After the late 1990s, GNSS/GPS network RTK technology has become the preferred technique in the world, today widely used in various applications such as monitoring, early warning systems, and mapping and engineering applications. By the end of 2008, the CORS-TR network was being used for engineering applications to determine 3D positions across the whole of Turkey. On the other hand, single base RTK stations are being operated in Turkey. The YLDZ is one of these types of stations. It was established at the Yildiz Technical University by the Department of Geomatic Engineering in 2012. In this paper, the performance of the YLDZ station is examined by use of measurements in 5 Istanbul GPS Triangulation Network (IGNA) benchmark points, with five repeatability measurements up to 50 km from the station. The CORS-TR network RTK solution is used at the same points, and the results are compared. The measured coordinates produced by the two RTK solutions are compared with the IGNA point coordinates. Satellite geometry, initialisation time and the standard deviation of repeatability are also determined. The differences between measured and known coordinates are calculated as 1-2 cm horizontally and close to 3 cm vertically using the YLDZ single base RTK method. Keywords: RTK GNSS, CORS, Single Base RTK Despues de la decada de los 90, el Sistema Global de Navegacion por satelite/Sistema de Posicionamiento Global (GNSS/GPS, en ingles), basado en tecnologia de Navegacion Cinetica Satelital en Tiempo Real (RTK, del ingles Real Time Kinematic) se convirtio en la tecnica preferida en el mundo y que todavia se utiliza en varias aplicaciones como el monitoreo, sistemas de alerta temprana y mapeo e ingenieria de aplicativos. Para finales de 2008, los aplicativos de ingenieria utilizan la red de Estaciones de Referencia de Funcionamiento Continuo (CORS-TR, un proyecto establecido en Turquia) para determinar posiciones en tres dimensiones a lo largo del territorio turco. Por otro lado, las estaciones RTK de una sola base han funcionado en Turquia. La YLDZ es una estacion de este tipo que fue establecida en la Universidad Tecnica de Yildiz por el departamento de Ingenieria Geomatica en 2012. En este trabajo se examina el desempeno de la estacion YLDZ a traves de la medicion de cinco puntos de referencia del Sistema de Triangulacion GPS de Estambul (IGNA, en ingles) con cinco mediciones repetitivas a mas de 50 km de la estacion. Similares medidas RTK se hicieron con la red CORS-T
