The ”GPS Toolkit” (GPSTk) project is an advanced GNSS Open Source Software (GOSS) suite initiated by the Applied Research Laboratories of the University of Texas (ARL:UT), aiming to provide a world class GNSS library computing suite to the satellite navigation community. The objective of this work is to show how the GPSTk suite may be used to rapidly and easily develop, implement and test advanced GNSS data processing applications in a flexible way. The main characteristics and modules of the GPSTk are also presented, as well as the current trends in its development. Results from the GNSS data processing carried out with the examples introduced in this work are shown, as well as a brief comparison with an established GPS software package such as BRUS.
