GeoSpectrum Technologies has launched a Multipurpose Autonomous Sub-Surface Training Target (MASTT) system for submarine detection and tracking training.

MASTT replicates the acoustic signature of submarines for anti-submarine warfare training, from conventional to nuclear with a variety of running modes of operation. In this mode MASTT will transmit fixed frequencies, either independently or when triggered by a received acoustic signal. It can retransmit a synthetic echo of received acoustic signals and a Doppler shift can be also incorporated into the retransmitted echo, increasing or decreasing the intensity of the sound in line with the distance.

The capabilities are available in both medium and low frequency bands. MASTT can operate in different running modes depicting standard submarine movement: moving in a straight line in a fixed course, speed or depth, moving in a zig zag pattern with course alterations, a near stationary mode and a multiple course with speed and depth alterations.

MASTT measures less than 3m in length and a little over 32cm in diameter. The system can be stored on an Mk 46 Mod 5 torpedo rack for quick launch and recovery as well as user friendly deployment for surface ship crew. The system is equipped with rechargeable batteries providing a minimum of eight hour operation endurance at four knots cruising speed and only three-four hour charging time.
