Hemisphere Vega 34 GNSS Compass Board - Advanced Heading & RTK Positioning Module

Product Details

The Hemisphere® Vega™ 34 GNSS Compass Board is a state-of-the-art dual-antenna GNSS module designed for applications requiring high-precision heading, RTK positioning, and reliable performance in challenging environments. Engineered with Hemisphere's Athena™ GNSS engine and Atlas® L-band correction service, the Vega 34 delivers centimeter-level accuracy, fast initialization, and robust performance across multiple constellations. This compact yet powerful board supports GPS, GLONASS, BeiDou, Galileo, QZSS, and NavIC (IRNSS), ensuring global coverage and future-proof compatibility. With dual-frequency heading, multi-frequency positioning, and RTK-enabled heave accuracy up to 5 cm RMS, it is ideal for marine, surveying, UAV, and industrial applications where precision and reliability are critical. The Vega 34 incorporates dual antenna ports for fast and accurate heading over short baselines, while its multi-axis gyro and tilt sensors provide stable coverage during short GNSS outages. Advanced Cygnus™ interference mitigation and strong multipath rejection ensure consistent performance even in high-interference environments. Key performance highlights include: Extremely accurate heading: 0.04° RMS @ 2.0 m antenna separation RTK accuracy: 8 mm + 1 ppm (horizontal), 15 mm + 2 ppm (vertical) Atlas® L-band corrections: from sub-meter to 4 cm RMS accuracy Update rate: 10 Hz standard (1 Hz or 20 Hz optional) Timing precision: 20 ns accuracy with PPS output Heave accuracy: 30 cm RMS (DGNSS), 5 cm RMS (RTK) The board is designed for scalable solutions—users can start with single-frequency operation and upgrade to full multi-frequency RTK performance as needed. Its 34-pin connector ensures easy migration from previous Hemisphere modules, making it a cost-effective upgrade path. With low power consumption (<2.5 W), wide operating temperature range (-40°C to +85°C), and rugged compliance with EP455 shock and vibration standards, the Vega 34 is built for demanding field conditions. Multiple communication interfaces are supported, including 4x CMOS serial ports, USB host/device, CAN bus (NMEA2000, ISO 11783), PPS output, and event input, ensuring seamless integration into diverse systems. Whether deployed in marine navigation, precision agriculture, surveying, autonomous vehicles, or UAV guidance, the Vega 34 delivers unmatched accuracy, reliability, and flexibility. Its compact form factor (71 × 46 × 10 mm, 24 g) makes it easy to integrate into space-constrained designs without compromising performance. By combining Hemisphere's Atlas correction services, Athena RTK engine, and advanced interference mitigation, the Vega 34 sets a new benchmark for GNSS compass boards—offering scalable, future-ready solutions for industries that demand precision.
