V103/113 Vector User Guide Chapter 1 - Introduction
Page 3 of 35
The V103/113’s GPS antennas are separated by 50.0 cm between their phase centers, resulting in a heading
performance better than 0.30° rms. The V103/113 provides heading and positioning updates of up to 20 Hz and
delivers positioning accuracy of 0.6m 95% of the time when using differential GPS corrections from beacon (V113
only) or from Space Based Augmentation Systems (SBAS).
The V103/113 also features Hemisphere GNSS’ exclusive COAST™ technology that enables Hemisphere GNSS
receivers to utilize old differential GPS correction data for 40 minutes or more without significantly affecting the
positioning quality. The V103/ 113 is less likely to be affected by differential signal outages due to signal blockages,
weak signals, or interference when using COAST.
If you are new to GNSS and SBAS, refer to the Hemisphere GNSS Technical Reference Guide (for further
information on these services and technologies before proceeding.
