LEA-6T GPS receiver is an integrated navigational GPS module created by uBlox. Unlike most receivers of this type, not only does it send a position but also transmits raw observation data (carrier phase, pseudorange and Doppler). The main purpose of this study is to examine the usefulness of these findings for precise positioning, which would allow to use the test receiver in satellite geodesy. The evaluation platform made at the Institute of Geodesy served as a tool which enabled to record and store data sent from LEA-6T receiver. The recorded data were converted into a universal format for the raw observation data (RINEX 2.11). Then, the positioning quality and signal tests were investigated through a thorough analysis of the recorded data with the help of a surveying and navigation antenna. The test results are shown in the following study.

Keywords: Low – cost receiver; LEA-6T; GPS observation.
