Hemisphere Vega 40 GNSS Compass Board - Advanced Heading & RTK Positioning Module

Product Details

The Hemisphere Vega™ 40 GNSS Compass Board, offered by Xtragen Technologies Pvt. Ltd., is a next-generation high-precision GNSS module designed for advanced heading, positioning, and navigation applications. Built with dual-antenna technology and powered by Hemisphere's Athena™ GNSS engine, the Vega 40 delivers centimeter-level RTK accuracy, robust heading performance, and reliable operation even in challenging environments. This compact and lightweight GNSS board is engineered for machine control, marine navigation, surveying, UAVs, and autonomous systems, where precise heading and positioning are critical. With support for multi-frequency, multi-constellation GNSS signals (GPS, GLONASS, BeiDou, Galileo, QZSS, IRNSS, and Atlas® L-band), the Vega 40 ensures global coverage, fast initialization, and superior reliability. Key highlights include: Dual-antenna ports for fast, high-accuracy heading over short or long baselines. RTK-enabled heave measurement with 5 cm RMS accuracy, ideal for marine and offshore applications. Atlas® L-band correction service support, delivering scalable accuracy from meter-level to sub-decimeter performance. Strong multipath mitigation and interference rejection, ensuring stable operation in urban or obstructed environments. Integrated multi-axis gyro and tilt sensors for reliable coverage during short GNSS outages, maintaining heading stability (<1° drift per minute). Excellent coasting performance for continuous navigation when signals are temporarily lost.
