Mayor Greg Nickels officially launched the Puget Reference Station Network, a regional GPS network, which covers 1,600 square miles.

Mayor Greg Nickels officially launched the Puget Reference Station Network (PRSN), a regional Global Positioning System (GPS) network, which covers 1,600 square miles and will provide significant benefits for Seattle and the surrounding regions.

Using technology developed by Trimble, the PRSN will supply centimeter-level, real-time GPS data to government agencies, emergency managers, research institutions, scientific agencies, and private surveying and mapping professionals for a variety of applications including surveying, field inventory, construction, disaster response and scientific research.

The 10-station network is an extension of a four-year pilot project undertaken by Seattle Public Utilities (SPU); the pilot network was a four-station Trimble VRSÔ (Virtual Reference Station) network. The VRS enables users to take precise readings over much greater distances with fewer reference stations. Due to the scalable nature of the technology, the network can continue to grow as needs and coverage area increases. There are plans to expand the network to 32 stations covering 12,000 square miles throughout western Washington and then to 80 stations statewide.

The City of Seattle has partnered with the City of Renton; Kitsap Public Utility District (PUD); Washington Department of Transportation (WSDOT); Snohomish, King, Pierce, Thurston, Island and Skagit Counties; University of Washington (UW) and Central Washington University (CWU); the National Oceanic Atmospheric Administration (NOAA); and the National Geodetic Survey (NGS).
