Virtual Reference (VRS) Network for Eastern Washington and Northern Idaho
A VRS Network is being established that will cover all of Spokane County and parts of Northern Idaho. The network was established through an interagency agreement between Spokane County, City of Spokane, Pend Oreille County and the Eastern District of Washington Department of Transportation.
Spokane County’s VRS Station is up and running. Our station is located near the town of Latah. The exact coordinates for Point Latah (LTAH) are: 47° 16' 56.718296'' N, 117° 9' 50.043635'' W, and 737.229 meters.
The signal goes from a Trimble NetRS to a US Robotics 56K modem into an analog phone line to the Survey office, into another 56K modem. From there it goes into a Lantronix converter, into our network and over to the Washington State Reference Network (WSRN).
You can review the status of Point Latah and other station in the WSRN by going to: www.wsrn.org. Once there, sign in as a guest and select “Satellite Tracking”.
