N2 - Positioning with satellites increasing its importance day by day in paralel with the technological developments. Nowadays, GPS comes to mind first, as a global positioning system. It is the most developed and prefered satellite system. With launched new satellites, GLONASS can be used alone as well as together with GPS. With recent revitalization of GLONASS, high precision GPS/GLONASS receivers have been produced. By considering these developments, it becomes worthwhile to investigate the usability of GLONASS on global positioning. In this study, a network of 6 IGS tracking stations equipped with GPS/GLONASS receivers, was formed, besides 24 hourly observations processes were performed by taking into consideration 6 and 12 hourly observations to examine the influence of short observation duration. Processes were performed separately by using GPS, GLONASS and GPS/GLONASS observations. Bernese 5.0 academic analysis software were used in all data processing. Results showed that GLONASS observations can be used alone, also together with GPS on global positioning.
