This document describes a basic role and functional model for mobility services using low Earth orbit (LEO) satellite systems for ITS services. This document provides:

a)       a role and functional model using a LEO satellite system for mobility services;

b)       a description of the concept of operations (CONOPS), and the relevant role models;

c)        a conceptual architecture between actors involved;

d)       references for the key documents on which the architecture is based;

e)       a mobility service use case summary.

In-vehicle control systems are not within the scope of this document.

This document scope is limited to mobility services using physical and digital infrastructure.

NOTE          Physical infrastructure facilities include for example, battery charging facilities, dynamic charging facilities for battery electric vehicles, physical infrastructure markings, physical traffic regulation signs, mobility monitoring facilities, emergency response service support facilities, traffic operation control centre facilities, fee collection service facilities (e.g. road usage fee), battery electric vehicle  charging facilities, online reservation and online mobility usage fee payment facilities, and other infrastructure platform facilities that support ITS mobility services.
