1 GENERAL DESCRIPTION
The Main parts of the Capsule (Tron S-VDR CAPSULE) are the
EPIRB (EPIRB module) and the S-VDR Server module. The
Capsule is developed to meet the regulations and rules for use on
ships, vessels and life rafts in the maritime service. The Capsule
meets the following specifications for S-VDR and 406MHz EPIRB
for use in search and rescue operations at sea:
• IEC 61996 ed.2
• IEC 61097-2 ed2
• IEC 60945
• C/S T.001
• IMO MSC.163 (78)
• IMO A.810 (19)
• MED 96/98/EC
1.1 EPIRB MODULE
The Capsule is buoyant, and is designed to automatically release and to
automatically activate the EPIRB in case of an emergency where the
Capsule and its bracket is submerged into the sea. The EPIRB can also
be manually operated. One mounting bracket is available to mount it as
an automatic and manual EPIRB. The purpose of the EPIRB is to give
a primary alarm to the search and rescue authorities. The EPIRB gives
an immediate alarm when activated, transmitting the ID of the ship in
distress. The EPIRB will at the same time transmit the position of the
ship. Care must be taken not to activate the EPIRB unless in an
emergency situation, in such cases the user will be held responsible.
For periodic testing a test function is implemented. During the test
cycle the EPIRB does a self-test off the transmitters and the battery
status. No emergency signal is transmitted during the self-test. The
battery of the EPIRB will last for at least 168 hours from activation.

1.1.1 System description
The COSPAS/SARSAT system was introduced in 1982 as a
worldwide search and rescue system with the help of satellites
covering the earth’s surface. Since the introduction of the system
more than 11200 persons have been rescued by the
COSPAS/SARSAT system. Currently the system consists of 8
different satellites in a polar orbit Constellation. These satellites
cover the entire earth’s surface and receive the emergency signal
from the 406MHz transmitter within the EPIRB. In addition several
geostationary satellites are equipped with a 406MHz transponder.
These satellites are not able to locate the Capsule but will give an
early warning to the rescue forces, minimizing the time from an
emergency occurs till the rescue forces are at the site. Each
emergency EPIRB in the system is programmed with its own
unique code, therefore it is vital that the ships data that is given to
the dealer you obtained your Tron S-VDR CAPSULE, is correct. If
the EPIRB is programmed with serial protocol, it is important that
the EPIRB is registered in the database for each country. This
database is normally located in the same country that the ship is
registered.
1.1.2 Signal detection
When the EPIRB is activated (manually or automatically) it
transmits on the frequencies 121.5MHz and 406.028MHz.A
homing signal is emitted on 121.5MHz and a burst is transmitted
on 406.028MHz every 50 second after activation. This burst
contains all necessary information about the ships in distress. After
the EPIRB is activated, the next passing satellite will detect the
transmitted signal and relay it to an antenna at a ground station,
called a LUT (Local User Terminal). For the 121.5MHz signal the
satellite must be within line of sight of both the EPIRB and a

82310_UM_ SVDR_E 11
ground station. The ground station or LUT has a 2500 km satellite
reception radius centered at the LUT. In areas without LUT
coverage (mostly less populated areas in the southern hemisphere),
signals from the 121.5MHz transmitter will not be detected by the
satellites, only by passing aircraft’s. From the year 2006,no new
satellites will be launched including 121.5MHz receiver, and from
the year 2009,satellitedetection of the 121.5MHz EPIRB is
terminated. This is not the case with the 406MHz transmitter,
because the satellites have a memory unit, which stores the signals
for relay to the next available LUT giving it a truly global
coverage. Once the signal is received by the LUT, it is processed
for location and sent to a Mission Control Center (MCC).The MCC
sorts the alert data according to geographic search and rescue
regions and distributes the information to the appropriate Rescue
Co-ordination Center (RCC), or if outside the national search and
rescue area, to the appropriate MCC that covers the area that the
distress signal was detected. The RCC in turn takes the necessary
action to initiate search and rescue activities.
1.1.3 Distress location determination
The location of the distress signal is determined by taking
measurements of the doppler shift of the EPIRB frequency when
the satellite first approach and then pass the EPIRB. The actual
frequency is heard at the time of closest approach (TCA). Knowing
the position of the satellite and using the received doppler signal
information, it is possible to determine the location of the Capsule
from the satellite at the TCA. At the LUT, actually two positions
are calculated. One is the actual position (A) and the other is the
mirror image (B) position [FIG.1.1.3]. A second satellite pass
confirms the correct location (A).With the 406MHzsystem the real
solution can be determined on the first pass with a reliability of
nearly 90% and down to an accuracy of less than 5 km (3.1 miles).

1.1.4 Added value in the EPIRB
The EPIRB module has been designed to operate with the
COSPAS-SARSAT system and will enhance further the lifesaving
capabilities of conventional beacons. An integrated 12 channel GPS
module accepts continuous positional information from the
standard GPS system using 27 satellites providing an accuracy of
approximately 100m.Upon activation of the Capsule in an
emergency situation the positional information is incorporated into
the distress message transmitted to LUT.
The main advantage with integrated GPS in the EPIRB is the rapid
response and positional accuracy providing vital information during
a rescue operation practically eliminating valuable time spent
searching for the distressed. Whenever a distress message
transmitted by the EPIRB is detected by a polar orbit satellite
(LEOSAR) the delayed alert remains the same as for non-GPS
integrated EPIRB`s (max.90 min.), but the position accuracy is
improved considerably from a radius of 5 km. to amazing 100m.
Whenever a distress message transmitted by the EPIRB is detected
by geostationary satellite (GEOSAR) the alert is immediate (max.5
min.), still providing the accurate position of 100m. Please note
that the positional accuracy delay is depending on the actual
protocol used and programmed into the EPIRB and the location of
the emergency. The information is based on the capacity of the
LEOSAR/GEOSAR COSPAS-SARSAT system.

14 82310_UM_ SVDR_E
1.1.5 EPIRB registration
Normally the MCC will contact the vessel or the contact person
registered in a shipping register and/or an EPIRB register (Ships
owner, family member etc.) before alerting the RCC. This is to
determine if the alarm from the EPIRB for some reason is a false
alarm, and an expensive rescue operation can be avoided.
Because of this it is important that the ships data is correct in the
shipping register or in the EPIRB database. The Capsule purchased
in some countries will have a registration form attached to it, it is
important that this registration form is completed by the owner and
returned to the place the Capsule was purchased or to the address
specified on the registration form.
Other countries use the already available shipping register to obtain
the necessary information for a vessel in distress, in these countries
the ship is already registered and no registration form is necessary,
however it is vital that the coding of the EPIRB is kept up to date
with data on the ship (nationality, call.sign, etc.), to minimize the
time from an alarm to the start of the search and rescue operation.
Reprogramming the EPIRB can be done at authorized Jotron AS
agents in more than 250 different places throughout the world. If
you are a resident of the United States, you must register this
beacon with the National Oceanic and Atmospheric Administration
(NOAA) using the registration card included with the unit. Fill out
the form and send it to: SARSAT Beacon Registry, NOAA-
SARSAT, E/SP3, FB4, Room 3320, 5200 Auth Road, Suitland,
MD 20746-4304 Vessel owners shall advise NOAA in writing
upon change of vessel or EPIRB ownership. Transfer of EPIRB to
another vessel, or any other change in registration information,
NOAA will provide registrants with proof of registration and
change of registration postcards.

1.2 S-VDR SERVER MODULE
The S-VDR Server module consists of S-VDR Server module house
including Flashdisc. The S-VDR Server module is DC powered from
the ship via the bracket connector. The S-VDR data is fed from the
ships S-VDR system to the S-VDR Server module through the same
connector. When the Capsule leaves the automatic release bracket, all
electrically power and data connections between the ship S-VDR
system and the S-VDR Server module inside the capsule is broken.

3.1.3 EPIRB module
The EPIRB module consists of four printed circuit boards, which
are mounted in the upper housing:
1. The main board w/GPS patch antenna, Xenon flash and an
indicator LED
2. Antenna board. (121.5 / 406 MHz)
3. GPS interface board
4. GPS receiver
For automatic activation of the EPIRB module, put the capsule in
the upright position into the water, and the transmission starts when
the seawater completes the circuit between the two external
electrodes (sea water contacts).
When the capsule is mounted in the automatic release bracket
mechanism, there is a safety switch in the EPIRB module, a reed
contact activated by a magnet at the FBR-3 bracket, which disables
the seawater contacts. See figure 3.1.5.
If submerged in water, the hydrostatic release mechanism will
release the capsule at a depth of 2-4 meters. The transmission will
start when the circuit between the seawater contacts is closed and
the capsule is out of the bracket.
The EPIRB module may be manually activated with the main
switch, and is then independent of seawater contacts. The EPIRB
module will also operate while placed in the bracket when
manually activated.
The capsule may easily be released from the mounting bracket
manually.
