Key Features & Benefits

Key Features & Benefits

  • Triple-Fix RTK Technology: Three independent RTK engines deliver up to 100% RTK availability, even in dense foliage and urban environments. 
  • Centimeter-Level Accuracy: Achieve 0.6 cm horizontal and 1.0 cm vertical accuracy. 
  • Tilt Compensation Without Calibration: Integrated IMU eliminates the need for calibration and remains immune to magnetic interference—measure confidently up to 60° tilt.

Advanced GNSS Technology

Advanced GNSS Technology

At the Viking’s core is the GAMA RTK engine, designed for next-gen processors and capable of evaluating more than 1,000 error parameters per second. The result: highly reliable positioning, even in the toughest conditions.

  • Signal & Frequency Diversity: Simultaneous tracking of all major constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC, plus L-Band and Galileo HAS).
  • GNSS+ Protection Suite:
    • AIM+ – Anti-jamming and anti-spoofing technology.
    • LOCK+ – Robust tracking under vibration and high dynamics.
    • IONO+ – Ionospheric scintillation monitoring, resilient during solar storms.
  • APME+ – Multipath mitigation for accuracy near buildings or heavy machinery.
