Vector Eclipse H328 OEM Board

Hemisphere Eclipse Vector H328 GNSS OEM Board

The Vector Eclipse H328 from Hemisphere GNSS is nearing End of Life (EOL). The final order date for the H328 will be June 30, 2021. Hemisphere GNSS recommends the Vega 40 GNSS Compass Board as a suitable replacement for the H328.



The Vector Eclipse H328 OEM Positioning and Heading Board includes Hemisphere’s new and innovative hardware platform and integrates Atlas GNSS Global Correction Service. It offers true scalability with centimeter-level accuracy in either single-frequency mode or full performance multi-frequency, multi-GNSS, Atlas-capable mode that supports fast RTK initialization times over long distances.

Powered by the Athena GNSS engine, the Vector Eclipse H328 provides best-in-class, centimeter-level RTK. Tested and proven, Athena’s performance with long baselines, in open-sky environments, under heavy canopy and in geographic locations experiencing significant scintillation is nothing short of cutting edge. Together with SureFix, Hemisphere’s advanced processor, the H328 delivers high-fidelity RTK quality information that results in guaranteed precision with virtually 100% reliability.

The Vector H328 utilizes dual antenna ports to create a series of additional capabilities to Eclipse Vector technology including fast, high-accuracy heading over short baselines, RTK positioning, onboard Atlas L-band, RTK-enabled heave, low-power consumption, and precise timing.

The 60 mm x 100 mm module with 24-pin and 16-pin headers is a drop-in upgrade for existing designs using this industry standard form factor. Furthermore, the H328 is ideal for robotics, autonomous vehicles, antenna pointing, marine survey, machine control and any application where high-accuracy positioning and heading is required.
