CONVENTIONS OCTANS 3000 OVERVIEW
OCTANS 3000 is both a fiber-optic survey-grade gyrocompass and a Motion Reference Unit for Marine applications.
The core of OCTANS 3000 is a compact strap-down Inertial Measurement Unit (IMU) which contains three accelerome-
ters, three fiber-optic gyroscopes, and a real-time computer. This unit computer is a Digital Signal Processor (DSP) chip
enabling complex real-time computation.
The heading search algorithm has been designed by IXSEA. Heading and attitudes are computed whether the system is
in movement or not, and without an external reference point. Computation is based on (filtered) measurement of shifts
in local gravity as the Earth rotates. It involves angle integration using quaternion algebra, a heading search algorithm,
and Coriolis force correction for vessel speed.
The OCTANS 3000 system is used to deliver:
• True heading, roll, pitch
• Heave, surge, sway
• Rates of turn and accelerations
OCTANS 3000 is delivered with a powerful and easy-to-use WEB-based User Interface, which allows a complete confi-
guration.
VERIFICATION OF THE PACK CONTENTS
You will find in the shipping case a Packing List detailing all the items delivered. This packing has been completed and
checked by IXSEA shortly before shipment, and should match the contents of the pack you have received.
However, we recommend that you check the contents of the pack and the equipment immediately on receipt of your
OCTANS 3000 unit. Specifically, you should check that all the items referred to above are present on delivery and that
none has sustained damage.
If you observe any non-conformity or damage, please inform the carrier and IXSEA without delay by certified mail,
describing in detail the problem encountered.

STEP 1 - OCTANS 3000 GUIDED TOUR
Connecting OCTANS 3000 to PC and Mains
As soon as OCTANS 3000 is powered up, it starts its 5-minute alignment phase. During this alignment phase, heading
and attitude data are available, but have not reached full accuracy (see figure 1). Specified accuracy on heading, roll and
pitch is reached at the end of the 5 minutes long alignment phase. Heave initialization occurs at each OCTANS 3000
powering on or soft restart. It is performed in parallel with the OCTANS 3000 alignment phase, but it is time set to 5 addi-
tional minutes. During the heave initialization phase, the heave, surge and sway outputs have not reached full accuracy.

Launching the WEB-based User Interface
Required environment:
• The workstation must be equipped with one of the following Web browser:
Mozilla Firefox version 3.5 and higher
Chrome version 4 and higher
Safari version 4 and higher
Opera version 10 and higher
Internet Explorer version 7 and higher
• Flash Player version 10 (and higher) must be installed on the workstation to visualize the compass
• For the data logging: Java Runtime Environment 1.6 (and higher)
The Control Pages opens:
During the first seconds the IXSEA logo is flashing grey-blue indicating that the Web-based User Interface is loading
the internal configuration of OCTANS 3000. Then the logo turns blue, the alignment sequence of OCTANS 3000 begins.
Menu Bar
The menu is blue when selected

WEB-Based User Interface - General Rules, Commands and Navigation
IXSEA logo handling
A click on the IXSEA logo opens the detailed status pop-up window and the compass disappears. This window summed-
up the status of: • The input ports
• The output ports
• The system
• The external sensors
You can close the pop-up by clicking either on the IXSEA logo or in the Status area.
Color Code
The color code applies for the indicators and text labels displayed in this pop-up window.
When a problem occurs, the color of the IXSEA logo changes and the detailed status pop-up automatically appears
showing immediately which equipment has raised the problem.
Table 1 – Color code definition
General Rules for Using Command Windows
The command windows allow you to display or modify OCTANS 3000 configuration parameters. At first delivery, these
parameters are set to default values. You have to modify them to fit your needs:
Scrolling list selection
• By selecting it directly in the scrolling list:
Note
you can also use the up arrow ([]) and down arrow ([]) keys to scroll in the list.
Tick box
• By selecting it by clicking in the dedicated box:
Color Definition
Grey inactivity
Flashing Grey/Blue System Configuration (during initialization for example)
Blue Activity, nominal operation
Orange Activity, warning
Red Activity, alarm

Text box
• By typing it in the dedicated area:
Note
you can also use the up arrow ([]) and down arrow ([]) keys to increase or decrease
the numerical values.
Incorrect value are immediately indicated by red color:
Expanding hidden area
In order to keep each web-based page as small as possible, only the main parameters are default
visible. You can expand the hidden area by clicking on its text label title:
OK/Cancel buttons
Each command page contains the same buttons, they appear as soon as a modification or a selection
has been made in the command page:
To validate the new configuration and store it in the OCTANS 3000 PROM.
To return to the previous entered values.
Other Button
On “mouse over” action, orange color may surround a button to indicate that the action performed
by clicking on the button has consequences.
Examples of such action:
• OCTANS 3000 restart (the alignment process is repeated)
• Reset to factory settings (the customized configuration is lost)

Entering the Initial Latitude
All gyrocompasses, OCTANS 3000 included, are sensitive to the current latitude. However latitude needs to be updated
into OCTANS 3000 only if the ship changes latitude quite substantially. OCTANS 3000 has to know the latitude of its loca-
tion in order to find geographical North rapidly. If the latitude information input is incorrect, OCTANS 3000 will produce
an error.
IMPORTANT
OCTANS 3000 is delivered with a default latitude setting that corresponds to IXSEA's factory location. At first powe-
ring-on, without external GPS connected, OCTANS 3000 will start seeking north with this latitude input, which may be
quite different from the current OCTANS 3000 latitude.
Latitude has to be modified by the user. Once this modification is performed, it is recommended to save the current lati-
tude into OCTANS 3000 PROM and re-start the unit.
This procedure allows for the OCTANS 3000 to enter the correct latitude value as an input in the North finder algorithm as
soon as computation starts. OCTANS 3000 will then reach full accuracy after the 5 minutes alignment phase. Otherwise,
time for OCTANS 3000 stabilization will be increased due to the wrong initial latitude input when computation starts.
This procedure should be done whenever a unit is delivered from factory, or whenever a new firmware has been re-loa-
ded into the unit
