Abstract:

In this design of a backup control for the OSIS Ocean Surveillance Information System Communication processor, the AUTODINNIDN Navy Intelligence Data Network line disciplines were analyzed and reduced to programmed control logic. The method of approach was developed then applied to the AUTODINNIDN protocol. A definition of state, as used in the context of the thesis, is presented, followed by detailed state transition tables and state diagrams. An instruction set of only three instructions was designed which can accomplish all the necessary tasks of the control logic. This instruction set was then used to program the Receive and Transmit control functions of the OSIS system. An implementation plan is presented to suggest possible ways the control unit can be made operational.
