Trimble has been selected by Istanbul Kültür Üniversitesi (IKU) to supply 150 Trimble NetR5 reference stations, 150 Trimble Zephyr Geodetic 2 antennas and Trimble VRS technology, to establish a nationwide Global Navigation Satellite System (GNSS) infrastructure network for the country of Turkey.
The Trimble VRS network will provide a geospatial infrastructure for surveying, engineering and Geographic Information System (GIS) professionals that enables high accuracy real-time kinematic (RTK) GNSS positioning, without the need of separate base stations or software, significantly increasing efficiency and productivity.
In addition to supplying the technology, Trimble is providing a turnkey solution that includes building the GNSS network, known as CORS-TR (Continuous Operating Reference Station-Turkey or TUSAGA AKTIF), as well as installing the network’s control centres.
The GNSS network will be operated by the Turkish General Directorate of Land Registry and Cadastre (TKGM) and General Command of Mapping (GCM), and financially supported by The Scientific and Technological Research Council of Turkey (TÜBİTAK), the country's important agency for management, funding and research. The main control centre will be managed by the TKGM backed by the one in GCM.
“The national CORS-TR project provides new opportunities for national mapping and the use of information technologies in Turkey,” said Kamil Eren, of the Faculty of Engineering & Architecture - department of civil engineering, of Istanbul Kultur University.
“The Trimble VRS network will also make it easier to use GNSS technology for a variety of high-tech applications.”
One among the GNSS networks in the world, the CORS-TR system will supply centimetre-level RTK GNSS data for a range of positioning applications including geodetic and cadastral surveying, road and bridge construction, earthquake and tectonic plate movement monitoring and analysis, and scientific research, as well as other high-accuracy positioning applications.
Turkey also plans to use the network to improve and maintain the vertical and horizontal quality control network as well as calculate the nationwide datum transformation parameters.
The nationwide Turkey VRS network follows more than 150 Trimble infrastructure installations networks throughout the world including: China, Germany, Poland, Austria, Switzerland, U.S., Singapore, Portugal, Canada, Norway, Sweden, Finland, Denmark, Belgium, France, Spain, Italy, United Kingdom, Netherlands, Serbia, Slovenia, Slovakia, New Caledonia, Australia, Malaysia, Taiwan, South Korea, Southern Poland and Japan.
