Vector H328 Compass Board

Hemisphere GNSS – Vector™ H328 Compass Board

The Hemisphere GNSS Vector H328 is a multi-frequency, multi-GNSS, low-power, high-precision, positioning and heading OEM board.



The Vector H328 is the most advanced GNSS heading and positioning board from Hemisphere GNSS. Ideal for robotics, autonomous vehicles, antenna pointing, marine survey and any application where high-accuracy positioning and heading is required.

The Vector H328 has scalable positioning and is field upgradeable from other manufacturers’ modules in addition to all Hemisphere software and service options.

The tilt sensors provide pitch, roll data and assist in fast start-up and reacquisition of heading solutions. The Gyro provides smooth and fast heading and reliable < 0.5° per min heading for periods up to 3 min. when loss of GPS has occurred.
