Abstract : This report describes the Satellite Vertical Line Array 32 channel system (SVLA-32) developed at the Naval Research Laboratory for use during open ocean acoustic signal processing investigations for remote data collection and system control. This system was used during the TTCP Environmental Signal Processing Experiment (TESPEX) exercises in the summer of 1994, and demonstrated its ability to provide real time collection of acoustic data over 32 channels, to perform onsite data formatting and the satellite transfer of that data to shore, and to allow full system command and control via the same satellite link. The system can be divided into the following subsystems: (1) the in water subsystem: a hydrophone array, data acquisition unit, and umbilical cable, (2) the signal processing and recording subsystem, responsible for data formatting, storage to recording devices, and data dissemination, (3) the satellite communication subsystem, responsible for data telemetry and for remote control of the ocean buoy from the shore data processing center, and (4) the buoy subsystem, which includes a primary power generator and a buoy weather station. Capabilities of the current system are described as well as lessons learned during the TESPEX II program.
