What the specification covers
S04P06 supports location tracking for general transport service delivery as well as use cases requiring higher positioning accuracy, such as depot management. It allows different coordinate systems and positioning technologies to be used transparently to deliver location data for a wide range of purposes. S04P06 extends the GNSS-based location interface S04P06N01, released in April 2026.
