What is BS EN 16803‑2 about?
BS EN 16803‑2 deals with the use of GNSS-based positioning terminals (GBPT) in road Intelligent Transport Systems (ITS). GNSS-based positioning means that the system providing position data, more precisely Position, Velocity and Time (PVT) data, comprises at least a GNSS receiver and, potentially, for performance improvement, other additional sensor data or sources of information that can be hybridized with GNSS data.
BS EN 16803‑2 proposes testing procedures, based on the replay of data recorded during field tests, to assess the basic performances of any GBPT for a given use case described by an operational scenario.
BS EN 16803‑2 addresses the “Replay” part of the test scenario data set.
Who is BS EN 16803‑2 for?
BS EN 16803‑2 on assessment of performances of GNSS-based positioning terminals is useful 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 16803‑2?
It is very important to highlight the standard way to deal with the use of GNSS technology in the intelligent transport domain and more particularly the issue of performance assessment needs to be addressed.
BS EN 16803‑2 proposes a test methodology based on the replay in the lab of real data sets recorded during field tests, assuming no security attack during the test. It also proposes a complement to this test methodology to assess the performance degradation when the GNSS signal-in-space (SIS) is affected by intentional radio-frequency (RF) perturbations, such as jamming, spoofing, or meaconing, also applicable to unintentional RF perturbations.
BS EN 16803‑2 supports EN 16803-4 to propose the methodology for the recording of the real data sets and is targeting mainly the GNSS-specialized test laboratories that will be in charge of elaborating the test scenarios that will be replaced by the previous category of test laboratories. These tests address the basic performance features availability, continuity, accuracy, and integrity of the PVT information, and also the Time-To-First-Fix (TTFF) performance feature considering that there is no particular security attack affecting the SIS during the operation.
