MULTI-SITE INTERROGATION SCHEDULING FOR THE DISCRETE ADDRESS BEACON SYSTEM

A theoretical analysis and computer simulation were undertaken to develop a DABS/ATCRBS scheduling algorithm which would be capable of servicing the projected 1995 Los Angeles Basin (1608 aircraft aloft). A satisfactory technique was found using sub-epoch timing, partitioning between packed and synchro calls, and time-sharing (a separate interval for each site's synchro calla). The technique also provides garble-free Synchro DABS (air-to-air CAS) service in the multi-site DABS/ATCRBS environment. Time is provided during the packed call interval for extended length messages and target reinterrogation. (Modified author abstract)
