Figure 4-25 RC25/RFC35R Rate Compass Mounting
The heading sensor is the most important part of the AP50
system and great care must be taken in choosing the mounting
location. The heading sensor can be mounted at any location
where there is a minimum of magnetic interference and
minimum movements. It is not recommended to use the
RC25/RFC35R on steel vessels. However, if this is done, it
should be installed 1 meter above the steel deck to obtain
optimum performance.
Note ! In order to prevent excessive movements, an autopilot heading
sensor should not be installed on the fly bridge or on the mast.
The rate compass can be deck-mounted or on the bulkhead,
athwartship or alongship. The heading offset feature of the
AP50 will compensate for the mechanical offsets that may be a
result of the selected location and orientation of the RFC35R.
