The WSRN (Washington State Reference Network) is a regional cooperative of GPS reference stations and data that enables cost-saving solutions for public and private sectors in the fields of surveying mapping, and other high accuracy location technology needs. GPS Data Files from a network of Continuously Operating Reference Stations (CORS) are available for download to all, with real-time services available through partnerships, memberships, and subscriptions. This website provides a rich content of services, support for users, system status and monitoring reports, solutions and tips for users, and an open forum for users and other parties interested in real-time GPS. The WSRN is an integral part of the modernization of the Spatial Reference System for Washington State as the “active control” component; working with state and federal agencies, scientific and academic communities, as well as the geospatial communities of surrounding states and provinces.
