Orbit’s O3b installation is based on OceanTRx™4-500 satellite antenna systems. The O3b
installation is designed to ensure continuous coverage through handover between
operating antennas, as well as robustness through redundancy of operating antennas and
(optionally) a backup antenna and a backup communication room.
The O3b installation consists of either two or three antennas installed above deck, where
usually only two of the antennas operate at any one time - tracking or preparing to track
a satellite. A third (optional) antenna can serve as a backup antenna that (usually) tracks
the satellites as well but only begins transmitting in the event one of the operational
antennas is faulty.
Although antenna handover can be performed according to various, user defined criteria,
it is (by default) performed automatically to provide continuous coverage over the
changeover period of two satellites - one satellite descending and the other ascending, to
compensate for defined blockage zones and for a faulty antenna.
The antennas can be installed at a distance of up to 140 meters from the communication
room located below deck, where data between the antennas and communication room is
transferred over coaxial cable.
The MtsVLink, antenna dedicated management application is used for antenna setup,
management and troubleshooting operations. Once the system is installed and set up,
the O3bLink management application is used for overall system monitoring and if
necessary, for troubleshooting and re-configuration of the handover criteria.
The following figure illustrates the O3b system with three antennas (two operational and
one backup).

The OceanTRx™4-500 O3b system consists of the following main elements:
OceanTRx™4-500 Antenna –either two or three antennas are installed. Two are
operational and a third antenna (if installed) serves as backup.
OSS (Orbit System Selector) –RF switch installed below deck. It is controlled by the
CCU for switching up to 3 systems L-Band Signals.
CCU (Control and Communication Unit) –installed below deck. Provides single source
management and control of the system.

Introduction Antenna Handover

This section describes the default, most common antenna handover configuration and the
options available for modifying the configuration for changing needs.
In most cases, two antennas alternatively transmit to the currently available satellite. In
installations that include a third, backup antenna, the third antenna can either be in
tracking mode (by default) or in stand-by mode - ready to take over in case coverage
cannot be provided by either of the operational antennas.
The antennas track a satellite on its route and ensure continuous coverage by performing
two types of handover:
Planned handover - over the descending time of the current satellite and ascending
time of the new satellite
Mid-pass (unexpected) handover –either when the antenna direction causes the
satellite to antenna path to approach a blockage zone, or if one of the antennas is
identified as faulty and another antenna takes over.
The backup antenna (if installed) takes over only if the currently operating antennas
cannot provide full coverage over existing blockage zones or one of the antennas is
faulty.
The handover criteria and settings are defined by default on the O3b Link application and
can be modified by the user.
1.2.1 Terminology
The following terminology is defined:
Term
Description
Physical names
Antenna-1, Antenna-2, Antenna-3
Primary/Active Antenna
Tracking Antenna which Transmits and Receives and
is connected to the active Demod in the modem.
Secondary Antenna
Tracking Antenna which Receives but does not
Transmits and is connected to the non-active
Demod.
Switching
Primary and Secondary Antennas switch roles
between them at the exact moment of Handover -
Primary becoming Secondary and vice versa.
Backup Antenna
May be tracking mode or in standby mode.
Antenna which does not transmit and is not
connected to any one of the two Demods.
Stand-by Backup Antenna
Antenna which Does not transmit and is not
connected to any of the Demods, but is forced (by
CCU Configuration) to Stand-by mode.

1.2.2 Planned Handover
This section describes the tracking and handover flow of two operational antennas for
ascending and descending satellites. The handover time is planned since the track of the
satellites is known and programmed in the system.
For clarity, the backup antenna is shown as being in Standby mode; by
default, in most configurations the backup antenna tracks the satellites
as well.
A. Both antennas (primary and secondary), track the same descending satellite on its
course.
Figure 1-3: Two Antennas (primary and secondary) Tracking Descending Satellite
B. A set period of time before the planned handover time, the secondary antenna
turns towards the ascending satellite, while the primary antenna continues to track
the descending satellite.
Figure 1-4: Before Handover, secondary Antenna Turns to Ascending Satellite

Introduction Antenna Handover

C. During handover, the secondary antenna (tracking the ascending satellite) begins
receiving and transmitting the signal. The primary antenna (tracking the
descending satellite) continues receiving and transmitting as well. (Each antenna
receives and transmits to a different satellite).
Figure 1-5: During Handover, both Antennas Rx and Tx to Different Satellites
D. After a set period of time (following Step-C), the antennas exchange roles:
oThe primary antenna (tracking the descending satellite) stops Tx and assumes
the role of secondary antenna and turns to the ascending satellite (Rx only).
oThe secondary antenna (tracking the ascending satellite), assumes the role of
the primary antenna.

Antenna Handover Introduction
1-6 OceanTRx™4-500 O3b System Installation Guide
1.2.3 Mid-pass Handover
This type of handover is unexpected and occurs under one of the following conditions:
Antenna to satellite communication path nears a (defined) blockage zone
One of the operating antennas is faulty
1.2.3.1 Handover Due to Blockage Zones
A blockage analysis based on the antenna location and position is performed. As the path
of the transmitting antenna approaches within 30 minutes of the blockage zones,
blockage warnings are displayed at five minute intervals (“Blockage expected in
<30 min”, “Blockage expected in <25 min”, etc.). A short time before the anticipated
blockage, handover will be performed to the secondary antenna; if the secondary
antenna is within a blockage area as well, handover will be performed to the backup
antenna.
Both antennas continue to alternate for continuous coverage. In installations with three
antennas - if both antennas are expected to communicate over defined blockage zones,
handover will be made to the backup antenna.
The system takes into account some angular extension for the defined
Blockage Zones above the ship. This is used to cover for Blockage-
Zone measurement inaccuracies as well as the predicted Satellite path
deviations.
1.2.3.2 Handover Due to Faulty Antenna
If one of the active antennas is faulty, handover occurs to the other antenna. If both
antennas are faulty, handover will be performed to the backup antenna (if available).
A fault condition can also be incurred by one of the following:
LAN communication problems between the ADE and BDE equipment
Incompatible ADE or BDE software version
IMU not locked
Manual modifications of some of the critical operational settings of the antenna
Lock indication from the modem not received –optional and can be changed by the
GUI
1.2.4 System with Only One Active Antenna
It is possible to use the system with only one active antenna, in this case:
The antenna will not switch role when transferring to the next satellite –it will
continue transmitting.
The new satellite selection happens exactly at handover time.
The system periodically checks if there is another antenna that can be used.
