General

In addition to regular Inmarsat-B services, Saturn B equipment with
software for Extended Services provides as follows:

• Inmarsat-B Lease Mode CN17

• Saturn B Enhanced Bitrate Module

Inmarsat-B Lease Mode and Saturn B Enhanced Bitrate Module
are special services provided by some LESOs.

• Saturn Bm Dual Antenna functions

The services are generally operated through global beam of
Inmarsat’s spare satellites (Inmarsat I2 and spare I3 satellites),
however, Saturn B may operate on I3 Spotbeams if allocated.

Inmarsat Lease Mode CN17

Inmarsat offers operation for parties who want to establish closed
network services. CN17 is a system for long term communication.

The Inmarsat Lease Mode CN17 offers the same service (less
Distress) as with Saturn B in Inmarsat Normal Mode.

The Lease Gateway LES generally only offers 16 kbps Voice and
64 kbps High Speed Data services.

Saturn B Extended Services6

Saturn B Enhanced Bitrate Module

Saturn B Enhanced Bitrate Module (EBM) requires installation of
an Interface Converter Unit (ICU) and an External Modem unit.

EBM is a system for long term communication over a leased satellite
channel. Initiation of lease service is by selection of speed, type of
modulation and channel (frequency) both at the MES and LES.

The system is open for operation through Inmarsat’s lease satellites

only.

• For operation, please note that Saturn B needs to be

commissioned for this service.

• If Saturn B is commissioned for Inmarsat normal mode, the IMN

Numbers registered for the terminal remain unchanged for use in
normal mode.

Saturn B with Enhanced Bitrate Module (EBM) offers three different
services:

• Fixed

• Variable Bandwidth System (VBS)

• Variable Bit Rate (CN17Ext)

Fixed

The Fixed service is a manual operation where frequency, speed etc.
is agreed upon with the Lease Gateway LES and set up manually
each time you initiate a connection.

• Saturn B equipment provided with software capability for Inmarsat

Lease Mode Services.

• No extra additional hardware is needed, however, a Lease Mode

Opening Key is required.

• For operation, please note that Saturn B needs to be

commissioned for this service.

• If Saturn B also is commissioned for Inmarsat normal mode, the

IMN Numbers registered for the terminal remain unchanged for
use in normal mode.

Variable Bandwidth System (VBS), and

Variable Bit Rate (CN17Ext)

VBS is a Telenor/COMSAT LES system implementation, whereas
CN17Ext is a Nera/Stratos system implementation. They provide
ship-to-shore and shore-to-ship dial-up service. Selection of speed,
channel etc. is automatic, based on request and available service
(channel/speed).
The systems include frequency management at the LES for optimum
use of leased channel(s). The VBS and CN17Ext systems are based
on extended Inmarsat signalling.
The services are open for operation through Inmarsat’s lease
satellites only.

Saturn Bm Dual Antenna functions

Saturn Bm equipment with Antenna ADE Mk2 version (with electronic
sensors) and CTRL SW Series 7.12 and up, may be modified for
Dual Antenna operation.

Opening Keys

• Opening Key for Inmarsat Lease Mode is required for operation in

Inmarsat Lease Mode and Dual Antenna operation.

• No Opening Key is required for Dual Antenna Operation.

System

A Dual Antenna system comprises two separate Saturn Bm
installations and a Dual Antenna Switch (DAS).
A Rotary Joint Kit, part 101210 is required for both Saturn Bm
Antennas. The Dual Antenna system is only functional for Inmarsat
Lease Mode operations.

The Dual Antenna Switch allows the MCU-A (dedicated as MASTER)
to select one of the two antennas for satellite communication.

Saturn B renter/owner Level

The Saturn B terminals provide the following access levels in addition
to USER (1) level and OPERATOR (2) level:

• RENTER (3), and

• OWNER (4)

The RENTER and OWNER levels are protected by passwords.
The default password for both levels is 1 2 3 4 5 6.

Password protection can be used to restrict operative functions to
different parameter levels, e.g.:

• level 4 (OWNER) allowed to change setup.

• level 3 (RENTER) allowed to read data.

• level 2 (OPERATOR) given no access to reading or setup.

• level 1 (USER) has standard minimum operational functions.

These restrictions can be applied according to function, e.g.:
the RENTER level can be allowed to configure the ASD function, but

restricted to reading only in the access code function.

An individual password may be assigned to level 3 and 4 using the "SET
PASSWORD" function no.13, see the Saturn B Data Service manual.

To set access level:

1

Select SET USER LEVEL function (12):

2 Display the current level:

3 Key in operator level ref. number,

e.g. 3 (RENTER):

3=RENTER, 4=OWNER

4 Key in the current password for this

level (the default password
is 1 2 3 4 5 6):

5

The terminal is now set to RENTER LEVEL:

This level is active until a new level is set or the
terminal is switched off. Therefore, set the level

back to USER when finished with your operations.

and revert to IDLE:

Satellite search levels – Saturn Bm Marine only

The search level used during an Initial Search or an Auto Search is
described in the Saturn Bm Operator’s Manual, see "Satellite

Search" in chapter 2. operation.
The table below describes the search level patterns when operating

in Lease Mode (0,1,2,6 and 7 are optional):

Normal mode

0: NO_SEARCH
No automatic search is performed.

1: AZIMUTH_ONLY

Antenna uses the last known elevation in the
current Ocean Region, and sweeps 360
degrees horizontally for last active NCSC
frequency.

2: ACTIVE_FREQ

Recommended for initial search for Lease Mode
operation.

Antenna makes a hemispheric scan for last
NCSC frequency in the current Ocean Region.

3: REGION_FREQS
Antenna a hemispheric scan for all active NCSC
frequencies in the current Ocean Region.

4: ALL_REGIONS

Antenna a hemispheric scan for last active
NCSC frequency for all Ocean Regions.

5: FULL_SEARCH
Antenna searches whole hemisphere for all
active NCSC frequencies for all Ocean Regions.

6: DIRECT_SAT
Antenna uses heading, position and satellite
position to calculate and point directly to the
satellite for current Ocean Region.

7: DIRECT_BEST
Antenna uses heading, position and satellite
position to calculate and point directly to the
satellite for each Ocean Region, determining
and selecting the best Ocean Region to use,
searching all possible NCSC frequencies.

Lease Mode CN17

Antenna uses the last elevation in
current Ocean Region, and
sweeps 360 degrees horizontally
for selected CESAL frequency.

Antenna searches for selected
CESAL frequency in the current
Ocean Region.

Same as Lease Mode for
ACTIVE_FREQ.

Same as for ACTIVE_FREQ.
