Professional Experience

Job title : Chairman of inquire board 2015
Company’s name : Thales Alenia Space
Address :  Rome.
Chairman of inquire board team and pre alert investigation team leader for the inquiries activities involving in flight US sensor failure.

Job title: AOCS Expert   2014
Finalized the AOCS technical support for sicral2 program deployed on Space Bus 4000 B3 platform, including a complete review of the whole set of flight operation procedures  on SCOSS system. Developed further sw patches in order to improve the operational capability of military satellites developed on Italian platform (PICS)

 

Job title: AOCS Responsible for competence transfer process   2013
After five years of competence transfer process between Thales France and Thales Italy for the satellite platforms called Space Bus 4000 B2 and B3 I acquired the AOCS engineering design authority certification at all levels. In the frame of Athena Fidus program, certification as lead center has been granted through training on the job, I was the AOCS responsible for the activities from preliminary design to shipment to the launch site phases. All the reviews with the customers: C.N.E.S./A.S.I./D.J.A./Italian M.O.D. have successfully supported, meeting due dates.

 

Job title: AOCS Expert for Italian satellite platforms at MOD’s spacecraft control center   2012 -2011
AOCS responsible for the longitudinal re-location maneuvers of the Sicral 1 satellite. All the activities had been supported by dedicated flight operation procedures that allowed it to successfully perform the maneuvers even if the satellite had accomplished its nominal operational life in 2011 and was affected by multiple single point failures on the avionic equipments.
  
AOCS/OBSW reference for the tests on the ground (including the update of the satellite software simulator models) and in flight uplink and validation campaign of the new functionality in the satellite on board SW allowed  usage of an arbitrary RCT configuration between main and redundant items used for the attitude control.

 

Job title: AOCS responsible and  team coordinator  2010
AOCS responsible and team coordinator for Athena Fidus program, managed as part of the "training on the job" during the engineer competence transfer between Thales Alenia Space France and Italy

 

Job title: AOCS and FDIR specialist   2009-2007
AOCS specialist in the “Project support Team” during the Launch and Early Orbit Phase of satellite SICRAL 1B (Telespazio 4/2009);

AOCS/DHS support during, Satellite integration tests and Thermal Vacuum campaign for SICRAL1B satellite.
Team coordinator and AOCS specialist in the on going Thales internal technological transfer for Space Bus 4000 B2 satellite platform.

AOCS and FDIR technical responsible for the SICRAL 1B sub system integrated test on the avionic test bench.AOCS specialist in the “Project support Team” during the Launch and Early Orbit Phase of satellite Cosmo 1 and 2 (Telespazio 6/2007, 12/2007)

 

Job title: AOCS SW designer responsible  2006
Designer responsible for a new emergency operative mode (Safe Earth Pointing Mode)  for geo satellite. Responsible for the relevant algorithms design and ADA code implementation, sw testing and verification on the Avionic test bench. Project support specialist during the campaign for a new code uplink in the in-flight satellite on board software, tests  and validation campaign. The effectiveness of the performance observed in flight successfully made SEPM the base line for GEO recovery mode of all the subsequent satellite programs.

 

Job title: AOCS attitude control loop designer, and avionic equipment procurement 2005-2004
Designer responsible for PID regulator gains and structural numerical filters fine tuning for the attitude control low implemented in the LEO satellite platform on Cosmo Sky-Med programs. I was involved in the FDIR test campaign at sub system level on the avionics test bench. Technician responsible for the procurement of the following units:  Gyro Ferranti, for Cosmo satellites; Honeywell Momentum wheel and the Ring laser gyro.
AOCS Sw development responsible for the Sicral 1B program. In particular I designed  the sun sensor pre-processing SW algorithm required by the substitution of the Edo-Burns Analog sun Sensors with the Galileo APS smart Sun Sensor

PID regulator gains and structural numerical filters fine tuning for the attitude control low implemented in the LEO satellite platform on the Radarsat program. I was involved in the FDIR test campaign at a sub system level on the avionics test bench.

 

Job title: AOCS specialist 2002- 2001
AOCS specialist in the “Project support Team” during the Launch and Early Orbit Phase of satellite Atlantic Bird-1 (Telespazio 8/2002);
Technical reference for the design, validation and installation of the SW patch in the satellite on board software. Each patch has been coded in the ADA language. The relevant machine code properly conditioned was installed in the satellite static data base patch area. 4 patches were successfully uplinked in the Atlantic Bird -1 firmware.
In the frame of  after sales care, I was involved in the long term  h24 AOCS Project support on site, in spacecraft control centres, in case of possible malfunctions on both Atlantic Bird-1 and Sicral programs;
AOCS technical reference for the PICS platforms Customer care.

PID regulator gains and structural numerical filters fine tuning for the attitude control low implemented in the GEO satellite platform. In  particular  previous parameters were  tuned to 9   operative modes (Sun Acquisition Mode, Earth Acquisition Mode, Gyro Control Mode, Apogee Motor Firing, Normal mode, Station Keeping mode, Tranquilization Mode, Robust Earth Pointing mode, Emergency Sun Acquisition mode) , issuing the relevant design description , performance and stability analysis, pointing budget.
Galileo IRES-NE SW simulator (language Fortran 90) was upgraded in the closed loop sw simulator (DSS acronym of Dynamic Simulator software)
Sub system test on the Avionic Test bench. During this campaign the attitude performance was validated and achieved by each satellite operative mode. Test environment allowed a simulation in the closed loop during the satellite flight in the transfer and geostationary orbits. Satellite Flight units and EQM models were used during this validation. The FDIR test campaign was successfully performed. LEOP operative mode sequence was simulated in order to validate the Flight Operation Procedure used at the Telespazio centre. Test plan and test report documents were issued at the time.
