In this paper, for small-scale surveying applications, investigation of appropriate methods among classical RTK, net-RTK which provides Virtual Reference Station (VRS), and Fl chen-Korrektur Parameter (FKP) corrections were performed. A test network consisting of 56 stations has been established in Istanbul. Measurements were carried out using the above methods. Five separate tests were applied on the coordinates obtained by the methods. The results showed that the methods from the most accurate to the least accurate one were classical RTK, Net-RTK-VRS and Net-RTK-FKP. In general, horizontal components were found to be two times better than vertical components ranging from 1 mm to approximately 5 cm.
