Özet

Network Real-time kinematic mode survey technology shows really an efficient and fast improvement within today’s technological developments. Permanent reference stations for Global Navigation Satellite System (GNSS) have for a long time been used for positioning of rovers in RTK (Real-Time Kinematic) mode. In this article, we examine the performance and use of Continuously Operating Reference Station (CORS-Network RTK) as an extension of RTK technology-based data acquisition systems near/under tree canopy. As a general rule, a clear view of the sky is preferred when using RTK for determining location. Eight permanent reference stations belonging to the ISKI (Istanbul Water and Sewerage Administration) in Istanbul, Turkey were used for the test measurements. This paper presents the results of İSKİ (Istanbul Water and Sewerage Administration) CORS satellite measurements made using Networked Transport of Radio Technical Commission for Maritime Services via Internet Protocol (NTRIP) data transmission. As a result of measurements taken at 17 measurement points in the obstructed and unobstructed environments, the accuracies obtained at the points with numerous covers in the form of tree branches and leaves ranged from several centimetres which is characteristic for GPS/GLONASS measurements taken under conditions of limited availability of satellites.
