Product catalog summary

Key Features

Extremely accurate heading with long baselines.
Supports multi-frequency and dual-frequency heading with GPS, GLONASS, BeiDou, Galileo, QZSS, NavIC (IRNSS), and L-band.
Atlas® L band capable to 4 cm RMS.
Athena™ GNSS engine for superior RTK performance.
5 cm RMS RTK-enabled heave accuracy.
Strong multipath rejection and Cygnus™ interference mitigation.
New multi-axis gyro and tilt sensor for reliable coverage during short GNSS outages.

Scalable Solutions

The Vega 34 offers scalable and field upgradeable heading and positioning with Hemisphere software and service options. It supports both single-frequency and multi-frequency modes for high accuracy L-band positioning from meter to sub-decimeter levels via the Atlas correction service.

Ease of Migration

The 34-pin connector allows for easy upgrades from previous Hemisphere modules. The Vega 34 features dual antenna ports for fast, high-accuracy heading, RTK positioning, and low power consumption.

Catalog excerpts

GNSS Compass Board tablets' The Vega 34 is our most advanced GNSS heading and positioning board. Vega 34 uses dual antenna ports to create a series of additional capabilities; including fast, high-accuracy heading over short baselines, RTK positioning, onboard Atlas L-band, RTK-enabled heave, low power consumption, and precise timing. With Vega 34, heading and positioning are scalable and field upgradeable with all Hemisphere software and service options. Utilize the same multi-constellation GNSS solutions in either single-frequency mode or employ the full performance and fast RTK initialization times over long distances with multi-frequency signals. High accuracy L-band positioning from meter to subdecimeter levels is available via the Atlas correction service. Leverage the 34-pin connector for easy upgradeability from previous 34-pin Hemisphere modules. • Extremely accurate heading with long baselines • Available multi-frequency position, dual-frequency heading supporting GPS, GLONASS, BeiDou, Galileo, QZSS, NavIC (IRNSS), and L-band • Atlas® L band capable to 4 cm RMS • Athena™ GNSS engine providing best-in-class RTK performance • Excellent coasting performance • 5 cm RMS RTK-enabled heave accuracy • Strong multipath rejection and Cygnus™ interference mitigation • New multi-axis gyro and tilt sensor for reliable coverage during short GNSS outages
