viii Safety Instructions
General Safety Information for the Operator
WARNING
Risk of misusage
Before using the NAVIGAT 100, operators must be appropriately trained
and familiar with all operating procedures and safety instructions con-
tained in this manual. The manual is to be completely read before the
first usage of the NAVIGAT 100.
Keep this manual during the entire service life of the product and always
have it readily available in a nearby location for reference.
WARNING
Risk of deviation
Never rely on one heading source alone to navigate a vessel.
Always confirm the plausibility of the NAVIGAT 100 heading and the
speed and position input data against all available aids to navigation.
WARNING
Limited heading data accuracy during alignment
After a power-up from cold, the NAVIGAT 100 requires an alignment
time of three hours before reliable heading data are available.
Power up the system at least three hours before leaving harbour.
Power down the system during long docking periods only.
Make sure that the NAVIGAT 100 has settled before using its heading as
the reference for heading control systems, RADAR, ECDIS, etc.
A magnetic compass heading source should be selected as reference
only in case of failure of the gyrocompass(es).
WARNING
Limited heading data accuracy during settling time
After a reset of the gyrosphere, the NAVIGAT 100 requires a settling time
of up to ten minutes before reliable heading data are available.
Do not reset the gyrosphere when navigating.
Make sure that the NAVIGAT 100 has settled before using its heading as
the reference for heading control systems, RADAR, ECDIS, etc.
A magnetic compass heading source should be selected as reference
only in case of failure of the gyrocompass(es).
WARNING
Risk of deviation
In case the magnetic compass is selected as active heading source and
magnetic compass heading messages HDG or HDM are selected as
NMEA input, this messages always transfer uncorrected / not true head-
ing.
Navigating with the magnetic sensor as active heading source may
therefore cause deviation.
Always have in mind, that the gyrocompass is providing true heading
and is the more reliable active heading source.
A magnetic compass heading source should be selected as active head-
ing source only in case of failure of the gyrocompass(es).

NAVIGAT 100 056373/D
Safety Instructions ix
WARNING
Risk of Deviation
A manually entered speed value as GPS input mode may badly influence
the north speed error correction functionality of the system and cause
deviation.
Do not enter manual speed values as GPS input without good reason
and select automatic speed data input by GPS again as early as possible.
Always have in mind, that automatic speed data input by GPS is the
preferable option for long time stable operation of the system.
WARNING
Risk of Deviation
An inactivated north speed error correction will influence the function-
ality of the NAVIGAT 100 and cause deviation.
Never inactivate the north speed error correction without good reason
and activate the north speed error correction again as early as possible.
Always have in mind, that an active north speed error correction is the
required option for reliable heading functionality and long time stable
operation of the CompassNet system.
WARNING
Risk of Deviation
Loss of or invalid speed and/or position input data will flaw the north
speed error correction of the NAVIGAT 100 and cause deviation.
Always have in mind, that the north speed error correction needs valid
speed and position input for reliable heading functionality and long time
stable operation of the CompassNet system.
Note
In case of loss or invalid speed and/or position input data, the north
speed error correction value cannot be calculated anymore, „OFF“ and
dashes replacing the value indication are shown at the North speed error
correction secondary info page and a corresponding „NO GYRO CORR
(HDG MANAGER“ warning will be raised.
WARNING
Risk of Injury
Unprotected contact with loose (unpacked) supporting fluid is consid-
ered to be harmful to personnel. Never allow unprotected contact of
loose (unpacked) supporting fluid to eye or skin.
Always use safety gloves and safety glasses as personal protective
equipment (PPE) when handling with loose (unpacked) supporting fluid.
Note
Loose (unpacked) supporting fluid is considered to be harmful to the
environment and must always be treated and disposed of as black water.
Never treat used supporting fluid as grey water and pour overboard or
flush down a drain.
Always treat used supporting fluid as black water and dispose of by e.g.
flushing down a toilet.
Always follow the environmental regulations for black water treatment
with loose (unpacked) supporting fluid.

xSafety Instructions
CAUTION
Risk of unstable/unreliable heading in polar waters
When operating the vessel in polar waters, the heading information of
the gyrocompass may become unstable/unreliable resulting in possible
deviation. For safe steering in polar waters, the heading information of
the gyrocompass may therefore NOT be used for navigation and heading
information of a GNSS (Global Navigation Satellite System) compass be
preferred instead.
CAUTION
Risk of damage to the gyrosphere through shut-down
A shut down of the NAVIGAT 100 system, while the vessel is navigating,
will damage the gyrosphere, as the gyrosphere is only self protected
against physical damage, as long as the system is running.
NEVER shut down the NAVIGAT 100, while the vessel is navigating.
A shut down of the NAVIGAT 100 system for good reason is only possible
when the ship is NOT navigating.
Note
Sperry Marine requires to NOT shut down the NAVIGAT 100 system as
long as the vessel is navigating, even when operating in polar waters
with possible unstable/unreliable heading.
CAUTION
Risk of damage/destruction through low temperatures
The supporting fluid in the gyrosphere container will start freezing at
temperatures below 0° C.
The NAVIGAT 100 must no longer be operated when the ambient tem-
perature at the gyrocompass’ location falls below - 10° C while the com-
pass is in operation or when the ambient temperature falls below 0° C
while the gyrocompass is not in operation.
Always make sure, that the ambient temperature is higher than 0° C
respective 10° C. If this is not possible, the gyrosphere container with
gyrosphere must be removed from the NAVIGAT 100 and transported to
a place with sufficient ambient temperature.
Make sure to remove the gyrosphere from the gyrosphere container if no
place with sufficient ambient temperature is available to eliminate dam-
age from freezing supporting fluid. The removal is to be executed in a
service work procedure by authorized service personnel only.
CAUTION
Risk of damage through unauthorized service
Scheduled maintenance or service work on the gyrosphere is to be car-
ried out by authorized service personnel only.
CAUTION
Risk of damage through unauthorized service
Only authorized service personnel is allowed to remove the gyrosphere
from the gyrosphere container.
Always keep to the mandatory safety requirements and the correct ser-
vice work procedure to remove the gyrosphere from the gyrosphere con-
tainer.

NAVIGAT 100 056373/D
Safety Instructions xi
CAUTION
Risk of mercury contamination
The gyrosphere type 3 and the gyrosphere container mod. 10/3 and
mod. 10/4 are designed for mercury free operation. Any usage of mer-
cury will severely contaminate the gyrosphere type 3 / gyrosphere con-
tainer mod. 10/3.
Never use mercury with the gyrosphere type 3 and the gyrosphere con-
tainer mod. 10/3.
In case of usage of mercury by mistake, the contaminated equipment
must not be used and all safety instructions of the Sperry Marine Mer-
cury Handling Procedure 026150-0000-000 must be followed accordingly.
CAUTION
Risk of defective gyrosphere caused by “GYRO FAILURE”
Should a “GYRO FAILURE” alarm occur during power-up, the compass
is not working properly.
De-energize the system and visually check the connections to the gyro-
sphere, the follow-up step motor and the shaft encoder.
If the failure reoccurs when the compass is powered-up again, the instal-
lation has not been carried out correctly or the gyrosphere is defective
and must be replaced.
CAUTION
Risk of damage through aggressive cleaning agents
Do not clean the compass with organic solvents, acetone or any other
substance which could damage or discolour plastic.
Only use water and soap or a mild detergent to clean the compass.
CAUTION
Risk of damage through overheating
A polluted or clogged air inlet grill located at the back side of the compass
housing will decrease the functionality of the cooling fan and cause over-
heating of the gyrocompass.
Always maintain the required distances around the compass housing to
enable sufficient air supply and full cooling fan functionality.
Make sure to regularly clean the air inlet grill from dust and dirt and check
the cooling fan functionality to avoid overheating.
CAUTION
Risk of damage through rotating masses
After power-down of the compass system, the gyroscopes need at least
45 minutes to stop rotating. Opening the container or draining off the
supporting fluid during rotating will damage the gyrosphere.
Wait at least 45 minutes after power-down of the compass system and
make sure, that the gyroscopes have stopped rotating before opening the
container or draining off the supporting fluid.
CAUTION
Risk of damage through misusage
Scheduled maintenance or service work on the gyrosphere is to be car-
ried out by authorized service personnel only.
CAUTION
Risk of damage through unauthorized service
Any service and installation work on the gyrosphere is to be carried out
by authorized service personnel only.
Never undertake service or installation work if unskilled for the certain
procedure.

056373/D NAVIGAT 100
xii Safety Instructions
CAUTION
Risk of damage through unauthorized service
Only authorized service personnel is allowed to remove the gyrosphere
from the gyrosphere container.
Always keep to the mandatory safety requirements and the correct ser-
vice work procedure to remove the gyrosphere from the gyrosphere con-
tainer.
CAUTION
Risk of damage through unauthorized service
Only authorized service personnel is allowed to remove gyrocompass
system components from the compass housing.
Always keep to the mandatory safety requirements and the correct ser-
vice work procedures to remove gyrocompass system components from
the compass housing.
CAUTION
Risk of damage to the gyrosphere
The gyrosphere is always to be transported in its carrying box in the orig-
inal transport container.
Do not throw or drop the transport container.
The transport container is to be transported in an upright position only.
CAUTION
Risk of damage to the gyrosphere
Carry the carrying box containing the gyrosphere by hand only and han-
dle it with extreme care.
Remove the gyrosphere from the carrying box only if required for imme-
diate installation.
CAUTION
Risk of data loss through shutdown of the compass / power-off condition
After a shutdown of the compasses main and backup power supplies it
cannot be guaranteed that all menu settings remain stored unchanged.
Always check that the alignment error correction value is noted correctly
in the setup tables, before switching-off the power supplies, see “Setup
and Configuration Tables” on page A-1 Appendix.
Always make sure to separately note the alignment error correction
value before switching-down the compass for maintenance or repair pur-
poses.
Note
A visual inspection of cables and connectors of the gyrocompass should
be carried out regularly to detect any signs of damage or deterioration.
Note
In case a „Speed Invalid“ alarm is triggered while the vessel is not in
motion or moving very slowly (e.g. when manoeuvring in harbour), this
is often caused by fast currents of fairway water increasing the - 5.0 kn
minimum speed default value.
In this case, the minimum speed value must be adjusted accordingly.
Note
The access code for the setup menu to reset the gyrosphere operation
time counter is disclosed to authorized service personnel only and is not
described in this manual.

Always make sure to separately note the alignment error correction
value before switching-down the compass for maintenance or repair pur-
poses.
CAUTION
Risk of damage/destruction after power-down
After power-down of the gyrocompass system, it may take up to
45 minutes for the gyroscopes to stop rotating and the gyrosphere is
therefore extremely sensible against any movement. Should the gyro-
sphere touch the wall of the container, the momentum of the rotating
gyroscopes will make it topple and damage the centre pin.
Avoid any movement of the gyrocompass system during power-down
time. Always be extremely careful in case the gyrosphere container must
be handled during power-down time.
CAUTION
Risk of damage/destruction through transport/wrong storing
When the container with the gyrosphere installed is temporarily stored
away, pack it into its original transport box or another suitable outer
package.
Always make sure that:
- the container is stored in an upright position,
- the temperature at the storage location cannot fall below 0°C,
- the container is not moved, tilted or subjected to shock.

xvi Safety Instructions
CAUTION
Risk of damage/restricted freedom of roll and pitch
An overhanging gyrosphere supply and pick off cable may restrict the
freedom of roll and pitch of the gyrosphere container.
The gyrosphere container can only use its full freedom of roll and pitch
when the gyrosphere supply and pick off cable is pushed deeply into the
bellows and the cable length minimized.
Always make sure to deeply push the gyrosphere supply and pick off
cable into the bellows to minimize the cable length when installing the
gyrosphere container. Never allow overhanging of the gyrosphere sup-
ply and pick off cable when installing the gyrosphere container.
CAUTION
Risk of damage to the gyrosphere
The gyrosphere is always to be transported in its carrying box in the orig-
inal transport container.
Do not throw or drop the transport container.

accurate wiring and keep all wires running inside the housing as short as
possible.
Always avoid to run wires from one side of the compass housing across
to the other.
CAUTION
Risk of earth faults
Wrong wiring of the cable shields makes the cables act as antennas
resulting in earth faults.
Always make sure to correctly draw back the cable shields and fasten the
cables to avoid earth faults.

Safety Instructions xvii
CAUTION
Risk of mercury contamination
The gyrosphere type 3 and the gyrosphere container mod. 10/3 and
mod. 10/4 are designed for mercury free operation. Any usage of mer-
cury will severely contaminate the gyrosphere type 3 / gyrosphere con-
tainer mod. 10/3.
Never use mercury with the gyrosphere type 3 and the gyrosphere con-
tainer mod. 10/3.
In case of usage of mercury by mistake, the contaminated equipment
must not be used and all safety instructions of the Sperry Marine Mer-
cury Handling Procedure 026150-0000-000 must be followed accordingly.
CAUTION
Risk of defective gyrosphere caused by “GYRO FAILURE”
Should a “GYRO FAILURE” alarm occur during power-up, the compass
is not working properly.
De-energize the system and visually check the connections to the gyro-
sphere, the follow-up step motor and the shaft encoder.
If the failure reoccurs when the compass is powered-up again, the instal-
lation has not been carried out correctly or the gyrosphere is defective
and must be replaced.
CAUTION
Risk of inaccurate alignment error correction
The compass must have been in continuous operation for at least 4 hours
before the alignment error can be determined accurately.
If bearing repeaters are used to determine the true heading, these must
be properly aligned to the vessel's fore-and-aft axis.
CAUTION
Risk of inaccurate magnetic compass calibration
The magnetic compass heading calibration corrects deviations due to the
combined effects of the magnetic environment, the particular sensor
being used and the receiving circuitry on the NAVIGAT 100 mainboard.
Therefore, a new calibration must always be carried out when:
- the steering magnetic compass is exchanged or newly adjusted,
- the magnetic compass heading sensor is exchanged and,
- when the NAVIGAT 100 mainboard is exchanged, in case a fluxgate sen-
sor is used.
Never use a true heading source, e.g. a gyrocompass, as the calibration
reference.
Never attempt to correct residual deviations of a properly adjusted mag-
netic compass by means of the calibration table.
CAUTION
Risk of inaccurate magnetic compass calibration
The magnetic compass used as the calibration reference must be prop-
erly installed and adjusted.
The procedure should be carried out in calm seas only.
CAUTION
Risk of inoperable device state
Updating a device’s firmware is a risky operation, as SUSI writes directly
to the device’s flash memory.
Under adverse circumstances, a failed update attempt may leave the
device in an inoperable state.
Always maintain a stable power supply during the update process.
Never interrupt an update in progress.

xviii Safety Instructions
CAUTION
Risk of damage of electrostatic-discharge-sensitive components
The NAVIGAT 100 contains electrostatic sensitive components.
Electrostatic discharge may permanently damage components.
When servicing the NAVIGAT 100, take considerable precautions to pre-
vent electrostatic discharge. Avoid touching any of the electronic cir-
cuitry.
CAUTION
Risk of loss of parameter settings through software exchange
It cannot be guaranteed that parameter settings in the Manual Settings,
Monitoring and Service Setup menus and the entries made in the Mag-
netic Compass Calibration table are left intact when the software is
exchanged.
Before exchanging the system software, record all parameter settings to
be able to re-enter them manually, if required.
Note
The NAVIGAT 100 provides a serial bidirectional interface for a central
alert management system (CAM) according to specified standards ISO
16328 and IEC 61924-2.
Note
All alerts of the NAVIGAT 100 gyrocompass system are category B alerts
according to IEC 61924-2.
Note
For installation and service procedures of the gyrosphere and gyro-
sphere container, the following separate Installation, Maintenance and
Service Procedures, delivered with the gyrosphere, are applicable:
- 5026-0125-01, for gyrosphere type 3, gyrosphere container mod. 10/3.
- 5000-0125-03, for gyrosphere type 3, gyrosphere container mod. 10/4.

System Description 1-1
Chapter 1: Introduction
1.1 System Description
Intended Use
The NAVIGAT 100 is a digital gyrocompass standalone system for the
maritime navigation of vessels and must be operated only from appro-
priately trained and educated personnel familiar with all mandatory
safety and operating procedures.
The NAVIGAT 100 provides North-speed error corrected true heading
data as well as rate of turn (ROT) data for the navigation of maritime
vessels.
The NAVIGAT 100 is not designed to operate in a dual gyrocompass con-
figuration or as part of the Sperry Marine CompassNet (CN) Heading
Management System (HMS).
Not Intended Use
The NAVIGAT 100 and/or the provided true heading and ROT data of the
NAVIGAT 100 are not allowed to be used for the navigation of inland
water vessels and river boats.
Although the NAVIGAT 100 is a highly accurate system for providing
true heading and ROT data, operators must not rely on it solely as the
only heading source. The plausibility of the NAVIGAT 100 heading and
ROT data and the speed and position input data (as secondary data)
must always be confirmed against all other available aids to navigation.
Since the NAVIGAT 100 system can additionally be used for displaying
secondary navigation data (speed and position input data) generated
from other connected devices, the operator must not take displayed sec-
ondary data for granted and is obliged to confirm the validity of second-
ary data independently.
When navigating in polar waters (according to E190E IMO Guidelines
definition), the heading information of the gyrocompass may become
unstable/unreliable, due to physical principles, resulting in possible
deviation. For safe steering of the vessel in polar waters, the heading
information of the gyrocompass may therefore not be used and heading
information of a GNSS (Global Navigation Satellite System) compass be
preferred instead.
