Abstract: Today, point coordinates are determined by two different methods which are relative positioning and absolute positioning, with GNSS. Although the relative positioning technique is preferred in terms of providing high position accuracy, post-processing is seen as difficult by the users due to the processing load. Web-based relative positioning techniques have been developed to overcome the difficulty of the post-processing method. In this study, the success of AUSPOS and OPUS which are web-based relative positioning methods was investigated in different atmospheric storms (Kp, Dst and F10.7) and short session durations (2 h). In this context, the 7th day of year 2014 and the 173rd and 174th days of year 2015, when there were different atmospheric storms were selected as study days and 6 of CORS-TR stations were selected test points. In addition, the coordinates of the measurement epoch of the test points were determined with Bernese v5.2 Scientific GNSS software. These coordinates were taken as true quantity values and compared with the coordinates obtained from AUSPOS and OPUS. As a result of the comparison, the best root mean square errors (rmse) were obtained on the 7th day of 2014 with AUSPOS. When the coordinates-based rmse were compared, it was concluded that AUSPOS slightly gave better results, but the 3D rmse obtained from both software were not statistically different from each other.
