Warranty Certificate booklet enclosed with the equipment) is signed and returned to Nera SatCom.
Grounding
Grounded AC power socket shall be installed near the equipment and shall be easily accessible.
Connection to all type of equipment meant for operation of the unit must be done while the unit is
powered off.
Cables and connections
Cables must be shielded. The shield must be grounded at both ends.All peripheral equipment must be
grounded.

Be aware that ports configured for telefax service can not be used for telephone (voice).
Power supply
Power supply voltage specification: 220 VAC ± 10%, 50 – 60 Hz.
Operation from 110 VAC is possible with optional transformer.
Operation from 12 – 28 VDC is also possible.
It is strongly recommended that a 24 VDC source of energy is connected to the 220 VAC/28 VDC Power
Supply.
Equipment ventilation
To ensure adequate cooling of MCU and Power Supply a 10 cm unobstructed space must be main-
tained around all sides of the units (except the bottom side).
Ambient temperature range: 0 – 45 °C.
When installed inside rack or locker, the ambient temperature for the MCU shall not exceed 30° C.

Below Decks Equipment – BDE
Main Control Unit
The Saturn Bm Main Control Unit (MCU) – which constitutes the major
electronic part – is designed for wall or desktop installation. The MCU sup-
plies 28 VDC power to the ADE through the coaxial cable. The MCU power
requirement is 200 W at 11 - 34 VDC (12 V or 24 VDC nominal): - standby
3.5 A, high power 6.7 A, medium power 6.1 A and low power 5.3 A.
Display Handset
The Display Handset keypad and built-in display allow dialling and
control of the MCU and antenna.
Distress Alarm
The Distress Alarm Unit provides remote activation of an alert transmission
and indication of incoming distress calls.
Power Supply
The AC/DC Power Supply is designed for 220 VAC (110 VAC by strapping)
and 24 VDC inputs, and provides 28 VDC output.
24 VDC input from battery is recommended to prevent mains drop problems.
Options
• DTMF telephones (max 5)
• Telefax (replacing one of the DTMF telephones)
• Message Indicator, activated on reception of telex, telefax or data traffic
• PC (Telex)
• PC (Data)
• Serial printer

Placing the Antenna
Avoiding obstructions For GMDSS installations
If the installation shall comply with GMDSS in accordance with the interna-
tional standard IEC 61097-10, please note as follows:
It is desirable that the antenna be sited in such a position that no obstacle
likely to significantly degrade the performance of the equipment appears in
any azimuth down to an elevation angle of -5 degrees.
The siting of the antenna needs careful consideration, taking into account
the adverse effect of high levels of vibration which may be introduced by
the use of a tall mast and the need to minimise shadow sectors. Objects,
especially those within 10 m of the radome which cause a shadow sector of
more than 6 degrees, are likely to significantly degrade the performance of
the equipment.
For non-GMDSS installations
The antenna has a beamwidth of 10 degrees and ideally requires a free
line of sight in all directions above an elevation angle of +5 degrees.
Any obstruction will cause blind sectors, resulting in signal degradation or
even loss of communication with the satellite.
Degradation of the satellite signal can only be completely avoided by plac-
ing the antenna higher than any obstructions. This is often not feasible and
a compromise must be made to reduce the number of blind sectors and
cost of installation.
The degree of signal degradation depends on the size of the obstructions;
the distance to them must therefore be considered.
Preferably, all obstructions within 3 m of the antenna should be avoided.
Obstructions less than 15 cm in diameter can be ignored beyond this
distance.
Radiation precautions Passengers should not be admitted in areas closer than 5 m from the
antenna.
However, no restrictions are required when the antenna radome is installed
at least 2 m above the highest point accessible to passengers.
Authorized personnel should not be near the antenna for periods of more
than 1 hour per day without switching off the RF transmitter.

Installation Manual
Saturn Bm PLANNING
Avoiding interference Do not locate the antenna close to interfering signal sources, or in such a
position that the source (e.g. radar-antenna) radiates directly into the Sat-
urn antenna.
The Above Decks Equipment (ADE) should be separated as far as possible
from other transmitters, and preferably by at least 5 m from the antenna of
other communication or navigation equipment, such as the antenna of the
satellite navigator, the VHF antenna or radar equipment.
Compass safe distance For installation on British or Norwegian vessels, the antenna should be
located at a distance of at least 1.0 metres from the magnetic steering
compass. Be aware that requirements may vary from one country to
another.
Other precautions Do not place the antenna close to the funnel, as smoke deposits will then
eventually degrade antenna performance.
Regardless of the location chosen for the antenna, it should point forward
in parallel with the ship’s longitudinal axis when in the middle of its azimuth
range, which will correspond to zero degrees on the azimuth indicator. The
forward direction is indicated on the antenna radome with a heading mark
The antenna should be installed so that severe vibration and shock
are avoided.
If installed on top of a signal and radar mast, the mast must be
supported by stays.
The coaxial cable runs out from the antenna foot in the direction of
the heading mark.

Designing the Antenna mast
The mast must be designed to carry the weight of the antenna unit, approxi-
mately 90 kg. It must be able to withstand wind forces of up to 120 knots on
the radome as well as the onboard vibration levels. The radome is 1.445 m
high and has a maximum diameter of 1.42 m.
The top end of the mast should be fitted with a flange with holes matching the
bolts extending from the bottom of the radome. See figure below. The flange
must not be so large as to interfere with the hatch at the bottom of the an-
tenna unit. The holes through the mast flange must be positioned symmetri-
cally about the ship’s longitudinal axis.
A HEADING mark on the radome indicates the forward direction of the
antenna.
NOTE: If necessary to disalign heading mark, (because of hatch accessibility),
the antenna inside the radome has to be aligned towards ship's heading. This
must be done before fixed to the antenna mast. (Pedestal coax outlet = Ped-
estal heading mark. (See Installation: "Connecting up Above Decks Equip-
ment").
NOTE: On ships with excessive vibration the mast must be supported by stays
or other adequate means. If the height of the mast makes it neces-
sary to climb up to the antenna unit, a
ladder must be provided on the mast
column. A guard rail must be attached to
the upper section for safety purposes. If the
height of the mast exceeds approximately
4.5 metres, an access platform should be
attached to the mast approximately 1 metre
below the radome bottom.
Be aware that requirements may varyfrom
one country to another.
