In my thesis I will represent the outdoor positioning methods and their main application possibilities that are used at nowadays.

The reason I chose this subject is that over the past few years more and more people are using location-based services through the softwares and applications on mobile phones. So it can be interesting to find out, what kind of positioning methods exist, define their main characteristics, advantages and disadvantages, and finally get an overview about the most important location-based services.

After this short brief in my thesis I present the most remarkable positioning systems. First the positioning system based on satellite will be discussed, and then the location possibilities using cellular mobile systems will be introduced, followed by methods based on Wi-Fi technology at the end of that section.

Then I present the Android-based mobile application that I created during the Project Laboratory course and in which I implemented many kind of positioning functions.

In the following chapter the measurements, what were taken with my mobile app, will be analyzed bringing several aspects into consideration. Based on the analysis I will evaluate the realized positioning methods consider the accuracy and calculating time.

Least I present some location-based services, which use the introduced positioning methods.
