Mode S, or mode select, despite also being called a transponder radar system replacement for Air Traffic Control Radar Beacon System (ATCRBS), is actually a data packet protocol which can be used to augment ATCRBS transponder positioning equipment (radar and TCAS). Mode S is designed to fully interface with ATCRBS systems: mode S SSRs can interrogate ATCRBS transponders, and AIS-P transponders will also reply to older ATCRBS and TCAS interrogations. |
