OVERVIEW

MATS3G is a single solution for all underwater communication needs.

MATS3G is the underwater acoustic modem that leverages Digital Signal Processing technology to ensure reliable, long-range communication.

MATS3G series is defines by high, medium, low or ultra low frequency module, Long-range solution (MATS3G-12kHz) up to 15 Km or high-speed solution (MATS3G - 34kHz) up to 24.6 kbps.

Sercel can answer to specific demands and customize MATS3G technology depending on needs.

VITAC from Sercel  is a software module which improves and facilitates image transmission. Even if transmission errors occur, VITAC ensures that transmitted images can still be visualized. Typical compression rate: 20 (24-bit image).

TRIDENT from Sercel is a string of four hydrophones which improves the high-data-rate communication in horizontal channels (shallow water) and noisy environments. Trident manages the processing of multipath spreading for an improved signal-to-noise ratio. Signal-to-noise improvement: 6dB
