SUMMARY
For the last 25 years I have primarily worked in the satellite telecommunications industry. I have worked as a development engineer for two satellite ground control segment (GCS) manufacturers (HNS USA and NERA Norway) as well as spending 16 years at Inmarsat, which operates a constellation of 10 satellites providing voice & data communications on a global scale. At Inmarsat I started as a system engineer, but more importantly have managed two major GCS procurement, development and installation projects from start to finish. This involved the following high level duties forming and leading a team of skilled Inmarsat RF, hardware, software and systems engineers:
1. The creation of a Statement of Work (SOW) defining project management, technical and operational requirements for the development of the GCS;
2. Issuance of a Request for Proposal (RFP) to a list of suitably qualified sub-contractors;
3. Selection of a prime sub-contractor based of the responses to the RFP and SOW;
4. Negotiation with the selected sub-contractor for best price and schedule;
5. During the GCS development day to day decision making with respect to documentation, hardware and software deliverables and testing plans. Also provide assistance to contracts staff for agreement on milestone payments;
6. Definition and procurement of test equipment (network simulators, test terminals, etc.) required for interim, factory and on-site testing;
7. Selection of suitable sites to host and operate the GCS equipment. Negotiate with site service providers;
8. Review and accept the various design, implementation and test phases of the GCS development;
9. For factory acceptance testing (FAT) – review and approve the FAT plans. Provide engineering effort to witness the hardware, software and system testing required. Review the results of the FAT to determine suitability for advancement to on-site installation.
10. Provision of suitable training and documentation for on-site and Inmarsat HQ operational staff;
11. Provide engineering effort to supervise on-site installation leading to an on-air system acceptance test (OSAT);
12. Conduct OSAT leading to final acceptance and the start of the operational and warranty period.
I have also provided the programme management role on an ESA contract where Inmarsat provided the project management and integration expertise. A number of sub-contractors report through Inmarsat to ESA.
Prior to the satcom work I worked on 3 Royal Navy contracts and on CAD/CAM applications as a programmer/analyst.

6/1989-2/1990 ITL, Hemel Hempstead, Herts
Involved in code and testing of an international telemessage gateway, called a Telegram Retransmission Centre (TRC). The system was for BTI and was intended to replace an older system and to provide more functionality and better performance.
The system could accept telex, gentex and telegraph messages and retransmit them in the same form or in another form, including X.25.
The system ran on fault tolerant multi-processor computers (Sequoia) with approximately 200 UNIX processes providing the communications, operator interface and data base functionality.

3/1989-5/1989 Oxford University Press, Walton St., Oxford, Oxon
I designed and coded programs that allowed access to the Shorter Oxford English Dictionary (SOED) entries held on disk. I designed and coded a program that maintained the database's integrity. These programs were run on a SUN 4/280 and were used by lexicographers, who accessed the database via networked PS/50s, using a special lexical editor. The PS/50 interface to the SUNs was via Remote Procedure Calls (RPCs).
I modified the lexical editor on the PS/50 to improve screen handling and reference searching capabilities.

The package was the software part of MISI's value added package, that allowed MISI to become a VAD for IBM. The program was written in 8088/8086 assembler. The program offered some terminal emulations (ADM31, VT100, TV920, etc.) and allowed ASCII and binary transfers by use of the XMODEM protocol.
I designed and coded a Medicare 'B' claims entry and transmission package. The package was for doctor's office use in those states that used the Travelers insurance company as their Medicare carrier. The program was 98% written in 'C' and 2% in 8088/8086 assembler, and ran on IBM PC/XT/AT computers. Program development and support was on Zilog and AT&T UNIX machines.
