Abstract:

Digital communications methods are becoming quite popular for situations where the communications channel is marginal for standard voice or data methods. Two challenging examples are communicating using signal reflection from ionized meteor trails in the atmosphere, and low power communications using the surface of the moon as a reflector.  This seminar will provide an introduction to the mechanics of digital meteor scatter communications and the low power earth-moon-earth (EME) communications channel, using amateur radio equipment, a standard personal computer, and free digital software.

Speaker information:

Dr. Hansen works in the area of mathematical and computer modeling of complex systems. He is currently a technical project leader at the INL. Previously, Glen was a staff member at Los Alamos National Laboratory, where he served as the Deputy Group Leader of the Computational Science Methods Group and as the Principal Investigator of the Accelerated Strategic Computing Initiative’s Problem Setup Project. Prior to joining Los Alamos in 1996, he was a member of the computational fluid dynamics group at the Idaho National Engineering Laboratory. Glen is a Certified Software Development Professional, a senior member of the Institute of Electrical and Electronics Engineers (IEEE), a member of the IEEE Computer Society, a member of the Society for Industrial and Applied Mathematics, and a member of the Idaho Section of the American Nuclear Society. He is an active amateur radio operator, KD5HIO, and is the author of two digital radio communications programs. His work has appeared in several seminars and conference presentations, journal articles, and in a monograph on mesh generation.
