Evolution of SART Testers

The search and rescue radar transponder (SART) is an important part of the GMDSS intended for locating ship or survival craft at sea when it is in distress. 

SART is a small, battery powered, omni-directional radar receiver and transmitter, it can be detected by ship or aircraft radars operating in the frequency band 9.2-9.5 GHz. On receiving a signal from the radar, the device transmits a series of response signals. These signals will be seen on radar screen as a line of 12 dots extending approximately 8 nautical miles away from the SART’s position along its line of bearing. This unique radar signal is easily recognised and allows the rescue vessel or aircraft to locate the survival craft. 

Evolution of testers for SART

The carriage of the SART on board ships is mandatory, according to IMO requirements. IMO also requires that SART, as a part of the GMDSS, be regularly tested. If the radio survey reveals a malfunction, the vessel may be detained at port.

Why proper AIS testing is so important?

An essential maritime safety tool Automatic Identification System (AIS) serves for exchange of real-time safety and navigation information between AIS equipped vessels within VHF range of each other. This information might be helpful for avoiding hazardous situations at the sea.

AIS transmits a bunch of static, voyage-related and dynamic data which should be encoded properly. It is essential for the accuracy of the information it exchanges. 

AIS Testing

An incorrect or even inconsiderate operation of safety equipment may lead to the accidents like what happened on Mississippi River near New Orleans in January, 2020

Evolution of MF/HF/VHF GMDSS Testers

The MF/HF/VHF radio stations with DSC (Digital Selective Calling) are an essential component of modern communication systems operating within the GMDSS.

DSC is used for initial calling of ship and shore stations for the purpose of further communication by radiotelephone or radiotelex. This system involves the transmission of short formalized messages, represented in encoded form using binary characters in the MF, HF and VHF bands.

Evolution of testers for GMDSS radio equipment

The International Maritime Organization (IMO) requires all GMDSS equipment be regularly tested and maintained. Therefore, the inspection of the MF/HF/VHF radio stations is mandatory. 

Each type of such equipment must meet the requirements of SOLAS, as well as the relevant technical demands and standards. They are developed by recognized international organizations such as IMO, ITU-R.
