CEN ISO/TS 21176

Cooperative intelligent transport systems (C-ITS) - Position, velocity and time functionality in the ITS station

active, Most Current
Organization: CEN
Publication Date: 1 September 2020
Status: active
Page Count: 38
ICS Code (Transport in general): 03.220.01
ICS Code (IT applications in transport): 35.240.60
scope:

This document specifies a generic position, velocity and time (PVT) service. It further specifies the PVT service within the ITS station (ITS-S) facilities layer (ISO 21217) and its interface to other functionalities in an ITS-S such as:

- ITS-S application processes (ITS-S-APs), defined in ISO 21217;

- the generic facilities service handler (FSH) functionality of the ITS station facilities layer, defined in ISO/TS 17429.

This document specifies:

- a PVT service which, dependent on a specific implementation, uses a variety of positioning-related sources such as global navigation satellite systems (GNSSs, e.g. GALILEO, GLONASS and GPS), roadside infrastructure, cellular infrastructure, kinematic state sensors, vision sensors;

- a PVT service which merges data from the above-mentioned positioning-related sources and provides the PVT output parameters (carrying the PVT information) including the associated quality (e.g. accuracy);

- how the PVT service is integrated as an ITS-S capability of the ITS station facilities layer;

- the interface function calls and responses (Service Access Point - service primitives) between the PVT ITS-S capability and other functionalities of the ITS station architecture;

- optionally, the PVT service as a capability of the ITS-S facilities layer; see ISO 24102-6;

- an ASN.1 module C-itsPvt, providing ASN.1 type and value definitions (in Annex A);

- an implementation conformance statement proforma (in Annex B), as a basis for assessment of conformity to this document.

NOTE It is outside the scope of this document to define the associated conformance evaluation test procedures.
