Definition of behavior of GNSS stations in Kirikkale and surrounding

In this study, linear changes in the Turkey Real Time National Permanent GNSS Network (TUSAGA-Active/CORS-TR) stations located around Kırıkkale have been examined in cause-effect relationship and plaque speed values of the region have been obtained. For this purpose; daily coordinates of [TNGPN-Active (CORS-TR) stations of] NRK (Ankara), BOG1 (Boğazlıyan), CANK (Çankırı), CMLD (Çamlıdere), CORU (Çorum), HYMN (Haymana), KIRS (Kırşehir), KKAL (Kırıkkale), SUNL (Sungurlu) and YOZ1 (Yozgat) stations between the years of 2015-2018 have been obtained from/using the academic software GAMIT-GLOBK. Linear attitudes of the stations have been calculated by applying a linear function to the time series obtained before. Result of this analysis, horizontal linear movements for CANK, CMLD and HTMN stations are at an average of 20.16 mm/year in southwest direction and for other stations in northwest direction at an average of 19.19 mm/year. In time series, it is seen that "up coordinates" of the linear movements of BOG1 and HYMN stations are in (-) direction, while movements of ANRK, CANK, CMLD, CORU, KIRS, KKAL, SUNL and YOZ1 stations are in (+) direction. It is seen that linear movements obtained from this study are in accordance with Kırıkkale region's plaque speed values where these stations are located. Correlation coefficients were calculated in the time series of GNSS stations north, east and up coordinates. The obtained correlation coefficients were correlated with the station velocity values.
