Acoustic Measurement Systems
Even AuSIM's audio simulation is only as good as the model parameters within the simulation. For AuSIM, deriving optimal model parameters begins with studying the acoustic world around us. The AuSIM3Dtm display systems synthesize a virtual aural environment from parameters based on the physical world. But the same techniques can be applied to reverse the process and extract parameters from the physical world to use for later synthesis.

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.
