In Global Navigation Satellite Systems (GNSS)- based positioning applications, the efficiency and use of Precise Point Positioning (PPP) technique have gradually increased compared to the relative positioning technique. However, in many studies performed on different platforms in static and kinematic modes, the largest disadvantage for the traditional standard PPP method is the long convergence time for carrier phase observations. Therefore, observation duration in studies that are based on the PPP method in static and kinematic modes is often kept long. In this study, considering the positioning accuracy obtained depending on observation duration and ambiguity resolution in PPP, the performance of kinematic GPS+GLONASS observations obtained by repeated and short pedestrian walks were compared with relative positioning solutions for short, medium and long bases. For comparison, the internet-based GNSS data processing service namely CSRS-PPP, which is widely used worldwide and uses new algorithmic approaches to shorten the convergence time for carrier-phase observations, was preferred. The results clearly demonstrate that the PPP method for short-term kinematic observations can be used effectively for obtaining high-accurate positioning information, which is also equivalent to relative solutions.
