PROFESSIONAL EXPERIENCE
ICO Global Communications, later DBSD, El Segundo, California 1996 – 2012
Director, System Engineering: Member of the ICO/DBSD engineering team procuring and operating the G1 satellite. Performing system performance analysis and problem resolution oriented tasks. Acted as the main ICO liaison for the GBBF development and supported the ICO MIM system development. Analyzed various beam configurations, including a number of different synthetic CONUS beam designs, in terms of their power efficiency and channel power distribution. Prepared link budgets related to various aspects of system operation, including user signals, calibration signals and noise retransmission.
Senior Engineer, Digital Systems: Member of the resident project team for the ICO MEO system at Hughes Space & Communications - later Boeing Satellite Systems.
· Monitored the development and manufacture of the ICO satellites at various levels of development, from satellite to single unit and part level, participating in design, schedule, test data and failure reviews, interfacing with the satellite manufacturer on a daily basis.
· Provided support to the network systems team in London on air interface design, channel coding and modulation, link budgets and analysis of higher performance 2nd generation systems.
· Contributed to the evaluation of the effects of external interference on system performance, and devised strategies and techniques for mitigation of those effects.
ICO Global Communications, London, England 1995 – 1996
Senior Engineer
· Contributed to the development of a novel high penetration subscriber alerting system.
· Participated in the finalization of satellite contract negotiations and early satellite design reviews.
Inmarsat, London, England 1993 – 1995
Senior Ground Segment Engineer in Project 21, the precursor to ICO
· Contributed to system design and air interface development, including aspects of propagation modeling, link budgets, user position determination, frequency assignment, signaling, multiple access, modulation and channel coding, and participated in negotiations with user terminal manufacturers.
ESA/ESTEC, Noordwijk, The Netherlands 1979 – 1993
Communication Systems Engineer in the RF Systems Division
· Provided technical support to various satellite communication projects, with analysis, simulation, contract monitoring, and participation in design reviews.
· Participated as a member of ESA working groups in the definition of TT&C RF modulation and telemetry channel coding standards.
· Set up and supervised laboratory test campaigns related to the development and evaluation of mobile satellite transmission techniques, including the procurement of a customized fading simulator.
· Devised and analyzed a novel rapid CDMA receiver synchronization strategy and algorithm, using digital matched filters, applied to the Prodat mobile satellite data transmission system, as well as VSAT networks and the ESA Data Relay System (DRS).
· Devised and developed novel mobile communication satellite payload architectures based on onboard digital beam forming, using advanced signal processing techniques and technology, including digital ASIC and surface acoustic wave (SAW) devices.
· Performed technical monitoring of R&D contracts on onboard SAW hardware, ASICs, narrowband and spread spectrum modems, codecs, link simulation software, data relay satellite terminals, etc.
· Ran a laboratory test facility dedicated to modeling of the ECS transmission link performance, including 120 Mbit/s QPSK data and analog TV signals conforming to the European PAL and SECAM standards.
