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).

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).

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
