Consultant to Boeing on the FCS project.

I worked for Sattel on an extension/upgrade of the Indonesia telecom network overlay that I did for Hughes (see below). The Indonesians were having trouble finding telephone central office products that worked with their legacy Dutch telephone network, and they asked Sattel to design one. A telephone switch is a huge undertaking;

Designed test panels (hardware devices to generate realistic system signals) for environmental testing of storage tube radar display units. (I learned about reading schematics, analog hardware, op amp math, analog test equipment, basic troubleshooting methodology, etc.) Investigated and isolated a problem with new radar tubes. Supervised installation of new test sets at three Air Force bases. (I learned how supposedly simple instructions can be misinterpreted, and also how to dress in cold weather.) As a radar subsystem engineer, I wrote interface specs and assisted unit engineers with interpreting and executing them. (I learned how a clean interface spec and good emulators make system integration a breeze.) For a scientific spacecraft with multiple instrument packages from international organizations: I designed a scripting language and implemented an interpreter for testing and integrating the packages, and assisted the international engineers in writing test scripts. The interpreter was written in Sigma 5 assembly language and ran on a real-time mainframe which also received and analyzed spacecraft telemetry. (My first experience with real-time.) Programmed a portable radar test set and provided on-site assistance in France to the prime contractor. I used an 8085 macro assembler to create a test language which was directly usable by the radar hardware engineers. The test set hardware generated RF test signals which fed into the radar antenna. (Good thing I knew about radar! My first embedded system.)
