Hemisphere Vector VS330 GNSS Receiver

Hemisphere Vector VS330 GNSS RTK Heading & Position Receiver

Vector Hemisphere VS330 GNSS receiver and compass support GPS/GLONASS L1 and L2 signals, with RTK capability. It utilizes the Eclipse™ GNSS technology to provide reliable positioning results for precise marine and land applications that require highly accurate heading and RTK position.

Vector Hemisphere VS330 offers excellent multipath mitigation, which can effectively reduce signal interferences caused by multipath, which happens when signals are being reflected from surfaces such as windows of buildings, trees, or even the ground. Furthermore, the VS330 receiver is equipped with two antennas that can be mounted separately according to the needs of the user-application.

VS330 Hemisphere heading receiver, with its display and user interface, can be conveniently installed near the operator. The two antennas are mounted separately and with a user-determined separation to meet the desired heading accuracy. The Vector VS330 uses L-band DGNSS/HP/XP and SBAS (WAAS, EGNOS, MSAS, etc.) for differential GPS positioning.
