What is BS EN 16803‑3 about?
BS EN 16803‑3 is the third part of an international standard that covers the use of GNSS-based positioning for road Intelligent Transport Systems (ITS).
BS EN 16803‑3 is a complementary standard to EN 16803-2 that is intended for the assessment of the performances of a GBPT placed in real-life or simulated road environments. It is instead specifically targeting security attacks such as interferences, jamming, meaconing, or spoofing.
BS EN 16803‑3 provides normative information necessary to replay in the lab standardized scenarios specifically dedicated to security tests applied to GNSS. Depending on the case (jamming or spoofing), these scenarios are composed of data sets combining either real-life recorded SIS and jamming signals or simulated SIS and spoofing signals.
Note: BS EN 16803‑3 cannot be applied independently from EN 16803-2 describes in detail the general methodology of the assessment procedure.
Who is BS EN 16803‑3 for?
BS EN 16803‑3 on assessment of security performances 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 16803‑3?
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 16803‑3 deals with the use of GNSS technology in the intelligent transport domain and addresses more particularly the issue of performance assessment.
BS EN 16803‑3 standard proposes a method called “Sensitivity analysis” to assess the adequacy of the GBPT’s performances to the end-to-end performance of the road ITS system. It defines the generic architecture, the generic terms, and the basic performance metrics for the Positioning quantities.
BS EN 16803‑3 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.
BS EN 16803‑3 proposes a complement to this record & replay (R&R) test methodology to assess the performance degradation when the GNSS signal-in-space (SIS) is affected by intentional or unintentional radio-frequency (RF) perturbations. Next sections below stress the importance of this assessment in the context of the security threats.
