In 2005, the Utah Legislature, recognizing the need to support highly accurate GPS applications for surveying, engineering, construction, and GIS data
collection, passed into law UCA 63F-1-509 to fund the initial build-out of a real time GPS base station network.
• Created the Statewide Global Positioning Reference Network to improve the quality of geographic information system data and the productivity, efficiency, and cost-effectiveness of government services;
• Required the Automated Geographic Reference Center (AGRC), within DTS, to administer the network; and,
• Provided the first (FY05, $375,000) of two initial years of funding for hardware, software, construction materials, and labor to implement,
expand, and maintain the network.
The Utah Reference Network (TURN) GPS is now a statewide network of 70 survey grade GPS receivers permanently located across Utah. The network is used by 350 paying and partnering subscribers including major utilities, UDOT and its contractors, public and private land surveyors, and heavy machinery (tractors, graders) control users in the construction and agricultural sectors.
The network is highly dependent on an active partnership of cities, counties and state agencies for its success and consists of equipment, internet connections, and facilities furnished by partners and a central ‘solution server’ maintained by AGRC in the DTS data center.
AGRC has a one-time funding need for maintenance for the TURN GPS Network.
• The network currently runs on software developed in 2002 and is limited to a 32 bit server platform.
• The 32 bit system has reached its processing threshold for network expansion and concurrent user growth.
• Approximately 35 of the 70 GPS network receivers are older models, unable to take advantage of GPS signals from new satellite deployments made by the international community.
