Acoustic Compound Protection System
ACOMPRIS
Static kind of infrastructure is often vulnerable to attacks by either small arms fire (SAF) or mortars. The objects could be for instance a military forward operating base, an embassy or a post from the United Nations. As attacks may occur all the time, persistent and affordable protection is required. Especially when inhibited by civilians, ease of operations use and maintenance become more important. Often installed in remote places far away from the electricity grid, power consumption is an issue.

Acoustic Modem Option for Control Module
Gavia AUVs can be fitted with the Teledyne Benthos ATM-900 Acoustic Modem. The ATM-900 Series Acoustic Telemetry Modem is the most advanced, multipath and noise tolerant, modem available. They are designed to meet both the high data rate requirements of commercial users, and the higher reliability, lower data rate requirements of the military. The modems employ two modulation techniques: phase shift keying (PSK), which provides the highest bit rate, and multiple frequency shift keying (MFSK), which provides reliability in a multipath environment, or when the modems are required to operate in a low signal-to-noise (SNR) environment. The ATM-910 Series can transmit data using PSK modulation for reception by a Gavia Modem Deckbox, but receives data using MFSK modulation only. MFSK modulation is a spread spectrum modulation process that transmits multiple tones simultaneously.
