Product Review: Carlson Viking RTK

CarlsonVikingFieldSS1

The Carlson Viking RTK Receiver is Carlson Software’s next-generation GNSS Smart Antenna, built in Maysville, Kentucky, and engineered to provide professionals in surveying, engineering, and construction with unmatched accuracy and speed. Designed to excel in environments where traditional receivers often fail—such as dense forests and urban canyons—the Viking ensures reliable performance through a suite of advanced features.

Core Technologies and Advantages

The Viking’s round top protects an industry-leading antenna element.

The Viking stands out by integrating industry-leading hardware with the Carlson GAMA® RTK engine. Key technical highlights include:

  • Triple-Fix RTK: For the first time in the industry, the Viking utilizes two GNSS chips and three independent RTK engines. This redundancy delivers exceptional reliability, only reporting Triple-Fix when all three engines align within tolerances, essentially eliminating any chance of “false-fixes.”
  • Calibration-Free IMU: The receiver features a six-axis inertial sensor that provides automatic pole tilt compensation. This system is completely calibration-free and immune to magnetic interference, allowing users to measure points faster without manually leveling the pole.

■ GAMA® RTK Engine: Carlson’s proprietary engine leverages Viking’s multi-core CPU and high-performance GNSS antenna for unmatched speed and stability.

■ Superior Resilience: To combat modern field challenges, the Viking includes advanced anti-jamming and anti-spoofing technology, as well as multipath mitigation and advanced resistance to solar storms.
