Abstract: Panel presentation and Q&A session by the IA, MN, and WI DOT. Topics will include benefits of the Continuously Operating Reference Station/Real Time Reference Network Global Navigation Satellite System (CORS/RTRN GNSS) network to the citizens of the states, the future of the network, how to access the network, best practices for network users, and the coordinate system used by the network. The networks consist of permanent GNSS base stations, communications links, and server computers that together calculate corrections and send them to other mobile GNSS receivers in order to acquire real-time survey-quality field positions. Rinex data is also available for post processing positions.
