadays we can see more and more electronic devices that help us with orientation or tracking particular tools or people. Although positioning systems like this are in use for quite a long time, the need to know more precisely the exact distances increases day by day.

Smart places (warehouses, homes, etc.) are more frequent, so indoor positioning gets more attention on the fields of research and development sections. There are a lot of already working solutions with which we can measure accuracy within about 50 centimeters to 1 meter but there are other technologies, that can range even better than that.

In my thesis i’m working with a technology like this. With UWB based systems we can reach precision within centimeters but we have to adjust the devices carefully, to get the best results. In this paper you can read about the basics of this technology and the real time location systems that can be built using this technology. After that I’ll get to the parameters that has a great effect on the accuracy of measurements and I show an algorithm with which precision can be improved.

I validate the effectiveness of the algorithm with measurements, and evaluate the results, then I examine further development potentials.
