The NCU is the interface
between the in-water acoustic instruments, sensors and the
Navigation Computer which runs the acoustics positioning
software. In addition to accurately time stamping incoming
data from external devices such as GPS, the NCU also provides
power and communications for ship-borne acoustic transceivers.
A range of hardware interface
cards are available for interfacing Sonardyne transceivers
and external sensors. By simply plugging these cards into
the rear of the unit, the role of the Navigation Controller
Unit can be transformed from supporting simple to complex
acoustic operations.
For certain DP and drilling operations, the NCU can be configured
to offer dual and triple redundancy.
