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.
Figure 1-1: V103/V113
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.

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.
Parts List
Note: The V103/113’s parts comply with IEC 60945 Section 4.4: “exposed to the weather.”

Installation
Mounting Location
This section provides information on determining the best location to mount the V103/113. To use the mounting
template, go to the HGNSS website and navigate to Products/Position & Heading/V103/113.
GNSS Satellite
When considering where to mount the V103/113, consider the following satellite reception recommendations:
 Ensure there is a clear view of the sky available to the V103/113 so the GNSS and SBAS satellites are
not masked by obstructions that may reduce system performance
 The V103/113 computes a position based on the internal primary GNSS antenna element, mount the
V103/113 where you desire a position with respect to the primary GNSS antenna (located on the end
opposite the recessed arrow on the underside of the enclosure)
 Locate any transmitting antennas away from the V103/113 by at least a few meters to ensure tracking
performance is not compromised, giving you the best performance possible
 Make sure there is enough cable length to route into the vessel to reach a breakout box or terminal
strip
 Do not locate the antenna where environmental conditions exceed those specified in Table B-6
Beacon Reception
When using the V113’s internal beacon receiver as the correction source, consider the possible mounting
locations from the perspective of ambient noise within the beacon band.
Keep the following in mind when deciding upon a location with respect to maximizing beacon performance:
 Ensure that the antenna is as far as possible from all other equipment that emits electromagnetic
interference (EMI), including DC motors, alternators, solenoids, radios, power cables, display units,
and other electronic devices.
 If you are installing the antenna on a vessel, mount the Vector compass as high as possible,
considering maintenance and accessibility. In addition, ensure that the antenna is higher than the
highest metal object on the vessel.
 If a radar system is present, mount the antenna outside the path of the radar beam.

V103/113 Vector User Guide Chapter 2-Installation Page 6 of 35
The V113’s internal beacon receiver calculates a signal-to-noise ratio (SNR), measured in decibels (dB), that
indicates the receiver’s performance. The SNR is the height of the signal above the noise floor: the higher the
SNR, the better your beacon receiver demodulates the signal.
The optimum antenna location will be a position where your average SNR is highest. You should turn on all
accessories you intend to use during normal operation when locating the best position for the antenna. By
monitoring the SNR, you can determine the optimum location with respect to beacon reception. The SNR is
available in the $CRMSS NMEA message described in the Hemisphere GNSS Technical Reference Guide.
Environmental Considerations
Hemisphere Vector compasses are designed to withstand harsh environmental conditions; however, adhere to
the following limits when storing and using the V103/ 113:
 Operating temperature: -30°C to +70°C (-22°F to+158°F)
 Storage temperature: -40°C to +85°C (-40°F to+185°F)
 Humidity: 95% non-condensing
VHF Interference
VHF interference from such devices as cellular phones and radio transmitters may interfere with GPS
operation, however the Vector compass can still track GLONASS satellites maintaining heading and position.
For example, if installing the V103/113 near marine radios consider the following:
 VHF marine radio working frequencies (Channels 1 to 28 and 84 to 88) range from
 156.05 to 157.40 MHz. The L1 GPS working center frequency is 1575.42 MHz. The bandwidth is +/-
2MHz to +/- 10 MHz, which is dependent on the GNSS antenna and receiver design.
 VHF marine radios emit strong harmonics. The 10th harmonic of VHF radio, in some channels, falls
into the GPS working frequency band, which may cause the SNR of GNSS to degrade significantly.
 The radiated harmonic signal strength of different brands/models varies.
 Follow VHF radio manufacturers’ recommendations on how to mount their radios and what devices to
keep a safe distance away.
 Handheld 5W VHF radios may not provide suitable filtering and may interfere with the V103/113’s
operation if too close
Before installing the Vector Compass use the following diagram to ensure there are no nearby devices that
may cause VHF interference.
