Bryan W. Welch is a member of the Communication System Integration Branch of the Communications Technology Division at the National Aeronautics and Space Administration's Glenn Research Center at Lewis Field in Cleveland, Ohio. He is currently part of the Systems Planning Working Group (SPWG) – Position Navigation & Time (PNT) sub-team analyzing benefits of the utilization of laser ranging measurements for orbit determination of Global Positioning System (GPS) satellites and lunar retro-reflectors from ILRS ground stations. He is also performing analysis on the benefits of the utilization of pseudolites on the lunar surface for state determination for cis-lunar, low lunar orbit, high lunar orbit, surface stationary, and surface roving mission phases. Mr. Welch is also a member of the Lunar Architecture Team Navigation sub-team in which he is analyzing the performance of various equipment options for lunar surface roving. Finally, Mr. Welch is involved with the Advanced Antenna Technology task under the Space Communication and Navigation (SCaN) project in which he is investigating the effect of surface errors on inflatable aperture antennas, for which his Master’s Thesis was based on.

Mr. Welch earned his Bachelor’s of Science Degree in Electrical Engineering from Cleveland State University, graduating summa cum laude in May 2003. He earned his Master’s Degree in Electrical Engineering, also at Cleveland State University. He has coauthored many papers, including some presented at the 4th ICNS Conference in April 2004, the ION National Technical Meeting in January 2006, the Ka Band Conference in September 2006, and the ION 63rd Annual Meeting in April 2007. He is a member of Tau Beta Pi and Eta Kappa Nu.
