ATI's Advanced Satellite Communications Systems course
|
|
Summary:
This three-day course covers all the technology of
advanced satellite communications as well as the
principles behind current state-of-the-art satellite
communications equipment. New and promising
technologies will be covered to develop an
understanding of the major approaches. Network topologies,
VSAT and IP networking over satellite.
Instructor:
Dr. John Roach is a leading authority in satellite
communications with 30+ years in the SATCOM
industry. He has working on many development
projects both as employee and
consultant/contractor. His experience has focused
on the systems engineering of state-of-the-art
system developments, military and commercial,
from the worldwide architectural level to detailed
terminal tradeoffs and designs. He has been an
adjunct faculty member at Florida Institute of
Technology where he taught a range of graduate
communications courses. He has also taught
SATCOM short courses all over the US and in
London and Toronto, both publicly and in-house
for both government and commercial
organizations. In addition, he has been an expert
witness in patent, trade secret, and government
contracting cases. Dr. Roach has a Ph.D. in
Electrical Engineering from Georgia Tech.
