Company "Communication&Radionavigation SPb" has been authorized to conduct inspections of shipborne navigation and radio equipment from the following world recognized communities:
  • The Russian Maritime Register of Shipping (RMRS) with permission to issue documents in accordance with form,
  • Russian River Register (RRR) with permission to issue documents in the form of RSI-1,
  • Bureau Veritas (BV) with the permission to issue documents BV,
  • Det Norske Veritas and Germanischer Lloyd (DNV and GL (with permission to issue documentation F440E and F441E)),
  • Lloyd's Register of Shipping - check and installation of equipment, supply of spare parts.
  • Registro Italiano Navale – RINA - Testing of radiocommunication equipment, AIS and Annual performance testing VDR and S-VDR.
Specialists of our company provide:
  • Carrying out inspections of radio equipment for sea and river vessels, drilling rigs and on stationary offshore platforms (verification is carried out for compliance with the requirements of the SOLAS-74 Convention);
  • Inspection of GMDSS equipment;
  • Survey;
  • Annual inspection of the ARB of the COSPAS-SARSAT satellite system (with the issuance of Shore maintenance certificates);
  • Annual testing of Radars;
  • AIS check,
  • Verification and replacement of GMDSS batteries and portable VHF radios.
Checks of ship radio equipment and survey are carried out by specialists who timely consult with leading world manufacturers. During the tests, high-precision and modern equipment is used.

There are 4 GMDSS regions:

  • A1 - in the zone of on-shore VHF radio stations with DSC (approximately 20-30 miles from the coast station).
  • A2 - in the range of onshore radio stations with DSC + A1 (approximately 150 miles).
  • A3 - in the area of ​​operation of the INMARSAT + A1 and A2 system (to about 70 degrees north and south latitude).
  • A4 is the remaining area outside the A1, A2 and A3 areas.
The company Communications and Radio Navigation is approved for testing equipment on ships from six classification societies - 
Russian Maritime Register of Shipping (RMRS)
Russian River Register (RRR)
Det Norske Veritas and Germanischer Lloyd (DNV and GL)
Bureau Veritas (BV)
Lloyd's Register of Shipping
Registro Italiano Navale – RINA

  • Inspections and testing of radio equipment on board ships or floating drilling rigs and offshore fixed platforms for compliance with the requirements of the SOLAS-74 Convention (preliminary survey of radio equipment) with the issuance of acts of Form for RMRS.
  • Checking radio and navigation equipment, in accordance with the rules and requirements of the Russian River Register with the issuance of acts of the RSI-1 form for the RRR.
  • GMDSS Radio Installation Survey (Initial, Periodic, Renewable), in accordance with the provisions of the International Convention for the Safety of Life at Sea, 1974. With the issuance of acts of forms F440E and F441E for GL.
  • Survey radio and navigational safety equipment on the vessel with the issuance of acts of form BV.
Survey is carried out by specialists trained by leading equipment manufacturers.
To check the equipment is used high-precision and modern equipment, passing annual verification and calibration.

Annual check of EPIRB, SART, AIS, VHF of portable radio stations for rescue equipment, GMDSS batteries.


Emergency Position Indicating Radio Beacon are mandatory in any GMDSS navigation area.
EPIRB can be of two types - free-floating and not pop-up. Free-floating are used on all types of ships as part of GMDSS equipment. Non-pop buoys are used as additional or extending the navigation area (for example from A3 to A4).
Our company has the approval of the classification societies and the majority of manufacturers of emergency beacons for the annual comprehensive testing of the EPIRB satellite system COSPAS-SARSAT. Together with the certificate of annual comprehensive verification, a printout of the EPIRB test is issued, indicating all the data taken.
Also, we are entitled to replace the batteries and issue 5-year certificates of Coastal Technical Service (Shore maintenance) of the COSPAS-SARSAT satellite EPIRB system. This operation is carried out in specially equipped rooms where leak testing and operability are checked when sending combat and test signals, while characteristics are removed and issued with a certificate of five-year verification.

SART (Search and rescue radar transponder) are part of the GMDSS to ensure the search for a vessel in distress or a vessel (raft, boat). The respondent triggers upon exposure to a 3-cm radar (X-band) in the range of approximately 8 n miles. Each time a radar signal is received, the transponder emits a series of response pulses, the frequency of which periodically varies over the entire radar frequency range. When activated, the SART first quickly (within 0.4 μs) runs through the range, after which it starts a relatively slow (for 7.5 μs) reverse transition to the initial frequency.
The batteries that ensure the operation of the SART must be changed on time (in accordance with the manufacturer's label, but not later than every 5 years).

Automatic Identification System (AIS)

The Marine Automatic Identification System (AIS) is a position notification system and a system for reporting ship information. It allows ships equipped with AIS to automatically exchange information dynamically and regularly update data on their location, speed, course, etc. (For example, data on the ownership of the vessel) with vessels equipped in a similar manner. The location is determined using GLONASS or GPS systems and the communication between vessels in the VHF band.
Inspection of AIS equipment is performed annually with devices that measure the output signal power, the sensitivity of the receiving signal, the test message of the AIS message and the analysis of reception of data on the vessel.

VHF portable life saving radios

Are on board and provide communication on the range of VHF (marine). In an emergency, backup batteries are opened and installed in the station, which is necessary to maintain communication for a long time in the event of an incident.
The radio stations are checked every year by specialized equipment that calculates the frequency deviation and the output power.
Emergency batteries are stored in accordance with the manufacturer's label, but no longer than 5 years.

GMDSS batteries

GMDSS batteries serve to provide power to the GMDSS equipment when the main board is disconnected. If there is an Emergency Diesel Generator on the ship, then the period for providing power to the equipment must be at least 1 hour; if there is no EDG, the batteries should provide GMDSS equipment with power for at least 6 hours.
The verification is carried out annually with the measurement of the residual capacity, the density of the electrolyte and the full discharge / charge cycle. The GMDSS power transfer system is also tested from the primary to the back side. According to the rules, the transition must be accompanied by a signaling of the light and sound type.
