State-of-the Art Satellite Communications – Technologies and Solutions course

Share |


Technical Training Short On Site Course Quote

Modern satellite communications networks and systems rely on innovations in both the radio frequency (RF) and baseband domains. Introduction and application of these cutting-edge technologies and processes are addressed by this in-depth three day course. Established during the last decade, technologies that make a difference include high throughput satellites, high power solid state amplifiers (up to one kW), array antennas for mobile platforms, channel linearization, turbo codes, DVB-S2 extensions and adaptive coding and modulation (ACM). The path forward involves the right choices in terms of which technologies and their introduction – and the use of integrating tools such as system simulation and optimization. Investments in new satellites, earth stations and network management systems need the right system-level view, and at the same time, demand a thorough understanding of the underlying details within the RF aspects (propagation, link availability and throughput) as well as the ability of baseband systems to provide throughput under expected conditions and to end users. The course examines real options and makes use of quantitative analysis methods and systems analysis to evaluate the technology horizon.



Bruce R. Elbert, MS (EE), MBA, Adjunct Professor (ret), College of Engineering, University of Wisconsin, Madison. Mr. Elbert is a recognized satellite communications expert and has been involved in the satellite and telecommunications industries for over 40 years. He founded Application Technology Strategy, LLC, to assist major private and public sector organizations that develop and operate cutting-edge networks using satellite and other wireless technologies During 25 years with Hughes Electronics, he directed the design of several major satellite projects, including Palapa A, Indonesia’s original satellite system; the Galaxy follow-on; and the development of the first GEO mobile satellite system capable of serving handheld user terminals. Mr. Elbert was also ground segment manager for the Hughes system, which included eight teleports and 3 VSAT hubs. He served in the US Army Signal Corps as a radio communications officer and instructor. By considering the technical, business, and operational aspects of satellite systems, Mr. Elbert has contributed to the operational and economic success of leading organizations in the field. He has written nine books on telecommunications and IT.
