• POSITION MODE and HEADING MODE can be toggled on and off at any
time while SeaStation is active. Targets will be re-acquired upon engagement.
• Align your vessel stern to wind/current to reduce engine activity.
• If you don't know which way to align the boat, use POSITION MODE to
let the boat find a stable heading then engage HEADING MODE.
• If engines are working very hard, try bumping the target heading so the
boat is closer to parallel with wind/current – see section 3.2.4.
• POSITION MODE on its own requires less engine activity than when
combined with HEADING MODE. Vessel heading usually changes minimally
in POSITION MODE thus it is recommended for most applications.
3.5 SeaStation faults
Drift faults
3.5.1
If the vessel drifts too far from its target position or heading, the display
will alarm:
Figure 3-4. SeaStation Drift Faults.
Drift alarms are usually a result of either:
1. The boat is not positioned well relative to current conditions. Try
aligning your boat to be more parallel with wind or current.
2. Conditions are simply too strong for SeaStation. You may need to
move to a more sheltered area.
In many cases, drift faults can be prevented by using POSITION MODE on
its own. It is more difficult for SeaStation to hold position and heading at
the same time. If heading is not truly required, disengage this mode.
3.5.2
GPS-Compass faults
There are two types of GPS faults:
1. Communication Fault — If a communication fault occurs, contact technical
support for assistance.
2. Signal Fault — Often a signal fault is due to the GPS-Compass having
no signal or a poor quality signal. Try moving to an area with better sky
visibility, or give the system more time to track and acquire satellites.
