Leo Store - Hemisphere GNSS - Vega™ 40 GNSS Compass Board 1

Vega™ 40 GNSS Compass Board

Advanced Heading & RTK Positioning
 
The Vega™ 40 GNSS Compass Board utilizes dual antenna ports for enhanced capabilities: fast, high-accuracy heading, RTK positioning, onboard Atlas L-band, RTK-enabled heave, low-power consumption, and precise timing. Scalable and field-upgradeable, it ensures easy integration and offers high-accuracy positioning from meter to sub-decimeter levels with Atlas GNSS correction service.
