Scope of this NWI is to give keys and to propose methods to GNSS-specialized laboratories, enabling them to design and produce valuable scenario using the "record and replay" technique in order to assess GNSS-based positioning system. Already published parts (1-2-3) are mainly dedicated to respectively : -Definitions and system engineering procedures for the establishment and assessment of performances -Assessment of basic performances of GNSS-based positioning terminals -Assessment of security performances of GNSS-based positioning terminals Part4- Definitions and system engineering procedures for the design and validation of test scenarios- will be based on outcomes from GPSTART2 (SA-CEN/2018-12) which was funded by EC to tackle this specific focus (among others).
