0.1 The baseline document to be used for initiation of
the Development Phase of the CAMPS Program is the CAMPS
System Requirements Specification (SRS). The documentation
to be used for the overall system design and subsequent
detailed design, development and testings is described
herein. It is based on ADP Standard 007-3, Issue 2,
14 January 1980, contained in ACE ADP Standards Manual
(AM 96-1-1). It has been modified to include portions
of MIL-STD 490 for hardware and firmware documentation.
0.2 The following contains the Table of contents of the
SDS and in subsequent, sections a detailed description
of the intended content of each paragraph.
