Tenders and RFP’s. Challenges and Benefits of VRS. Errors can be Reduced in VRS. Apps & Software Updates. Submit Article and Job. A virtual reference station is an imaginary, unoccupied reference station which is only a few meters from the RTK user. For this position, observation data are created from the data of surrounding reference stations as though they had been observed on that position by a GPS receiver. Virtual Reference Station (VRS) networks use real-time kinematic. To reach centimeter-level or...
