Özet:    Web-Based GNSS (Global Navigation Satellite System) processing services provide the user to obtain precise coordinates. These services are divided into two that provide a relative and absolute positioning approach. In this study, static processing performances of OPUS (Online Positioning User Service)  and AUSPOS (Online GPS Processing Service) GPS services  were tested by considering the long (24 h) and short (2 h) observation periods. For this purpose 8 IGS stations, located in different geographical regions in the world were used. In order to test the accuracy of the OPUS and AUSPOS, their results were given in a comparative approach to the measurement epoch coordinates of the stations in ITRF 2008 reference system. The obtained results show that these services can be used for positioning easily and economically with accuracy, which can be sufficient for high accuracy required studies such as monitoring crustal movements, structural health monitoring using 24 hourly data with a single receiver and civil applications such as cadastral applications where 2 hourly data may be sufficient.
