Turkey's National Permanent GNSS Network-Active (TUSAGA-Active) that has been started to use since 2009 is currently the most widely used geodetic infrastructure element in point positioning in Turkey. In addition to this network operating with the network RTK principle, there are also local Continuously Operating Reference Stations (CORS) networks in our country, which are mainly operated by local governments and a small number of private sector organizations. These networks, which are used nationally and locally, are used effectively in scientific studies as well as in basic engineering works. Integration of local networks in the axis of standards to be defined with the national TUSAGA-Active network is an important issue that should be on the agenda of our country's geodesy community. In this study, CORS networks established at national and local levels in different countries, and examples of the developed standards are given, the current situation in Turkey and contribution of local networks to the scientific studies are discussed. The studies conducted for the comparison of national and local CORS networks were examined, emphasizing the importance of distance between stations in determining the positioning. In this context, the contribution of local networks to the national network has been demonstrated. In this framework, it has been evaluated that shortening the baseline lengths as a result of integration and thus increasing the point density may contribute positively to the network solution quality. However, in order to achieve this development, it is recommended that the development of standards for the design and operation of CORS networks established locally in our country should be addressed with priority.
