The main purpose of the Galileo 2nd generation advanced PRS testbed (G2G advanced PRSTB) is to develop all classified and non-classified tools that are required to test and confirm the correct implementation of all end-to-end (EtE) G2 PRS and related security functionalities. This activity addresses the development of the G2G PRSTB tools and their integration into a single G2G advanced PRS testbed containing all new PRS capabilities (defined as those new with respect to G1G), namely, the enhanced L-PRS and A-PRS.
