AUV Communications System Evaluation

Abstract

This document presents the results of investigation into the performance of the model ATM850 underwater acoustic telemetry link. The objective of the research and evaluation program was to evaluate the units on the basis of their suitability for use in an autonomous underwater vehicles (AUV) communications system. The specific type of data presented in this report is the measured bit error rates (BERs) for the ATM850 Link at various ranges and in various operating scenarios. Evaluations were performed using a pair of prototype units. The transmitter was a Datasonics model ATM 850. Both units had omnidirectional transducer configurations with a source level of 178 dB referenced to 1 microPascal at 1 meter. Datasonics is reportedly able to achieve a source level increase of 12 dB by using a directional transducer configuration. The model ATM850 advances the state of the art in underwater acoustic telemetry through the use of imbedded digital signal processing hardware and software. At the present time, the unit is capable of a transfer rate of 1200 bits per second.
