CHARLES R. TRIMBLE is one of the founders and was president and CEO of Trimble Navigation, guiding it to its dominant role in the Global Positioning System information technology market. Before founding Trimble, Mr. Trimble was manager of integrated circuit research and development at Hewlett-Packard's Santa Clara Division. During his tenure at HP, he was recognized for developing commercial advances in efficient signal processing, high-speed analog-to-digital converters, and digital time measurement techniques to the picosecond level. Mr. Trimble received his B.S. degree in engineering physics, with honors, in 1963, and his M.S. degree in electrical engineering, in 1964, from the California Institute of Technology. He was a member of the Vice President's Space Advisory Board's task group on the future of U.S. space industrial base as a representative of the National Space Council. In September 1994, Mr. Trimble was honored with the Piper General Aviation award from the AIAA for pioneering the manufacture and application of affordable GPS. He recently served on the NRC Committee on Government-Industry Partnerships for the Development of New Technologies and currently serves on the NRC Committee on Capitalizing on Science, Technology, and Innovation: An Assessment of the Small Business Innovation Research Program. Mr. Trimble is a member of the NAE, the Council on Foreign Robotics, and the California Institute of Technology board of trustees.
CHARLES D. WALKER was the first noncareer, industry-sponsored astronaut, serving as payload specialist on three space shuttle missions. On these flights, Mr. Walker operated equipment designed by McDonnell Douglas Astronautics Company for its electrophoresis biotechnology commercialization program (EOS) device. As chief test engineer of the EOS program, Mr. Walker was extensively involved with the laboratory development and spaceflight test of the EOS device. He currently serves in government relations and was previously the senior specialist for Advanced Space Programs Development at the Boeing Company (McDonnell Douglas was acquired by Boeing in 1997). His initial assignment was that of test engineer on the aft propulsion subsystem for the space shuttle orbiters. Mr. Walker has been a member of an independent national space policy review project and served on the former National Research Council Space Applications Board. He has also served on several government and university research center panels. Mr. Walker is currently a board director of the Challenger Center for Space Science Education. Mr. Walker received his undergraduate degree in aeronautical and astronautical engineering from Purdue University in 1971. Prior to joining McDonnell Douglas, he was a project engineer with the Naval Sea Systems Command working on computer-controlled manufacturing systems, a design engineer for Bendix Aerospace and, before that, an engineering technician and a firefighter with the U.S. Forest Service.
