December 9-11, 2014Columbia, MarylandMarch 3-5, 2015Columbia, Maryland$1895 (8:30am - 4:30pm)"Register 3 or More & Receive $100 00 eachOff The Course Tuition."Video!Satellite Communications Design & EngineeringA comprehensive, quantitative tutorial designed for satellite professionals Course # P214www.aticourses.com/satellite_communications_systems.htmInstructorNewlyUpdated!SummaryThis three-day (or four-day virtual) course isdesigned for satellite communications engineers,spacecraft engineers, and managers who want toobtain an understanding of the "big picture" of satellitecommunications. Each topic is illustrated by detailedworked numerical examples, using published data foractual satellite communications systems. The course istechnically oriented and includes mathematicalderivations of the fundamental equations. It will enablethe participants to perform their own satellite linkbudget calculations. The course will especially appealto those whose objective is to develop quantitativecomputational skills in addition to obtaining aqualitative familiarity with the basic concepts.Chris DeBoy- leads the RF Engineering Group in theSpace Department at the JohnsHopkins University <strong>Applied</strong> PhysicsLaboratory, and is a member of APL’sPrincipal Professional Staff. He hasover 20 years of experience in satellitecommunications, from systemsengineering (he is the lead RFcommunications engineer for the New HorizonsMission to Pluto) to flight hardware design for both low-Earth orbit and deep-space missions. He holds aBSEE from Virginia Tech, a Master’s degree inElectrical Engineering from Johns Hopkins, andteaches the satellite communications course for theJohns Hopkins UniversityWhat You Will Learn• A comprehensive understanding of satellitecommunication.• An understanding of basic vocabulary.• A quantitative knowledge of basic relationships.• Ability to perform and verify link budget calculations.• Ability to interact meaningfully with colleagues andindependently evaluate system designs.• A background to read the literature.Course Outline1.
