2002 Thurlow Award

Presented to: Mr. Robert J. Erlandson

Citation: For his multiple contributions to the field of GNSS and for his insightful work toward preserving and promoting the spectrum protection for GPS/GNSS and other critical aviation navigation systems.


Mr. Robert J. Erlandson, who recently retired from 28 years at Rockwell Collins, is currently a private engineering consultant in radionavigation and communication systems. Mr. Erlandson has extensive experience in GPS and microwave avionics communication and radionavigation hardware design and system analysis. In addition, he has experience on various domestic and international radio frequency regulatory advisory committees. In 1993, he represented Rockwell on the FCC Mobile Satellite Service Above 1 GHz Negotiated Rulemaking Committee to recommend MSS out-of-band emission levels in the GPS L1 band. He has been a U.S. delegation member to ITU-R Working Party 8D (MSS, RNSS) and was involved with significant involvement in establishing international interference standards for GPS and the frequency allocation for the GPS L5 signal. Since 1994, he has been an active member of RTCA SC-159 Working Group 6 (GPS Interference) and has served as co-chair since 1998. That group recently updated the asessment (RTCA/DO-235A) of the radio frequency interference relevant to GNSS L1. Mr. Erlandson is currently leading the group in preparing a similar assessment for the GPS L5 frequency band.

Mr. Erlandson holds B.E.E. and M.S.E.E. degrees from the University of Minnesota.
