Introduction
Overview
The Vector™ V103™ GNSS Compass and V113™ GNSS Compass supports GPS and GLONASS which is
based on Hemisphere GNSS’ exclusive Crescent® and Crescent Vector™ H200™ GNSS module.

Note: When referring to both the Vector V103 GNSS Compass and the Vector V113 GNSS Compass this manual
uses the term V103/113. When referring to either product this manual uses either V103 or V113, respectively.
The V103/113 is a complete GPS and GLOANASS compass system for heading and positioning in a single
enclosure that requires only one power/data cable connection. With its CAN support and ease of installation, the
V103/113 is the perfect solution for professional, commercial marine, Radar/ARPA, AIS, ECDIS, scanning sonar
and machine control applications.
There are no mechanical parts such as gimbals or rotating motor, thus the V103 and V113 compass is free from
routine maintenance. Since heading is determined from GNSS there is no need to wait for settling time,
gyrocompass calibration and speed corrections. Our Vector performance is not affected by geomagnetism making
it the perfect solution for any marine application.
The V103/113 is an integrated system that houses the following:
 Crescent and Crescent Vector H200 module
 Dual GNSS multipath-resistant antennas
 DGPS beacon module and H-field beacon antenna (V113only) Power supply
 Single axis gyro
 Tilt sensor on each axis (X and Y axes)
The gyro and tilt sensors are present to improve system performance and to provide backup heading information in
the event a GNSS heading is not available due to signal blockage. The gyro provides a substitute heading for a
short period, accurate to within 1º per minute for up to three minutes.
Note: The V103 GNSS Compass is identical to the V113 GNSS Compass with the exception that it does not
contain a DGPS beacon module and antenna. If you purchased the V103 GNSS Compass, disregard the sections
of this manual that discuss the beacon signal, receiver operation, and implications to installation relating to the
beacon signal.
The Crescent Vector H200 module supports multiple RF front ends - enabling tighter coupling of measurements
from separate antennas for use in heading-based products. Users will achieve excellent accuracy and stability due
to Crescent’s more accurate code phase measurements, improved multipath mitigation, and fewer components.
