Engineering Device Specification for Phase Computer Module for Use in Project Mohole Ship Positioning System

摘要

This specification covers the detail design, documentation, and fabrication of a phase computing module for use in the Project MOHOLE Phase Comparison System. A module is defined as a self-contained package containing all electronic and electromechanical components necessary to perform the functions described in this specification. The Phase Computing Module will be used to determine the phase difference between two input signals of like frequency and also to perform a system compensating function by addition of a positive or negative quantity to the phase difference measured above.
