2000 Fellow

Presented to: Mr. Mortimer Rogoff

Citation: For his pioneering work in the development of Electronic Chart Navigation Systems and as the principal inventor of Spread Spectrum as used in GPS.


Mr. Mortimer Rogoff is an engineer, author and businessman, whose career spans communications, data processing, and radio navigation. He has been a manager, company officer, inventor and author. He founded and led companies in the data processing and marine navigation fields. He was among the earliest to patent, program, build, demonstrate and sell Electronic Chart Systems. His patent combining radar maps with electronic charts has resulted in today´s major improvement in marine navigation. Additionally, his pioneering invention of Spread Spectrum transmission is now the core of the Global Positioning System, and CDMA cellular telephony. Mr. Rogoff is also known for work on long range radio navigation systems that minimize the effects of atmospheric noise on system accuracy. He was an early proponent of radio navigation systems, and in his volume, Calculator Navigation, demonstrated practical methods of attaining precision ship location. Mort received his B.S.E.E. from Rensselaer Polytechnic Institute and his M.S.E.E. from Columbia University. He is the current President of The Navigational Electronics Charts System Association. He is a IEEE Fellow and a member of the Cosmos Club.
