Congratulations on your purchase of 3()0-!4% $'03 .AVIGATOR

'. -+)) - an advanced navigation and high performance positioning tool for the professional fleet ....and yet uncomplicated to operate.
The GN30 MKII has a 6" large bright 4 level monochrome LCD display. The latest GPS receiver technology and built-in differential* receiver ensures optimum accuracy at all times. Two units can be
connected together forming: The Bridge System ... one at the chart table for planning and the other at the helm for navigation. Waypoints
and routes are transferred from planning to helm via a high speed data
link.

3HIPMATE '. -+)) IS AVAILABLE WITH OR WITHOUT DIFFERENTIAL '03

4HE 'LOBAL 0OSITIONING 3YSTEM is rapidly becoming the most common
system used for navigation and positioning all over the world.
Not only for maritime use, but also for land-based applications and
aviation.
The satellite-based system has been developed and is operated by the
US Department of Defence in order to provide an accurate and reliable
service, which include a 24-hour global coverage.
The GPS system consists of approx. 24 satellites which orbit around
the Earth at an altitude of approx. 20,200 km.
The satellites transmit perfectly syncronized data. However, depending on the position, the signals will reach the receiver at a slightly different time. By adding the measured time difference to the known
position of the satellites it is possible to calculate the ships position to
within a few meters.
(OW TO USE THIS MANUAL
It is a good idea if you make yourself familiar with the key functions
and menu structure described in chapter 2 before you start out, and
then proceed with section 2.2 Getting started.
F See also Appendix A, Glossary of terms for description of abbreviations, etc.

3ERVICE The GN30 MKII is sealed and does not contain any user serviceable parts. Opening of the unit will void its warranty. Touching
electrical parts inside may cause bodily harm or death. If the unit is not
working properly, please check section 7.7 Troubleshooting. If your
GN30 MKII requires servicing or repair, cal your authorized SIMRAD
dealer.
0OWER SOURCE FUSE AND POWER CABLE Check that the DC power supplied to the unit is within the range of 10 to 32 volts. Note that the apropriate fuse must be employed (see the fuse rating in section 7.4
Electrical connections. Ensure that the power cord is firmly attached.
'ROUNDING To ensure optimum performance of your equipment and
to reduce electrical interference and risk of electrical shock, you need
to properly ground the unit to the ships ground, using the ground
screw on the back of the unit.

having explored the setup functions, you can

by the user to suit individual needs see section 5.1.1 Navigation setup.

 #HARTCURSOR NAVIGATION

To start the chart/cursor navigation will require that the
cursor is already activated in the chart display. If you
currently have a chart display on the screen, all you do
to activate the cursor is press the cursor key. And if
your current display is something different than the

The antenna must be placed in a position where tall
constructions, steel wires, masts, etc. do not obstruct
the view to the satellites. Do not, however, mount the
antenna in the top of a mast or tower, as this may degrade the COG and SOG readings, especially if DGPS
is used. Do not place the antenna close to sources of
electrical interference, such as radar, satcom, etc.
If installing the GPS antenna close to other antennas it
must be placed either above or below the radiation
beams. There is full coverage down to 20 below the

 0OWER SUPPLY CONNECTIONS

The internal voltage regulator will allow the GN30 MKII to operate normally over the power supply voltage range from 10 to 32 Vdc. Connection between the GN30 MKII and the external power supply is
accomplished by means of the supplied power cable, which is approximately 1.5 meters long.
After connecting the cable to the power source, push the plug as far as it
will go into the two pin receptacle marked PWR on the rear of the cabinet and turn the plugs coupling ring clockwise until it makes a click.
The use of longer cable runs, while possible, always increases the likelihood of increased interference and decreased performance. Care must be
taken when increasing the cable lengths to ensure that proper, adequate
and consistent shielding is maintained, that cable of adequate cross section is used, and that all connections are properly made and protected
from the effects of the marine environment.
 &USE
Warning! A fuse should always be installed to protect the unit.
Using a fuse which is not specified for your equipment can cause it to
blow the instant the GN30 MKII has been switched on or it will not protect the equipment as intended.

The unit is preset to receive 19000 pulses per nautical
mile from the log transducer (paddle wheel). However,
the figure might have to be changed to compensate for
various transducers and actual waterflow passing the
transducer. The correct pulse rate is calculated by:
19000 x indicated speed (eg. 4 kn) = 15.200 pulses/nm
actual speed (GPS) (eg. 5 kn)
Measurement units:
NAUTICAL MILE 1 nm is 1,852 metres
KNOTS nautical mile per hour
KILOMETER 1 km is 1,000 metres
kilometer per hour
STATUTE MILE 1 mile is 1,609 metres
mile per hour

Motion

Motion can be set to TRUE or RELATIVE.

TRUE= the ship will move across the chart.
RELATIVE= the ship is locked to the center of the
screen and the chart will move.

Orientation

Orientation can be set to NORTH UP, HEAD UP, or NAV

UP, and the rotation resolution preset to 15 can be set
to adjust the chart for each 5, 10, 15, 20 and 25
changes in present course or heading.
F With cursor on chart, Orientation will always be
presented as NORTH UP.
NORTH UP= will present the chart as north up.
HEAD UP= the chart will automatically turn, so your actual course (COG) is up. If a compass is connected, the
reference will automatically change to heading (compass).
NAV UP= the chart will automatically turn, so your
bearing to destination is up.

Position

Display position as LAT/LON, Loran C or decca lanes.
