  2. Ground Stations and Network • Antenna pointing tests carried out with the STARDUST spacecraft on June 07 & June 11, 2002. The New Norcia station successfully acquired the signal from NASA’s STARDUST spacecraft currently 2.1 AU away from Earth. • System test activities of the Antenna Front-end are about to be completed. Projected completion is 04-Jul-02. • Combined Front-end / Back-end testing (04/25-July-02). • Formal station hand-over test (29-Jul / 06-Sep) with hand-over to operations early September 2002 (L-4 months). • New Norcia & DSN Tracking campaign with Ulysses 17/23-Sep-02.

  3. Mission Control System / Simulator Mission Control System • DDS - PI interface testing and load test revealed shortcomings (performance and robustness); • RMCS/SCOS-2000 "load test" gave some hints on persisting problems with retrieval performance. • Delivery C.2 of Rosetta Mission Control System made 28-May-02. Delivery D (05-Aug) and Delivery D1 (02-Sep-02) and D2 (03-Oct-02) are planned. Simulator • Delivery D2.3 made 17/23-May-02 showed improvements (runs latest on-board software). • Delivery 3.0 planned 10-Jun-02 and final version 3.1 planned for 17-Jul-02, marginal for start of simulations campaign.

  4. Flight Dynamics / Mission Analysis • System tests have started, whereby tests of pre-launch subsystems initialization (Init) and LEOP sequence has been performed; • Flight Dynamics participation in LEOP SVT-0/4 (provision of commands / monitoring of telemetry) completed; • Collaboration/consultancy on interplanetary navigation with the Navigation Section at JPL continues to progress very well. Recent meeting 21/23-May-02. Exchange of pointing angles for Ulysses successfully completed; • Consolidated Report on Mission Analysis issued April 2002.

  5. Mission Operations Preparation • Acceptance test activities are continuing for the simulator and mission control system; • Flight Operations Plan (FOP) issue 1.1 released mid May; • SVT-0/3 : On-Board Software debugging / validation successfully completed (PROM software burning); • SVT-0/4 : LEOP and AOCS closed loop completed; • PFM SVT-1/1 ongoing with emphasis on payload; • SVT-1/2 (06/08-Aug-02) agreed with project office; • SVT-2 (05/10-Nov-02) conducted remotely from ESOC - PISA.

  8. Principal Investigator Schedule of Events

  9. PI/Lander Operational Interface Concerns • Validation of payload in SVT-1/1 (June 2002) late and incomplete:-> Some features may be detected as late as 2 months prior to launch !! • Inputs for commissioning plan late and incomplete, mainly in the area of pointing and interference: -> If not available by mid July not part of CVP baseline.-> Delta commissioning required in 2005 or later. • DDS interface lacks performance / robustness-> Initial restrictions on DDS may apply. • OBCP development/validation late:-> Payload OBCPs likely not ready for inclusion in LEOP/CVP baseline. • Payload On-Board Monitoring significantly de-scoped to match existing inputs and DMS capabilities.
