With the multiplication of GNSS and the increasing complexity of the new GNSS applications, such as LocationBased Services applications, it will be essential in the coming years to have access to receivers test benches providing a series of test procedures being reproducible and standardized, enabling localization performance assessment. GNSS receiver test benches have to fulfill a twofold need: first, to provide a standardized methodology to enable comparison, in various controlled conditions, of different products that seem to have similar performance specifications on paper. And secondly, to provide a platform to test the functions of receivers in conditions closed to the real targeted environment.
