This chapter focuses on methods and techniques of positioning, based on the highly accurate and precise Global Navigation Satellite System (GNSS), which are available at a relatively low price. In this context, a comparison of different positioning methods provided by the free and open source software (FOSS) package called RTKLIB is given. Other aspects related to price reduction are also considered, including availability and selection of hardware (receiver, antenna, etc.) and market growth. The theoretical comparison of positioning methods is illustrated with their in-situ evaluation using a low-cost GNSS receiver. The evaluated receiver (i.e., u blox LEA-6T) provides different types of information including raw carrier phase measurements, therefore it allows us to obtain a very high precision of positioning by means of relative positioning algorithms. As the source of reference data for relative positioning, the services from the ASG-EUPOS system were used. ASG-EUPOS is a Polish GNSS augmentation system consisting of a network of GNSS base stations. It provides real-time corrections as well as post processing services for the entire territory of Poland.
