The course provides a provenapproach to the design of modern earth stations, from thesystem level down to the critical elements that determinethe performance and reliability of the facility. We addressthe essential technical properties in the baseband and RF,and delve deeply into the block diagram, budgets andspecification of earth stations and hubs. Also addressedare practical approaches for the procurement andimplementation of the facility, as well as proper practicesfor O&M and testing throughout the useful life. The overallmethodology assures that the earth station meets itsrequirements in a cost effective and manageable manner.InstructorBruce R. Elbert, (MSEE, MBA) is president of anindependent satellite communicationsconsulting firm. He is a recognizedsatellite communications expert andhas been involved in the satellite andtelecommunications industries for over40 years. He founded ATSI to assistmajor private and public sectororganizations that develop and operate digital videoand broadband networks using satellite technologiesand services. During 25 years with HughesElectronics, he directed the design of several majorsatellite projects, including Palapa A, Indonesia’soriginal satellite system; the Galaxy follow-on system(the largest and most successful satellite TV system inthe world); and the development of the first GEOmobile satellite system capable of serving handhelduser terminals. Mr. Elbert was also ground segmentmanager for the Hughes system, which included eightteleports and 3 VSAT hubs. He served in the US ArmySignal Corps as a radio communications officer andinstructor. By considering the technical, business, andoperational aspects of satellite systems, Mr. Elbert hascontributed to the operational and economic successof leading organizations in the field. He has writtenseven books on telecommunications and IT, includingIntroduction to Satellite Communication, Third Edition(Artech House, 2008). The Satellite CommunicationApplications Handbook, Second Edition (ArtechHouse, 2004); The Satellite Communication GroundSegment and Earth Station Handbook (Artech House,2001), the course text.Course # P142Course Outline1.
