Digital acoustic command system

Summary form only given. With the increasing offshore activity in the scientific and commercial exploration of ocean resources, the requirement for more secure and reliable acoustic command and communication links places ever more stringent requirements on technology. This rationale led to the development of the InterOcean Digital Acoustic Command systems. By employing state-of-the-art techniques from data processing and data communications, and considering both hard wire and RF types of coπrnunication links with their attendant capability of error detection and error rate prediction, an optimally reliable and secure command system has been developed.
