Cospas-Sarsat Distress Signal Fixed Receiver (hereafter as Sarsat Beacon Monitor 406 – 406MHz emergency radio beacon monitoring system) is intended for 406MHz emergency radio beacon signals reception, decoding and positioning.

This equipment is meant to be used by seaport services, rescue marine centers, coast guard rescue centers or GMDSS rescue coordination centers. SBM 406 is a wide range ground COSPAS-SARSAT signal receiver which allows to locate emergency rescue signals sent by any 406MHz beacon in local responsibility area. Software support allows to observe distress signals and beacon position data on any PC.

SBM 406 provides signal monitoring and processing of the following devices: EPIRB, SASS, PLB.

Effective use

This system has various prospective effective use fields.

Integrated rescue operation facility

The device can be used as integrated rescue operation facility in case of distress to reduce the rescue operation time.

System reduces the emergency signal reception and processing time in coast guard rescue service responsibility local zone and, by means of AIS system integration, displays the received signal with distress positioning on PC. In such a case operator quickly observes the nearest vessel in local zone that is able to render assistance and requests for help.

Rescue operation by SARSAT Beacon Monitor 406

The emergency signal will be received directly and immediately.

This allows to receive signal 5 to 30 minutes faster than by satellite channel path and to start the rescue operation immediately.

Even if take into account that main navigational areas are overlayed by GEO satellites and distress signal is received at first message the time lag nevertheless will be about 5-10 min, or up to 40 minutes near equator. As the device has AIS signal receiving system it is obvious that center operator immediately sees the distressed object nearest vessel and gives instructions for vessel rescue operation via VHF connection.

Certification and check system

The device allows to carry out the annual or regular EPIRB operation check procedure in volume of IMO requirements by reception and check of all beacon’s parameters.

SBM 406 allows to check EPIRB on air that clearly demonstrates and confirms product operation and saves IMO required annual test time for the shipowner. Port authorities are able to issue EPIRB operation check certificate by themselves and to contribute it to the port facilities cost.

Sarsat Beacon Monitor 406 allows to locate and process all false emergency signals on local area and gives the right to port authorities to contribute penalty charges for false distress signal in accordance with Cospas-Sarsat recommendations.

Complete set

System includes main data receiving unit, antenna cable and fixed antenna for outdoor attachment. Main unit can be connected to PC by means of USB cable. Specifically developed software runs automatically for further data processing. System receives and decodes all the Cospas-Sarsat signals.

The standard complete set includes the software which allows to display the beacons with built-in GPS on most marine cartography solutions. The advanced set has AIS receiver and software for data processing received from vessels equipped with AIS (class B and A).

System provides the possibility to create a receiver’s network using Internet protocol for wide area network covering.
