1GENERAL DESCRIPTION
The Tron 40GPS MkII is emergency equipment consisting of:
• Tron 40GPS MkII COSPAS/SARSAT emergency EPIRB
• One of the following brackets:
FB4 - Automatic float free bracket.
FBH4 - Automatic float free bracket v/heating.
MB4 - Manual bracket.
MB5 - Manual bracket.
FB5 - Automatic float free bracket.
The Tron 40GPS MkII EPIRB is developed to meet the regulations and rules for use on vessels and life rafts in the
maritime service. Tron 40GPS MkII meets the following specifications for 406 MHz EPIRBs for use in search and
rescue operations at sea:
IEC 61097-2
IEC 60945
MSC/Circ 862
C/S T.001
IMO A662(16)
IMO A696 (17)
IMO A810 (19)
DIR 96/98 EEC
1.1 TRON 40GPS MkII
The Tron 40GPS MkII is buoyant, and is designed to automatically release and activate in case of an emergency where
the EPIRB and its bracket is submerged into the sea. The Tron 40GPS MkII can also be operated as a manual EPIRB,
by manually releasing it from its bracket and then activating it.
Five different brackets are currently available for the Tron 40GPS MkII. MB4 and MB5 are the manual bracket and
FB4 and FBH4 is the automatic bracket. FB5 is automatic bracket with cover. The manual bracket comes without the
hydrostatic release mechanism and is used to store the beacon inside the wheelhouse or other protected places. The
automatic bracket is mounted in a free space outside where the beacon can be released automatically.
The purpose of the Tron 40GPS MkII 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. 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 on the transmitters and on the battery status.
No emergency signal is transmitted during the self-test.
The battery of the EPIRB will last for at least 48 hours from activation of the EPIRB.

1.2 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 20531 persons have been rescued
by the COSPAS/ SARSAT system (2005). Currently the system consists of 5 functional
satellites in a polar orbit constellation, these satellites cover the entire earth’s surface and receive the emergency signal
from the 406 MHz transmitter within the Tron 40GPS MkII, more polar orbiting satellites will be available in the
future, giving a faster location and rescue time.
In addition several geostationary satellites are equipped with a 406 MHz transponder, these satellites are not able to
locate the Tron 40GPS MkII but will give an early warning to the rescue forces, minimising 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 40GPS MkII, is correct. It is also important that your EPIRB is
registered in the database for each country. This database is normally located in the same country that the ship is
registered.
1.2.1 SIGNAL DETECTION
See figure 7.1.a
When the Tron 40GPS MkII is activated (manually or automatically) it transmits on the frequencies 121.5 MHz and
406.037 MHz. An analogue signal is emitted on 121.5 MHz and a digital signal is transmitted on 406.037 MHz. After
the Tron 40GPS MkII is activated, the next passing satellite will detect the transmitted signal and relay it to an antenna
at a ground station, called an LUT.
For the 121.5 MHz signal the satellite must be within line of sight of both the Tron 40GPS MkII and a ground station.
The ground station or LUT has a 2500 km satellite reception radius centred at the LUT. In areas without LUT coverage
(mostly less populated areas in the southern hemisphere), signals from the 121.5 MHz transmitter will not be detected
by the satellites, only by passing aircraft’s. This is not the case with the 406 MHz 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 Centre (MCC). The
MCC sorts the alert data according to geographic search and rescue regions and distributes the information to the
appropriate Rescue Co-ordination Centre (RCC), or if outside the national search and rescue area, to the appropriate
MCC that covers the area where the distress signal was detected. The RCC in turn takes the necessary action to initiate
search and rescue activities.

18 82823_UM_ 40GPSMkII_E
The International Cospas-Sarsat System will cease satellite processing of 121.5/243 MHz beacons from 1 February
2009. From that date only 406 MHz beacons will be detected by the Cospas-Sarsat satellite system. This affects all
maritime beacons (EPIRBs), all aviation beacons (ELTs) and all personal beacons (PLBs).
1.2.2 DISTRESS LOCATION DETERMINATION
See figure 7.1.b
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 Tron 40GPS MkII 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. A second satellite pass confirms the correct location (A). With the 406 system 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).
1.2.2.1 GPS ADVANTAGE
Tron 40GPS MkII has been designed to operate with the Cospas-Sarsat system and will enhance further the lifesaving
capabilities of conventional beacons. The integrated 12 channel GPS module accept continuous positional information
from the standard GPS system using 27 satellites providing an accuracy of approximately 100m. Upon activation of the
Tron 40GPS MkII in an emergency situation, the positional information is incorporated into the distress message
transmitted to the LUT. The main advantage with integrated GPS in Tron 40GPS MkII 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 Tron 40GPS MkII is detected by polar orbit
satellite (LEOSAR) the delayed alert remains the same as for non-GPS integrated EPIRBs (max. 90 minutes), but the
position accuracy is improved.
1.2.3 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.
Tron 40GPS MkII 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 EPIRB 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

82823_UM_ 40GPSMkII_E 19
the Tron 40GPS MkII 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 Tron 40GPS MkII can be done at authorized
Jotron AS agents in more than 180 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.
