AN/BRN-7Computer Program Specification. Volume III. Synchronization Subprogram Design.

摘要

This volume describes the subprogram to be used by the Submarine OMEGA Navigation System. Subprogram tasks include: (1) Set the antenna switching matrices to proper orientation for the collection of synchronization pulses; (2) Record the computer reference time; (3) Initiate the repetitive 10-second data collection process. Since this is a repetitive operation, alternate 10-second collections must be stored in separate storage areas; (4) After a 10-second data collection period the 100 correlation numbers must be calculated; (5) Test the four largest correlation values to find if synchronization can be determined; and (6) Determine t sub sync.
