Calgary, AB - Hemisphere GPS introduced the Vector VS330 and Vector VS131 GPS compass products that provide high performance heading, position, heave and attitude data. The new Vector products are designed for professional marine applications such as hydrographic and bathymetric surveys, dredging, oil platform positioning and buoys that demand the highest level of 3D positioning accuracies.

Based on Hemisphere GPS’ Eclipse GNSS technology, Vector VS330 utilizes the most accurate differential corrections including RTK, L-band, SBAS and beacon. The smart intelligence from the MFA firmware provides differential solutions by automatically switching to the next best differential source if the original source is no longer available.

Vector VS330 is Hemisphere GPS’ flagship receiver and computes heading information with better than 0.01 degrees accuracy when using a 10 meter antenna separation. Positioning accuracy is better than 1 centimeter in RTK mode or 4 centimeters when using OmniSTAR HP corrections. Vector VS330 also provides 5 centimeter RTK heave and 0.01 degree pitch and roll accuracies.

Combining Hemisphere GPS’ Crescent Vector and LX-2 receivers with two separate antennas, the Vector VS131 computes heading information with better than 0.03 degrees accuracy when using a 5 meter antenna separation and better than 50 centimeter position accuracy when using L-band, SBAS or beacon corrections. Vector VS131 accepts most differential correction signals for unparalleled flexibility to obtain sub-meter positioning in all regions.

The ruggedness of the Vector enclosure also makes it suitable for harsher environment installations that require very accurate heading and positioning solutions. The Vector’s versatility for providing heading, position, heave and motion makes it directly compatible with popular hydrographic and side scan survey packages. Vector VS330 and VS131 include an intuitive and easy-to-follow user interface to facilitate fast installations.

“Vector VS330 and Vector VS131 are premium additions to Hemisphere GPS’ Vector series product line,” said Phil Gabriel, vice president and general manager, Precision Products, for Hemisphere GPS. "As the demand for more rugged and precise GPS equipment increases, we are meeting this demand by exceeding the accuracy of competitors’ products while being significantly more affordable.”
