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