Expert is an award-winning lecturer, writer, mathematician, and engineer who has conducted successful engineering design studies for the GPS and various communication satellites and booster rockets. He helped mastermind the GPS constellation, performed orbit selection trades and on-orbit maneuvering studies for commercial communication satellites, and optimum trajectory shaping and six-degree-of-freedom trajectory reconstructions for the Saturn 5 moon rocket. He also helped engineer the giant geosynchronous solar power satellites, the Spitzer space telescope now in an Earth-trailing orbit around the sun, the manned Mars mission of 2016, and the chemical inter-orbital shuttle designed to ply a regular trade-route between the Earth and the moon. His important contributions to the space-based GPS radio-navigation system have included force-multiplier effects and survivability studies for the US military, and studies intended to maximize the utility of the GPS receivers used for terrestrial, aviation, and space-borne applications. The expert has written and sold 1.7 million words, including 30 technical books. He has delivered motivational, technical, and scientific lectures in more than two dozen different countries scattered across six continents. He also helped design an exhibit for the Smithsonian Institution, made guest appearances on 25 television shows, applied for a patent, lectured professionally and composed 19,000 words for Encyclopedia Britannica. As an expert witness, he has been recruited to work on cases totaling more than $300 million. His assignments have included summarizing prior art, chart design, researching and writing, providing historical perspectives, evaluating patents, conducting engineering trade studies, polishing and rewriting the contributions of others, developing clear, persuasive and accurate story lines easily understood by aerospace experts, attorneys, judges, and layman alike.

Expert provided advice on navigation satellites and constellation design for Damlier-Benz in Friedrichshafen, Germany.
He wrote proposals and developed small business concepts for Consultare International in Bethesda, Maryland.He designed, wrote, and edited a video presentation announcing that Boeing Aerospace had become responsible for the next generation of GPS satellites.Developed, wrote, and polished effective advertising copy touting a new family of GPS receivers being marketed by Navstar, Ltd., in Daventry, England.Instructed young South African engineers on the fundamental principles of orbital mechanics and reviewed their emerging Greensat satellite design at Stellenbosch University and at Houwteg Corporation near Cape Town, South Africa.

Work History

Years Employer Title Department Responsibilities
Years: 1994 to Present Employer: Undisclosed Title: Expert witness, author, consultant, and professional platform lecturer Department: Responsibilities: About one week each month, the expert gets the opportunity to visit one of the 10 NASA bases, a university campus, or a military installation where he teaches the next generation of young rocket scientists how to conquer space. Those stimulating visits are interspersed with keynote lectures, expert witness work, and consulting assignments.
Years: 1964 to 1994 Employer: Rockwell International Title: Senior Member of Technical Staff Department: Systems Engineering Responsibilities: Expert handled mathematical derivations, computer simulations, and systems analysis studies for the Saturn 5 moon rocket, moon rocket, the manned Skylab, Mars and asteroid missions, and the Navstar Global Positioning System. He determined the best sun synchronous orbit for the Canadian radar satellite and reviewed the problems and the promise of the GPS receiver carried on board the Landsat D. earth resources satellite. He studied and evaluated the space debris hazard for the giant 20-square-mile solar power satellite -- and the best maneuvering sequence to move it from its low-altitude assembly orbit to its final destination orbit at geo-sync. He managed a small proposal for the Personal Communicator, an early device similar to today's Iridium handsets. It was designed to relay telephone messages to and from an orbital antenna farm at geo-sync. It was also designed to handle remote teleconferencing, electronic mail, and television and telephone relay operations. He performed a variety of studies for the GPS, including force-multiplier effects on modern battlefields, survivability studies, and autonomy studies intended to minimize the number of military personnel required to keep the constellation in operation. He conducted numerous studies centering on the utility of the GPS to the Federal Aviation Administration. These included an early proposal for geosynchronous overlay satellites of the type now being planned or operated by the United States, Europe, and Japan, among others.
Years: 1961 to 1964 Employer: McDonnell Douglas Title: Senior engineer Department: Space division Responsibilities: Expert helped code the six-degree-of-freedom preflight and post-flight trajectory simulation programs for the S-4B stage of the Saturn 5 moon rocket. Using advanced mathematics, he worked out various ways to enhance the performance capabilities of the Saturn 5. These included optimal trajectory shaping and optimal fuel biasing to cover for statistical uncertainties in the booster rockets' day-to-day performance variations.
Years: 1959 to 1960 Employer: McDonnell Douglas Title: Aeroballistics engineer Department: Space division Responsibilities: Expert handled orbital mechanics studies for the Transit navigation satellite constellation consisting of six gravity-gradient stabilized satellites positioned in polar "Birdcage" orbits. He also developed a closed-form mathematical derivation used in evaluating the perturbations induced on various low-altitude satellite orbits by the Earth's equatorial bulge. He set up trajectory simulations and range safety evaluations for the two thor boosters used in launching suborbital ballistic capsules in which an early communication satellite, the Echo Balloon, was tested in space. He evaluated the probability of camera recovery and established the identity of two previously unidentified flying objects that unexpectedly entered the camera's field of view.
Years: 1958 to 1958 Employer: Naval Ordinance Laboratory Title: Student Trainee Department: Silver Spring, Maryland Responsibilities: Expert performed kill probability studies for the Tartar and Talos shipboard defensive missiles. He evaluated the effectiveness of the "continuous rod" warheads that expanded in "accordion fashion" into a circle of metal intended to cut attacking airplanes in half.
