IV.4 DVL Ready Option
The DVL Ready option includes
•
A DVL WHN Type (from RDI, user’s manual provided on a CD-ROM)
•
A dedicated mounting plate (see Figure 3)
•
A dedicated PHINS to DVL cable (comprising two parts, see Figure 3)
The ROVINS DVL ready is delivered with the DVL axes already calibrated with respect to
the ROVINS ones. This feature avoids a long time consuming and dedicated sea
calibration procedure to measure heading and pitch misalignment of DVL with respect to
PHINS. This procedure is very similar to a patch test performed with a multibeam.
Calibration can also be performed by the owner. The ROVINS Calibration with RDI
Workhorse DVL is detailed in the document
INS – Application Note – INS Calibration with
RDI Workhorse DVL (Ref.: MU-INSAPN-AN-001)
.
The characteristics and operation of the DVL is described in the RDI user’s documentation
provided with your ROVINS. A mechanical drawing of the ROVINS with DVL ready option
is provided in Figure 3. The interface plate used to couple ROVINS or ROVINS with the
DVL is sketched on Figure 2 and Figure 3.
ROVINS is fixed on this plate using six CHC M6 screws. Two centering pins, fixed by
press in the 5 H7 holes on the interface plate, are provided for ROVINS alignment (see
We recommend to push PHINS against the pins in X2 direction (arbitrary choice) while
securing the screws to insure mounting repeatability.
The DVL is fixed on interface plate using
four M8 screws. Two centering pins, inserted in 8
H7 holes, are provided for DVL alignment.
