In recent years, Global Navigation Satellite Systems (GNSS) have gained great importance in terms of the benefi ts it provides such as precise geodetic point positioning, determining crustal deformations, navigation, vehicle monitoring systems and meteorological applications etc. As in Turkey, for this purpose, each country has set up its own GNSS station networks like Turkish National Permanent RTK Network analyzed precise station coordinates and velocities together with the International GNSS Service, Turkish National Fundamental GPS Network and Turkish National Permanent GNSS Network (TNPGN) stations not only are utilized as precise positioning but also GNSS meteorology studies so total number of stations are increased. This work is related to the reactivated of the TRAB IGS station which was established in Karadeniz Technical University, Department of Geomatics Engineering. Within the COST ES1206 Action (GNSS4SWEC) KTU analysis center was established and Trop-NET system developed by Geodetic Observatory Pecny (GOP, RIGTC) in order to troposphere monitoring. The project titled “Using Regional GNSS Networks to Strengthen Severe Weather Prediction” was accepted to the scientifi c and technological research council of Turkey (TUBITAK). With this project, we will design 2 new constructed GNSS reference station network. Using observation data of network, we will compare water vapor distribution derived by GNSS Meteorology and GNSS Tomography. At this time, KTU AC was accepted as E-GVAP Analysis Centre in December 2016. KTU reference station is aimed to be a member of the EUREF network with these studies.

Celem pracy jest pokazanie możliwości kontroli punktów geodezyjnych niedostępnych do bezpośredniego pomiaru technologią GPS RTK oraz możliwości odszukania punktów granicznych, nad którymi nie można bezpośrednio postawić tyczki z odbiornikiem GPS. Opisano kilka przykładów takich punktów, potrzeby ich pomiaru kontrolnego oraz przeprowadzono testy na wybranym obiekcie testowym. Jako metodę pośredniego pomiaru wykorzystano metodę wcięć liniowych. Odniesiono się także do innych metod pomiaru pośredniego punktów niedostępnych.

The main goal of this paper is to show the possibility to inspect geodetic points which are unavailable for direct RTK survey along with the possibility to find a border point when one can not place a measuring pole over it. Few types of such points are described with the reasons to inspect them. In addition some experimental examples are provided. The traverse method was used as a method of indirect survey. Other methods are also described.
