Besides the Global Positioning System (GPS) and Globalnaya Navigatsionnaya SputnikovayaSistema (GLONASS), two additional global navigation satellite systems (GNSS) have reached full operational capability in recent years. The European Union, along with the European Space Agency, introduced the Galileo positioning system. China is developingthe BeiDou system. To fully utilize the capabilities of the new systems, dedicated precise models and corrections are necessary. An example of such corrections can be antenna phase center corrections (PCC). In the case of Galileo, access to phase center corrections may be challenging. This is because a lot of GNSS antenna types still have no corrections directly dedicated to Galileo signals. In such a case, corrections created based on GPS signals are recommended. The study compared the positions of stations, determined based on Galileo-only observations using type-mean and individual PCC models obtained from field and anechoic chamber calibration. Additionally, calculations were performed using elevation-only PCC based on the type-mean model. It was demonstrated that position shifts resulting from the use of individual PCC derived from an out-door calibration instead of individual calibration in an anechoic chamber (dedicated PCC set for Galileo signals) can reach up to 5 mm in the vertical component, whilefor horizontal components, these shifts are generally less than 2 mm.
