What is the legal Link 16 surveillance track number value range?

The value range for a legal Link 16 surveillance track number is defined as ranging from 00001 to ZZ777. This range includes a combination of numerical digits followed by letters, allowing for a significant number of unique track identifiers. This flexibility helps accommodate the large number of entities that may be involved in a multi-national operation utilizing Link 16 communications systems.

The inclusion of letters in the upper end of the range (from A to Z) after the numerical values allows for a greater variety and extensibility in designating tracks, which is essential in scenarios where multiple platforms and units are operating concurrently. This versatility ensures that each track maintains a unique identifier, minimizing the risk of confusion or overlap in tracking multiple entities within a joint operational environment.
