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.

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

Entering the Initial latitude
OCTANS 3000 has to know the latitude of its location in order to find geographical North rapidly. Accuracy required on
the latitude input depends on the current latitude: 3 degrees accuracy on latitude at 45 degrees latitude, and 1 degree
accuracy for latitudes below 30 degrees.
Step Action
1. Launch the Web-based User Interface from the WEB browser hosted on the workstation. By entering its
URL address (default address is 192.168.36.1xx, xx being the two last numbers of the OCTANS 3000 serial
number). The Control page opens.
2. Select INIT & UPDATE under SETUP menu.
The following page displays:
3. Enter the correct initial latitude.
Latitude is entered as a signed value in degrees with a resolution of 0.01 degree: positive (0 to 90 degrees)
in the northern hemisphere, negative (-90 degrees to 0 degree) in the southern hemisphere.
4. Click on OK button.
5. End of procedure.
Configuring the Inputs/Outputs
Up to five inputs/outputs are available: A, B, C, D and E. For each input/output, you can define the following parameters
(refer to OCTANS 3000 User Manual - Part 4 for details on these parameters) :
• In both directions: the Physical Link to receive and transmit data, the protocol and for the
- Serial case: Parity, Stop Bit (StopBit), Level and Baudrate
- Ethernet case: Transport layer, IP Address and Port socket number
• For the Output Direction:
- Lever arm: to specify the lever arm used: Primary, Secondary A, Secondary B or Secondary C. Motion sensing out
put on the protocol selected will be the motion measured at the external monitoring point defined by the lever arm.
- Either Rate (ms) the time interval in milliseconds between the beginning of two consecutive outputs
- Or Synchro In: when this option is selected, the output frequency is determined by the input coming from the input
Pulse A, Pulse B, or Pulse C
- ZDA checkbox: Tick it if you want to add the ZDA frame to the NMEA protocol selected (only available for NMEA

STEP 3 - MORE...
The previous steps consist only of the basic configuration of your OCTANS 3000 system. You will find hereafter a list of
other possible configurations. Details on these configurations can be found in the OCTANS 3000 User Guide.
OCTANS 3000 Reference Frame and Vessel Frame Not Aligned
OCTANS 3000 measures heading and attitude with respect to its reference frame defined by the 3 axes X1, X2 and X3 (see
Figure 2). OCTANS 3000 reference frame may not be parallel to the vessel reference frame. In such case, heading and
attitude outputs can be compensated for angular misalignments of OCTANS 3000 relative to the vessel reference frame
so that OCTANS 3000 outputs heading and attitude of the vessel.
This is done by setting misalignment bias for the three reference axis. These biases are the Euler angles which relate
OCTANS 3000 and vessel reference frame. Vessel reference frame is depicted on Figure 4.
Figure 4 - Vessel Reference Frame
For more details about the misalignment bias, refer to Part 2 of the OCTANS 3000 User Guide.

2010-06/MU/OCT 3kG4 /001 / Ed. B
External Monitoring Points
OCTANS 3000 is able to calculate the motion of several external monitoring point: one primary and three “secondary”
monitoring points can be user-configured. For each of those external monitoring points, data can be output with different
settings including serial or analogue I/O. In particular, at each location, a different protocol can be set.
External monitoring points are defined by their “Lever Arm” to OCTANS 3000 center of measurement P. This lever arm
is the triplet of cartesian coordinates (LV1, LV2, LV3) defining the position of external monitoring point M with respect to
OCTANS 3000 center of measurement P (defined in Figure 2) in the vessel reference frame (XV1, XV2, XV3) - see Figure 5.
Figure 5 - Definition of lever arms
For more details about the external monitoring points, refer to Part 2 of the OCTANS 3000 User Guide.
Pulse Input / Output
Three pulse Inputs and one pulse output are available on OCTANS 3000. For more details about
• The pulse connector pins, refer to Part 2 of the OCTANS 3000 User Guide.
• The available protocols, refer to Part 4 of the OCTANS 3000 User Guide.
Latitude Input from a GPS
For OCTANS 3000, there is no limit on latitude compensation. A GPS can be connected to OCTANS 3000 to input the real
time latitudes.
For more details about the GPS connections refer to Part 2 of the OCTANS 3000 User Guide.
