Investigating Precision of Network Based RTK Techniques: Baseline Length Is Concerned

( Volume 5 Issue 1,July 2017 ) OPEN ACCESS

Sermet Ogutcu, Ibrahim Kalaycl


This paper investigates the precision of commonly used Network Based Real Time Kinematic (NRTK) techniques namely, VRS, FKP, MAC. Surveys were conducted within the Turkish Tusaga-Aktif CORS network. Two CORS stations were chosen whose interstation distance is approximately 100km. Within this baseline, eight test points were chosen to create the incremental baseline length as follows, 5, 20, 40, 50km between the CORS stations and the rover. Special apparatus was improvised to collect the NRTK data simultaneously for each technique from three high-grade GNSS receivers. Approximately 3000 epoch with two second interval was obtained for each test point and NRTK technique. Results show that horizontal and vertical precision depends on the baseline length between the rover and the CORS station which broadcasting the network correction for the rover.
