Overview

The Vector V103 and V113 GPS compasses from Hemisphere GNSS are known for their superb positioning and heading performance and now include GLONASS. With GLONASS added, both models now provide a robust performance in critical areas where sky blockage takes place. They can also handle the harshest environments due to the rugged IP69K design housing, incorporating pole and fixed mounting capability for both land and marine applications.

The Vector V103 and V113 are suitable for both professional marine surveys and dynamic positioning, and can also be used for machine control applications in mining, agriculture, construction, as well as many other challenging applications.

The V103 and V113 series GPS compasses have all the recent Hemisphere Crescent Vector GNSS technology incorporated. The new low-multipath Cross-Dipole antennas have a 50 cm separation between phase centers. This results in a heading performance of better than 0.3°, while the position accuracy is better than 30cm when Beacon or SBAS corrections are used.

Both models include NMEA 0183 and NMEA 2000 interfaces, allowing seamless communications with Hemisphere’s GNSS messaging. The Crescent Vector technology used delivers continuous, accurate performance, which includes heading, position, pitch, heave and roll. The maintenance-free design and stability of the Vector V103 and V113 compasses replaces both stand-alone GPS and traditional gyrocompasses at a greatly reduced cost.

Features

  • Enhanced heading performance with GLONASS
  • IMO type approved as a Transmit Heading Device (THD)
  • Additional satellite tracking ensures a robust solution
  • Flexibility for easy integration into NMEA 0183 and 2000 interfaces
  • Accurate heading up to 3 minutes during GNSS outages
  • Maintains heading and position lock in obstructed areas
  • Integrated tilt and gyro sensors provide fast start-up times and heading updates during loss of satellite signals
