Large Antennas of the Deep Space Network - Dr. Bill Imbriale Colloquium

The Deep-Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in aeronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep-space navigation and communications by disseminating state-of-the-art knowledge in key technologies. It provides an important historical look at the space program's evolving telecommunications systems.
Dr. Imbriale has recently completed one of the books in the series. Large Antennas of the Deep-Space Network traces the development of the antennas of NASA's Deep-Space Network (DSN) from the network's inception in 1958 to the present. It details the evolution of the large parabolic dish antennas, from the initial 26-m operation at L-band (960 MHz) through the current Ka-band (32-GHz) operation on the 70-m antenna used to support radar astronomy observations in the exploration of the solar system and the universe.
Using material from the book, his talk will provide insight into the Antennas of the DSN. He will also speculate on the future developments in the DSN that could be closely allied to the high frequency SKA.

WILLIAM A. IMBRIALE is Senior Research Scientist at the California Institute of Technology's Jet Propulsion Laboratory currently on Sabbatical at CSIRO working jointly with CTIP and ATNF on the SKA.
