America’s Flagship GNSS Receiver for Unmatched Accuracy and Reliability
The Carlson Viking is Carlson’s flagship GNSS receiver, engineered for professionals who demand reliable centimeter-level accuracy in the field. Featuring innovative Triple-Fix technology, calibration-free tilt compensation, and flexible base or rover operation, the Viking delivers exceptional performance in challenging environments. Designed and assembled in the USA, it integrates seamlessly with Carlson SurvPC and Layout software to help surveyors, engineers, and construction professionals work faster and with greater confidence.
Why Choose the Carlson Viking?
The Carlson Viking is designed to eliminate the frustrations commonly experienced with traditional GNSS receivers. From dense urban environments to tree canopy and active construction sites, the Viking maintains reliable positioning while minimizing false fixes through advanced Triple-Fix RTK technology.
Its self-calibrating IMU allows survey crews to measure points accurately while holding the pole at angles up to 60°, reducing setup time and improving productivity throughout the day.
American engineering, premium hardware, and Carlson’s proven field software combine to create one of the most advanced GNSS receivers available today.
