Hydrostatic Release Unit G-5

The G-5 Hydrostat is an automatic release device for use with Liferafts, EPIRBs and other equipment.

The Hydrostatic Release Unit G-5 is widely used for Emergency Position Indicating Radio Beacons (EPIRB). Should the vessel sink, the G-5, which is activated by increasing water pressure, will automatically release the EPIRB. On reaching the surface the EPIRB starts to emit a signal of identification and position to a satellite. Instead of the rope sling a specially developed plastic bolt secures the radio beacon and will be cut when the unit is activated.

Hydrostat G-5 is our last development in a field of hydrostatic release devices. This is a so-called collet-type device of proprietary design of the radio communication designing department former engineer Vladimir Shchegolev in agreement with Musson Marine Ltd.

Formerly he had also designed collet hydrostats for ЕВ-10 radio beacon (Saracom Ltd). COSPAS-SARSAT certificate #94 is used in EPIRB EB-20 and EB-20 SVDR Capsule (COSPAS-SARSAT certificate #128). For this СM-511 device two press mold sets are manufactured (made in Korea and Ukraine).

The similar principle of the operation is typical for hydrostats for EPIRB Samyung SEP – 406 certificate #117, SEP-500 and SEP – 500В (certificate #195).

Hydrostat principle of the operation is what the spring within hermetic package fix the collet down. At the bottom of the hydrostat there is non-leaking rubber membrane which pulls off under a pressure of water by means of what the spring constricts, collet pressure grows weaker and the collet jumps out of the case.

According to ОЕМ agreement hydrostat G-5 is used on the following products:

EPIRB M-406 (Yaroslavl radio manufacturing plant, certificate #145)
EPIRB Marlin-406 (Marlin-406 A2) (manufactured by Kolgrim-Don, certificate #161)
EPIRB PRO-5 (manufactured by Uranis, certificate #172)

Other Products

EPIRB PRO-5 Float Free

Pro-5 Float Free Satellite Emergency Position Indicating Radio Beacon (EPIRB) measures up with the IMO requirements for COSPAS-SARSAT system and is a mandatory item in the GMDSS (Global Maritime Distress Safety System). When a distress beacon is activated, it transmits a distress radio signal that is detectable by satellites. The beacon is brought into action automatically to transmit distress signal (position and identity) at depth of 4 meters or more. This equipment guarantees high-speed identification by means of the unique code of each beacon, positioning to within one nautical mile with short response time.

AIS-SART Musson-502A

Our company has developed completely new maritime safety equipment AIS-SART Musson-502A, which is mandatory item to be installed on ship. The AIS-SART Musson-502A operates in A and B VHF channels of AIS (automatic identification system), instead of standard search and rescue radar transponder operating in 9.2-9.5GHz. The new AIS-SART fully corresponds to IMO, SOLAS and GMDSS requirements. AIS-SART Musson 502A uses the built-in GPS module to send messages with coordinates of distress to near vessels' AIS.

Hydrostat for SM-511

Hydrostatic release device for SM – 511 (COSPAS-SARSAT certificate #№ 96) State Designer's Bureau of Radio-communication. Hydrostate for SM– 511-world’s first compatible collet hydrostat for float-free 406MHz EPIRB was designed by department former engineer Vladimir Shchegolev in 1995. This device is complete analog to ЕВ-10 EPIRB’s hydrostats manufactured by Saracom (COSPAS-SARSAT certificate #94) which is also used in EPIRB EB-20, EB-20 SVDR Capsule (COSPAS-SARSAT certificate #182).

AIS Pilot Plug to USB Cable

The AIS Pilot Plug Cable is intended to receive any data from mobile AIS stations Class A or B. It gives the simple way to connect the mobile ship AIS station to your PC, laptop or desktop. The AIS Pilot Plug Cable supports RS-422 and RS-485 interfaces by means of switcher.
