ITS-S unit

instance (3.1.15.3) of an physical unit produced by an ITS station (3.2.7.3) implementation (3.1.15.2)

NOTE: This is a clarification of the definition provided in ISO 21217:2020. While the definition for ITS station unit in ISO 21217:2020 refers to an implementation, the full text interchangeably describes it as an implementation or a physical instantiation, but does not define those terms explicitly.

skos::historyNote Introduced in ISO/TS 14812:2022; revised in 2025. The original definition
resulted in confusion as to whether it was intended to reference merely an implementation,
which is an instance of a realization (e.g., something with a model number) or an instance
of an implementation (e.g., something that would have a serial number). Added Note 1 to
entry.
