Detailed Objectives: 1. Demonstration of E2E integration of subsystems and their system-level interfaces Successful integration and validation activities, which were already performed for limited system areas and confirmed in SOVT-1, shall be performed for the CPV Phase in a system wide operational context. 2. Identification of timing constraints and data product processing issues Estimated transfer and process times shall be confirmed that are specific to the CPV Phase. Especially the impact of transfer times on the expected start of successive processes. Identification of bottlenecks in system processes, where an underperformance in transfer or in a sub-process causes delays. 3. Validation of Ground Segment stability for 24/5 The complete ground segment hardware, software and communication lines are used in an operational context for 24 hours on 5 days. No forced contingencies are planned, but unexpected outages shall be covered by redundancy. In this case the CPV Phase requirements are more stringent than the routine phase. 4. Validation of Space Segment stability for 24/55 while operating PV phase activities The S/C shall operate for 24 hours on 5 days based upon planned CPV Phase activities. The MTLs shall be executed and the S/C behaviour shall be nominal. 5. Identification of unexpected problems coming up in an E2E operational environment Complex systems conceal unexpected behaviour and this behaviour will differ between the Routine (SOVT-1) and CPV Phase scenario. System wide tests reduce these risks. Ancillary Objectives: 6. Validation of CPV Phase Operations Procedures While most Flight Operations Procedures are validated in SVTs, Ground Operations Procedures shall be validated during SOVTs as well. SOVT-2 is the opportunity to validate CPV Phase procedures. 7. Operational Network under realistic load The measured data transfer times shall confirm the choice of communication lines bandwidths. These times are more stringent during the CPV PhaseELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
