Trimble Snares Big Turkey GNSS Network Contract

Turkey's Istanbul Kultur University has selected Trimble to supply GNSS equipment and establish a 150-station, nationwide GNSS infrastructure network

Under the terms of the contract, Trimble will supply 150 Trimble NetR5 Reference Stations, 150 Trimble Zephyr Geodetic 2 Antennas, and Trimble VRS (Virtual Reference Station) technology that will be used to create 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.

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 centers. The GNSS network will be operated by the Turkish General Directorate of Land Registry and Cadastre and the General Command of Mapping, with financial support from the Scientific and Technological Research Council of Turkey.

One of the largest GNSS networks in the world, the Turkish CORS-TR system will supply centimeter-level RTK GNSS data for a variety 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.

NetR5 dual-frequency receivers can performance code and carrier phase tracking of both GPS and GLONASS signals.
