NAVSTAR GPS Biography

Steve F. Russell, Ph.D., P.E.

Dr. Russell has seven years total experience working on the User Equipment Segment of the NAVSTAR GPS Program. He is completely familiar with the RF signal format, spread-spectrum acquisition, tracking, demodulation, and navigation aspects of the system. He has a working knowledge of the Space and Control Segments of the system. He understands the science and practical engineering needed to make the system effective and has worked extensively with both the User Equipment Specification (User System Segment), SS-US-200, and the System Specification, SS-GPS-300. He has played major rolls in the high-antijam military design (GDM) and two low-cost civil designs of user equipment.

Rockwell Profile: March, 1976 to August, 1980
During this period, Dr. Russell worked full time on the User Equipment program at Rockwell-Collins in Cedar Rapids Iowa. At first, he was a System Analyst responsible for all signal processing analysis and acquisition design. He was the project leader for the Phase-I receiver subsystem acceptance testing and the Red-Team project leader for the special manpack design. His analysis and designs are now being used in the Collins GPS user equipment. During his last 6 months with Rockwell, he was the first project manager for the low-cost civil GPS program. This program is now well established and is producing the generation of equipment that will be used by the civil aviation community.

King Radio Profile: August, 1980 to July 1984
Dr. Russell joined King Radio Corp. in Olathe, Kansas as a Principal Engineer and Lab Leader with responsibility for advanced system design, analysis, and implementation. He did the start-up planning, management, and system design for their low-cost NAVSTAR GPS program. He also developed the software configuration management program that specified the design, development, testing, and DO-178 certification of avionics software. He planned, developed, and implemented a completely automated TCXO design and manufacturing capability that produced state-of-the-art units.
