Newest long-term storage digital sound-recording systems – blackboxes – are being delivered to Russian combat ships, said Yulia Khitrova, representative of Verbal Technology Center (VTC).
"Surface ships and submarines of Russian Navy are being equipped with advanced digital sound-recording systems", she said.
Those are Russian-made devices
P-424M and
P-425M (code name is
Tserber), designed for functioning within on-board comm systems. They are also used by coast services for audio and digital data logging, specified Mrs. Khitrova.
Pilot models of that unique equipment were tested as early as 2001 when 22 cassettes with voice records of SSBN
Kursk crew were picked up from the bottom of Barents Sea, said the representative.
That time only VTC managed to carry out an expertise of damaged cassettes. Decrypted materials were turned over to RF General Prosecutor’s Office; then the company developed original digital sound-recording system for Russian ships.
According to Khitrova, in 2008 Navy commissioned transducer
R-758IS designed for long-term storage of messages in nonvolatile memory.
Besides, experts of the Center developed a transducer which prepares data for transmitting Morse-coded text messages. Successful tests of pilot model of this device were conducted recently at the ships of Northern Fleet.
Previously, VTC designed helium speech decoder to hear distinctly "gurgling" voice of a diver breathing helium-oxygen mixture, informs
ITAR-TASS.
