Trimble® VRS Now™ Positioning Services

Trimble VRS Now™  

One of the most exciting technologies to emerge in  surveying in recent years is that of Trimble’s Virtual Reference Stations (VRS) for Real Time Kinematic (RTK) GNSS surveys.

Seiler Instrument Company has been a pioneer in VRS networks in the Midwest, beginning with the private, cooperative MWRTK network.  This experience led to us facilitating and constructing state wide Real Time Networks for the Missouri Department of Transportation and the Wisconsin Department of Transportation. 

Trimble® VRS™ corrections are more important now than ever before, due to increasing need for real-time high accuracy positioning.
