Space Systems FundamentalsCourse # P245SummaryThis four-day course provides an overview of thefundamentals of concepts and technologies of modernspacecraft systems design. Satellite system andmission design is an essentially interdisciplinary sportthat combines engineering, science, and externalphenomena. We will concentrate on scientific andengineering foundations of spacecraft systems andinteractions among various subsystems. Examplesshow how to quantitatively estimate various missionelements (such as velocity increments) and conditions(equilibrium temperature) and how to size majorspacecraft subsystems (propellant, antennas,transmitters, solar arrays, batteries). Real examplesare used to permit an understanding of the systemsselection and trade-off issues in the design process.The fundamentals of subsystem technologies providean indispensable basis for system engineering. Thebasic nomenclature, vocabulary, and concepts willmake it possible to converse with understanding withsubsystem specialists.The course is designed for engineers and managerswho are involved in planning, designing, building,launching, and operating space systems andspacecraft subsystems and components. Theextensive set of course notes provide a concisereference for understanding, designing, and operatingmodern spacecraft. The course will appeal toengineers and managers of diverse background andvarying levels of experience.InstructorDr. Mike Gruntman is Professor of Astronautics atthe University of Southern California.He is a specialist in astronautics, spacetechnology, sensors, and spacephysics. Gruntman participates inseveral theoretical and experimentalprograms in space science and spacetechnology, including space missions.He authored and co-authored more 200 publications invarious areas of astronautics, space physics, andinstrumentation.What You Will Learn• Common space mission and spacecraft busconfigurations, requirements, and constraints.• Common orbits.• Fundamentals of spacecraft subsystems and theirinteractions.• How to calculate velocity increments for typicalorbital maneuvers.• How to calculate required amount of propellant.• How to design communications link.• How to size solar arrays and batteries.• How to determine spacecraft temperature.January 19-22, 2015Albuquerque, New Mexico$1990 (9:00am - 4:30pm)"Register 3 or More & Receive $100 00 eachOff The Course Tuition."Course Outline1.

Space Systems & Space SubsystemsCourse # P152SummaryThis 4-day course in space systems and spacesubsystems engineering is for technical andmanagement personnel who wish to gain anunderstanding of the important technical concepts inthe development of space instrumentation,subsystems, and systems. The goal is to assiststudents to achieve their professional potential byendowing them with an understanding of the basics ofsubsystems and the supporting disciplines important todeveloping space instrumentation, space subsystems,and space systems. It designed for participants whoexpect to plan, design, build, integrate, test, launch,operate or manage subsystems, space systems,launch vehicles, spacecraft, payloads, or groundsystems. The objective is to expose each participant tothe fundamentals of each subsystem and their interrelations,to not necessarily make each student asystems engineer, but to give aerospace engineersand managers a technically based space systemsperspective. The fundamental concepts are introducedand illustrated by state-of-the-art examples. Thiscourse differs from the typical space systems course inthat the technical aspects of each important subsystemare addressed. The textbook “Fundamentals of SpaceSystems” published by Oxford University Press will beprovided to all attendees.InstructorDr. Vincent L. Pisacane is a Fellow of the AIAA, has beenan Assistant Director for Research andExploratory Development and Head of theSpace Department at the Johns HopkinsUniversity <strong>Applied</strong> Physics Laboratory(JHU/APL), the inaugural Robert A. HeinleinProfessor of Aerospace Engineering at theUnited States Navy Academy, and a lecturer inthe graduate engineering program at JohnsHopkins University. He has taughtundergraduate and graduate classes in attitude determinationand control, classical mechanics, guidance and control,launch systems, space communications, space environment,space physiology, space power systems, space propulsion,and space systems engineering. Dr Pisacane is the editor andcontributing author of the textbook Fundamentals of SpaceSystems published by Oxford Press (2005), author of thetextbook The Space Environment and Its Effects on SpaceSystems published by the AIAA (2008), and contributingauthor to The International Space Handbook, in publication.He has been the principal investigator on NASA researchgrants, has served on national and international panels andcommittees, has over 100 publications, and has over 40 yearsexperience in space research and the development ofspacecraft instrumentation, subsystems, and systems. DrPisacane received his PhD in applied mechanics and physicsand a master’s degree in applied mechanics and mathematicsfrom Michigan State, received a bachelor degree inmechanical engineering from Drexel University, and hasundertaken graduate studies in aerospace engineering, aspart of his PhD program at Princeton and had post-doctoralappointment in electrical engineering at Johns Hopkins.Who Should AttendScientists, engineers, and managers involved in themanagement, planning, design, fabrication, integration, test,or operation of space instruments, space subsystems, andspacecraft. The course will provide an understanding of thespace subsystems and disciplines necessary to develop aspace instrument and spacecraft and the systemsengineering approach to integrate these into a successfulmission.February 9-12, 2015Columbia, Maryland$2045 (9:00am - 4:30pm)"Register 3 or More & Receive $100 00 eachOff The Course Tuition."Course Outline1.
