What is BS EN 16803‑1 about?
BS EN 16803‑1 addresses the final stage of the performance management approach, i.e., the assessment of the whole Road ITS system performance equipped with a given Positioning System, using the Sensitivity analysis method.
BS EN 16803‑1 addresses the identification and the definition of the positioning performance features and metrics required for Positioning System assessment.
BS EN 16803‑1 gives definitions of the various items to be considered when specifying an Operational scenario and provides a method to compare finely two environments with respect to their effects on GNSS positioning performance.
BS EN 16803‑1 gives a definition of the most important terms used all along with the document and describes the architecture of a Road ITS system based on GNSS as it is intended in this standard.
Note: BS EN 16803‑1 does not address:
- The performance metrics to be used to define the Road ITS system performance requirements, highly depending on the use case and the will of the owner of the system
- The performance requirements of the various kinds of Road ITS systems
- The tests that are necessary to assess Positioning System performances (Record and Replay tests for this purpose will be addressed by EN 16803-2 and EN 16803-3
Who is BS EN 16803‑1 for?
BS EN 16803‑1 on use of GNSS-based positioning for road Intelligent Transport Systems is for:
- Google maps developers
- Road safety department
- Entities dealing with land surveying
- Law enforcement authorities
- Land developers
- Roads and highways authority
Why should you use BS EN 16803‑1?
When a Road ITS system needs GNSS positioning, there is the question of the choice of the type of terminal or of its minimum performances that are necessary to satisfy the system's final requirements at the user level. To meet these requirements, the system includes a processing module called the Road Intelligent Transport Systems application.
BS EN 16803‑1 carries out an assessment of the whole Road ITS system performance equipped with a GNSS Positioning System, which uses the outputs (PVT = Position-Velocity-Time) of a positioning system to provide you the service with a given End-to-end performance.
BS EN 16803‑1 stipulates performance requirements for the global navigation satellite system, which are generally stated as requirements on the outputs of a given system component, assuming that the other components feeding it with input information do respect their own performance requirements.
BS EN 16803‑1 characterizes the performance of the positioning terminal in terms of different features, which enhances the system accuracy, integrity, availability, continuity, and timing performance for better functioning.
What’s changed since the last update?
BS EN 16803‑1:2020 supersedes BS EN 16803‑1:2016, which is withdrawn. BS EN 16803‑1:2020 includes some technical changes with respect to the previous edition.
