TracVision G6 Technical Manual
If uncertain of the best location
for the sensor module, make a
temporary installation and conduct
a compass calibration (as
described in Section 2.7,
"Calibrating the Sensor Module" on
page 42). Any necessary
adjustments to the sensor location
can be made based on the
calibration scores.

Choosing the Best Location for the GyroTrac Sensor Module
• Ideally, the sensor module should be mounted as
low as possible in the center of the vessel – but
NOT in the bilges.
• The mounting surface should be free of excessive
vibration and flexing.
•
Maintain at least four feet (1.3 m) separation
between the sensor module and any magnetized
materials, large ferrous masses, cranes, derricks,
other antennas, cables carrying high amperage
direct current, or battery banks. Take extra care
when mounting the sensor on a steel vessel; use an
aluminum, brass, plastic, or wood (NOT steel or
iron) platform to position the antenna at least four
feet (1.2 m) from the steel surface.
•
Be alert for devices that change their magnetic
characteristics when in use, such as CRTs
(computer and TV screens), radar magnetrons,
electric winches, loudspeakers, windshield wipers,
and other devices with DC motors. GyroTrac
cannot compensate for changing magnetic fields
created by these devices.
•
If you need to fabricate custom mounting brackets
for the sensor module, they should be made from
non-ferrous materials such as wood, brass,
aluminum, fiberglass, or plastic.
Choosing the Best Location for the ADCU
• The ADCU should be mounted in a dry location,
allowing enough room at the back for connecting
system cables.
• The ADCU should be placed so that the LCD
display is visible and the buttons are accessible.
• The ADCU is not susceptible to magnetic
interference and does not need to be mounted on a
level surface.
