| Popis: | Erdoǧan, Hediye ( Aksaray, Yazar ) In this study, the main factors affecting the velocities of Global Navigation Satellite System (GNSS) stations were investigated. In order to improve the accuracy of GNSS station velocities, the optimal number of campaigns, the total time period between the individual campaigns, and session observation time were investigated using 14 campaigns of GNSS data obtained from eight Continuously Operating Reference Stations (CORS-TR). In addition, multiple regression analysis was performed to statistically test the effect of the determined parameters. The determined regression parameters enable to estimate the accuracy of GNSS station velocity that could be obtained when the number of campaigns, observation time and the total time period between the first and the last campaign are given. As a result, it was determined that the relationship between the accuracy of GNSS station velocity values and the time between the campaigns was t(observation time), and the inverse ratio was approximately two times. |
