056353/J NAVIKNOT 600 SD
6-38 GPS Setup
Gyro Orientation
Configures the orientation of the rate gyro assembly on the satellite
PCB, relative to the vessel’s fore-and-aft line.
Settings: Forward
The arrow symbol on the electronics unit’s cover points
towards the bow.
Starboard
The arrow symbol on the electronics unit’s cover points
towards the starboard side.
Aft
The arrow symbol on the electronics unit’s cover points
towards the stern.
Port
The arrow symbol on the electronics unit’s cover points
towards the port side.
In all cases, the electronics unit must be mounted such that
it is aligned with the respective direction to within ±5°.
Heading Offsets
Sets the correction values (“deltas”) to compensate for existing offsets
of the heading sources relative to the vessel’s fore-and-aft line.
As only the GPS source is used within the NAVIKNOT 600 SD system, a
delta value must be entered for the GPS source only. This compensates
for misalignment of the GPS antenna support with the vessel’s fore-and-
aft line
Settings:
GPS
delta (correction value):
-9.9 – +9.9°
Determine the existing misalignment by comparing the GPS
heading as shown on the setup page with the true heading
from the vessel’s heading reference (e.g. the gyrocompass).
Enter the required delta to match the GPS heading with the
heading reference. The correction is effective immediately,
so that the GPS heading displayed on screen should now
exactly match with the reference.
MAG (Magnetic)
Not applicable in NAVIKNOT systems; do not alter the fac-
tory default setting (delta = 0.0°).
EXT (External)
Not applicable in NAVIKNOT systems; do not alter the fac-
tory default setting (delta = 0.0°).
