2009 Weems Award

Presented to: Edward H. Martin

Citation: For his contributions to the selection of the P code and C/A code GPS waveforms, for his leadership in the development of the first GPS receiver and for his years of contributions to the application of GPS to the U.S. military and Allied users, civil transportation systems including aviation, and his clear and concise teachings to the next generation of space-based navigation developers.


Edward H. Martin recently retired as a Boeing technical fellow with national recognition for his extensive expertise in GPS due to a unique 41 years of technical contributions in the analysis, synthesis, development, and production of military user navigation sensors, and military satellite spread spectrum ranging and communication payloads.

His dual experience in these areas has covered the period from initial defense navigation satellite development program concept formulations through all development phases of GPS user and space segments from Phase I through the GPS III architecture and signal studies leading to future enhancements.

The two core specialties that he mastered were both in the area of modern estimation theory. The initial work was in the application of extended Kalman filtering to real time aided inertial systems, and the other was the analysis of coherent communication performance for satellite links with PRN code or frequency hopping spread spectrum modulations.

Edward focused on applied research in state-space analysis and simulation of Doppler aided inertial navigation for tactical aircraft which culminated with his mechanization for the FB-111/F-111. With a dual state design tool he investigated numerous options for Omega, Loran, and TACAN aiding including a 621-B pseudo-ranging option. The insight gained with the improved ranging PRN codes motivated him to join the Magnavox Research Lab as program manager for the pursuit, capture, and technical direction of the Phase I control/user segment concept development. During this innovative period he was responsible for evaluating and recommending the L1 and L2 signal options based on extensive performance data and conflicting requirements for precision, dynamics, jamming, rapid acquisition and low risk and cost.

In 1978 Mr. Martin returned to Rockwell International for development of the Phase II full scale user equipment into eight mission configurations, and in 1984 managed the GPS Block IIA production satellite upgrade with L3/L4 and cross-link signal additions. He was an identified member of both Rockwell Space and Rockwell Collins division teams for the 1992 Collier Award given to a government/industry team for GPS implementation.
