The G2G System offers new features and user capabilities, such as new signals, new ranging accuracy using ISL, new on-board clock and signal performances, new ways to disseminate the mission products from the point of view of the ground and space assets. A specific test bed is required to analyse these new features as early as they are being deployed. The delivery of this activity will be the G2 System Test Bed developed and delivered in versions, and operated during the activity duration in order to provide inputs to the G2 IOT (In-Orbit Test) and IOV (In-Orbit Validation) tests and report on the performance of the G2 Early Capabilities (for HAS, SAR, EWS, ARAIM and Timing Service Monitoring) and the legacy services. Options will be included for the extension of the maintenance activities.
