1. From the Installation and Certification Group to the Engineering and Development Section Patrick Grenard Chief, Engineering & Development, IMS Vienna International Centre P.O. Box 1200 A-1400 Vienna AUSTRIA Patrick.Grenard@ctbto.org Presented at: Infrasound Technology Workshop, Bermuda November 2008

2. Outline History IMS/ED mandate Engineering Support functions Technology Development Mastering performances

3. History 1997-2006: – 4 IMS technology sections in charge of installation, certification, operations and support of IMS stations + IDC division 2006: – PTS restructured – 1 Operations Division: Network and Data Systems Operation, Monitoring and Data Analysis, Services Quality &Training, Software Applications – 1 Engineering and Support Division: Monitoring Facilities Support, Network and Systems Support, Installation and Certification Group (ICG) 2008 – ICG transformed into Engineering and Development (ED)

4. IMS/ED Mandate Provide engineering, scientific and project management expertise to: Support IMS network establishment Support IMS network operations and maintenance Support an integrated technology development program to enhance technical capabilities and ensure IMS consistent with scientific and technical state of the art

6. Systems Engineering Process Translate operational users’ needs into requirements and requirements into designs which meet performance, cost, and schedule requirements: ₋Analyze ₋Establish and manage requirements ₋Identify and assess alternatives ₋Design solution ₋Verify and validate requirements and solution performance ₋Maintain the integrity of the system ₋Use an articulated and documented process

7. Conception/ Design Development/ Installation OperationDisposal Obsolescence Management Recapitalize Life Extension Apply Systems Engineering Throughout the Life Cycle Equipment and System Life Cycle Support Upgrade Configuration Management

8. Strategic Directions Prepare for entry into force (completion of the IMS network, calibration, temporary measures, and support to existing system) Maintain and improve performance in a cost effective manner while ensuring coherence and integrity across the IMS (dependability, detection, localisation characterization capabilities) Master IMS performances through modelling and return on experience and development of knowledge integration and systems engineering expertise

9. Prepare for EIF Complete the IMS installation +24 IMS stations not planned 58 stations to Install and 98 stations to Certify

10. Prepare for EIF Sustainment Process IDC SOH Monitoring Tracking OPERATIONS ENGINEERING International Monitoring System Performance Analyzis Technical Expertise Technology Development Systems Design GCI OPERATION CENTER REMOTE FACILITY OPERATIONS SUPPORT NETWORK & SYSTEM OPERATIONS SUPPORT coordination and knowledge transfer

11. Maintain and Improve Performance – Analyze actual performance of the system and identify shortfalls – Provide engineering support solutions to solve existing design issues in the IMS – Provide validated sources of supply for IMS components – Manage a Technical Risk Reduction Program – Develop, maintain and transfer technical expertise as part of a knowledge management program – Enhance, progressively, technical capabilities to ensure that the IMS station related software and associated parameters are consistent with the scientific and technical state of art Close links between measurement systems optimization and analysis techniques  Need for a System Wide and Integrated Approach  Strong relationship IMS/ED - IDC/SA

12. Technology Development Program Technology Watch Technology Watch – A process with elements of Active Obsolescence Surveillance and System Capability Improvement How do we “watch” Technology? Continuous assessment of: > available technologies > level of maturity toward satisfying capability requirements Capability driven approach: > identify functions to be fulfilled > performance expected and required > assess relevance of technology developments > prioritize actions

13.  Identify needs, topics of relevance  Identify shortfalls and areas for improvement  Share with scientific community Technological Development Process  Foster exchanges with the scientific community and promote innovation  Identify actions to address shorfalls  Identify State of the Art,  Identify seeds of high potential impacts Technological development pulled by supply (scientific knowledge, technological advances) and by demand (CTBT needs: providing a response to performance and cost effectiveness challenges)

14. Technology Development Examples 1.Digitizers Approach to the market with up-rated, integrated requirements yielded IMS Digitizer (two competing designs) 2.Station Processors, Communications Interfaces Integrated software/hardware developments in partnership with innovative companies yielded SSI (Standard Station Interface). Open System strategy deployed at 60+ IMS sites 3. SOH Monitoring Software Development 4. Portable Infrasound Array 5. Test sites

15. Toward Mastering Performance Data Acquisition, Modeling, Knowledge integration Operational feedback theoretical studies Technical Expertise Traceability Knowledge integration Reference Data Base of events, engineering issues, models and methodologies

16. Conclusion Engineering and Development in a Transition phase Technology development program initiated Current development focused on solving immediate problems Prioritization of Development Projects Portfolio needed Collaboration with R&T community is essential

18. Modeling Needs Objective: Models to master the acoustical impact of the environment on systems design and performance Models adapted to environment and to its variability in space and time, at different scales (local, regional…) to the infrasound systems (stations and processing ) and to the infrasound functions (detection, localization and characterization) Physical phenomena models (acoustic propagation models) Performance and equipment models (e.g. detection capability of an Infrasound station) Environment models to ensure a ‘state of the art’ acoustic modeling While keeping consistency between environmental knowledge requirements and acoustic modeling
