Test data link processor

This note describes the MODE-S test data link processor (TDLP), which was developed by the EUROCONTROL Experimental Centre. The TDLP is able to emulate a MODE-S data link processor (DLPU) for test and experiments where a ruggedized and certified system is not required. Being PC based, the TDLP is cheaper and easier to operate and to modify than a DLPU. The TDLP can be upgraded to emulate an aircraft data link processor (ADLP).
