Title

Multi-Sensor Real-Time Data Acquistion and Preprocessing at Sea

Abstract

This paper describes the real-time underway data acquisition system developed by the Shipboard Computer Group of the Scripps Institution of Oceanography in support of seagoing research Since February 1984, this system has been implemented on a DEC VAX- 11/730 computer which runs the UNIX operating system and communicates with various sensors through an IEEE-488 General Purpose Interface Bus and slave microprocessors. The sensors interfaced in this fashion acquire navigation data (i.e. ship's heading, speed and position) and geophysical data (gravity, magnetics, Sea Beam bathymetry and expendable bathythermograph profiles). After a brief overview of the hardware involved, the paper discusses near real-time processing of the underway navigation and geophysical data made available to the investigator during the course of a survey.
