1. This location provides optimal GPS
performance (above decks).
2. In this location, GPS performance may be less
effective.
3. This location is NOT recommended for GPS
antenna.
Vessel construction
The construction of your vessel can have an impact
on GPS performance. For example, the proximity
of heavy structure such as a structural bulkhead,
or the interior of larger vessels may result in a
reduced GPS signal. Before locating equipment
with an internal GPS antenna below decks, seek
professional assistance and consider use of an
external GPS antenna mounted above decks.
Prevailing conditions
The weather and location of the vessel can affect the
GPS performance. Typically calm clear conditions
provide for a more accurate GPS fix. Vessels at
extreme northerly or southerly latitudes may also
receive a weaker GPS signal. GPS antenna mounted
below decks will be more susceptible to performance
issues related to the prevailing conditions.
Viewing angle considerations
As display contrast, color and night mode
performance are all affected by the viewing angle,
Raymarine recommends you temporarily power up
the display when planning the installation, to enable
you to best judge which location gives the optimum
viewing angle.
