OCTANS NANO SYSTEM OVERVIEW
OCTANS NANO is a 4,000m depth rated fiber-optic gyrocompass and Attitude sensor for subsea applications such as
ROV or any subsea vehicle navigation as well as attitude monitoring of subsea structures. OCTANS NANO provides
true heading, roll, pitch, as well as heading, roll and pitch rates of turns and accelerations even in highly dynamic
and harsh environments.
TYPICAL ROV INSTALLATION
This guide describes how to install OCTANS NANO for ROV navigation. No lever arm measurements are required.
OCTANS NANO being versatile, you have to define its configuration to insure optimal operation.

INSTALLING & CONNECTING OCTANS NANO
OCTANS NANO has to be aligned either with vessel/ROV reference frame either with imagery survey
sensor. Reference frame center is defined by (P) and shown in the figure below, it is not located at the
center of the unit. iXBlue product reference frame may differ from 3rd party equipment convention.
OCTANS NANO must be mounted on a rigid
structure (plate) firmly linked/attached
to the vehicle/platform.
I.e. avoid unexpected displacement against
vehicle or third party equipment reference
frame.
Step 1 Place OCTANS NANO on the mounting plate/surface

Step 2 Pressing the OCTANS NANO left edge against the reference baseline or pins along X2 direction
For mechanical installation
recommendations, refer to:
Inertial Products –Application
Note –Mechanical Integration
of Inertial Systems
(Ref.: MU-MECHAAPN-AN-001)
Distance from each pin for alignment:

Important
Shield link should be done at one end only to avoid ground loops unless shield is used as an electrical ground.
It is recommended to link external cable shielding to mechanical ground.

Step 4 Restarting the system
²²²²²²²²²²
Accuracy required on the latitude input
is less than 1°.
Enter the vessel speed or the
estimated adrift speed.
The heading output is sensitive to the
vessel speed towards North. This error
is given by the following formula:
Heading[deg]= (Vnorth[knot]/5).seclat
The required speed input accuracy is
better than 4 knots.
Manual position can be configured via
advanced commands (i.e. ASCII
commands) on the repeater port.
For more information refer to “AHRS –
Advanced configuration” document:
Ref.: MU-AHRS-AN-002.
As soon as you have clicked on the
Restart button, OCTANS NANO starts
its alignment phase with the
manually input position.
During the initial alignment phase,
the system should be kept static or
follow constant speed and heading.

CONFIGURING THE MECHANICAL PARAMETERS
It is considered that the OCTANS NANO
is mechanically aligned with the vehicle.
However OCTANS NANO can be mounted
in any orientation and it is possible to
align the output.
For more information refer to “Web-
based interface user guide” document.
Ref.: MU-INSIII -AN-021

Step 2 Configuring the output parameters in the Web-Based User Interface
User can freely configure each output.
To select an UDP Protocol (User Defined
Protocol) select From the library in the Protocol
drop-down list then click on the Browse button
to reach the script file available on the CD-ROM.

OPERATING OCTANS NANO
As soon as OCTANS NANO is powered up, it starts its alignment phase.
Alignement uses as initialization parameters the "Manual position" and "Manual velocity" (see page 11) saved in the
nonvolatile memory of the system; alternatively, if available, any external input position and velocity.
During the alignment phase, heading and attitude data are available, but have not reached full accuracy.
Specified accuracy on heading, roll and pitch is reached at the end of the alignment phase.

(at powering on or software restart)
Important
OCTANS NANO is delivered with default latitude set to iXBlue’s factory location.
Without user update or external GPS connected, OCTANS NANO will start seeking north with France latitude, which
may be quite different from the current latitude.
Latitude has to be modified by the user (see page 11). Once this modification is performed, it is recommended to save
it and restart the system. This procedure allows OCTANS NANO to enter the correct latitude value as an input in the
North finder algorithm as soon as computation starts. OCTANS NANO will then reach full accuracy after the
alignment phase.
Otherwise OCTANS NANO will not perform according to its specification.
At any power supply outage, OCTANS NANO restarts its full alignment process. It is recommended to secure power
supply on UPS.

Step 2 Monitoring OCTANS NANO
²²²²²²²²²²
The embedded Built In Test, also
called Status, monitors OCTANS NANO
stats warning and failures thanks to
large set of flags.
Status are displayed on the web-based
user interface with the following
colors:
Message in blue:information
message
Message in orange: warning
message
Message in red: error message
Grey:disabled
For explanation of the status, refer
to AHRS-Interface Library (ref: MU-
AHRS-AN-005).
For this example:
- OCTANS NANO is ready
- Manual Lattitude and Manual
Longiture are used
- Polar Heading is not valid

TROUBLESHOOTING
OCTANS NANO has a Built-In status and error Test (BIT) which raises alarms (through the color of the iXBlue Logo)
and displays messages in the OCTANS NANO User Interface.
If you encounter problems when installing or using OCTANS NANO, please refer to the following table.
If you still cannot resolve the problem, please contact IXBlue support (see previous page).

Web-based User interface
Incorrect URL address entered
in the Web browser
Type in back the URL address
Default address is 192.168.36.1xx, xx
being the last two numbers of your
OCTANS NANO serial number
Check computer IP address should be in
the same range as the unit.
The URL address has been
changed by another person
1) Retrieve the new OCTANS NANO IP
address: connect the repeater cable to
your PC and start a serial terminal
(HyperTerminal, BBTALK, etc.)
configured at 19200 baud, no parity, 1
stop bit, 8 data bits. Reboot OCTANS
NANO once connected. You will get the
OCTANS NANO boot sequence message
that contains its attributed IP address
(line beginning with “IFCONF”)
