Hemisphere VECTOR V103™




Now with GLONASS, the IMO Wheelmarked Vector™ V103™  GNSS compass series is known for its superb heading and positioning performance. With the addition of GLONASS, the V103  now provides a more robust solution in critical areas where sky blockage occurs. The rugged IP69K design housing is sealed for the harshest environments. It incorporates fixed and pole mounting capability for both marine and land applications. The Vector V103  series is suitable for both dynamic positioning and professional marine surveys, as well as for machine control applications in agriculture, mining, construction, and other challenging applications.

The V103  utilize all of the recent innovations in Hemisphere’s Crescent® Vector GNSS technology. New Cross-Dipole low-multipath antennas are separated by 50 cm between phase centers, resulting in better than 0.3° heading performance while delivering position accuracy of better than 30 cm when using SBAS or Beacon corrections.

The Vector V103  support both NMEA 0183 and NMEA 2000 interfacing, enabling a seamless choice of communication protocols with Hemisphere GNSS’ messaging. Crescent Vector technology delivers accurate and continuous performance, including position, heading, heave, pitch, and roll. The stability and maintenance-free design of the Vector V103  series replaces traditional gyrocompasses and stand-alone GPS at a fraction of the cos


The Hemisphere GPS V103 Smart Antenna features the new IP69K design housing that is completely sealed, allowing it to work in the harshest environments. It is well suited for professional and commercial land and marine applications, as well as for machine mounting in construction, open pit mining and other applications.

The V103’s Cross-Dipole antennas are located 50 cm apart between phase centers and offers the best heading performance and accuracy of up to 60 cm 95% of the time when Beacon or SBAS corrections are used. The V103 supports NMEA 0183 and NMEA 2000 interfaces, which offer a seamless choice of communication protocols with Hemisphere GPS’ messaging.

Hemisphere GPS’ COAST technology allows the V103 smart antenna to use previously collected differential correction data to provide sub-meter positioning for 40 minutes at times of signal interferences or when no differential signal is available. Furthermore, the V103’s built-in gyro and tile sensors are capable of delivering fast start-up times and continuous updates even when GPS signals are lost temporarily.
