Abstract:	In this paper, the authors present a software tool which is able to automatically read RINEX (Receiver Independent EXchange Format [1]) files (navigation and observation files) and performs Global Navigation Satellite System (GNSS) positioning using pseudorange and carrier phase measurements. Data are served by the Instituto Cartografico de Cataluña (ICC, Cartographic Institute of Catalonia [2]) and correspond to a network of thirteen receivers distributed along the Catalonia (North East Spain, Europe). The software tool performs GNSS differential positioning using code and carrier phase measurements of two stations. LAMBDA (Least squares AMbiguity Decorrelation Adjustment, [3], [4]) method has been used to solve the inherent integer ambiguity when carrier phase measurements are used. Statistical studies of the error in positioning are performed for different baseline distance between receivers and different type of measurements used. The results assess how the error in positioning increases with the baseline distance between the receivers and the benefits of using carrier phase measurements to achieve high precision positioning.
