Assessment of GNSS-based equipment in the context of AEBS-UNECE R152

With regulations in the areas of the pan-European-eCall, EETS and digital tachograph, obligatory requirements for GNSS-based in-vehicle systems are mandated. Similar is specified in the field of driving assistance, e.g. UNECE-R152. Conformity is verified in accredited laboratories. In each laboratory, the calibration of measuring instruments is essential for testing reliability. Since GNSS observations of such instruments are not directly traceable to SI units, an assessment, validation and qualification must be performed. For this, NavCert developed a procedure based on existing standards. The core is performance verification. An exemplary assessment of the PVT solution is presented here.
