Susan Irwin, President of the U.S. Of-ice of Euroconsult, is the new AAS Vice President-International. Previously she served on the Board of Directors and Executive Committee. Irwin has spent her career in the space business, particularly commercial communications satellites, and was honored by induction into the Society of Satellite Professionals Hall of Fame in March 2013. She was interviewed on March 11, 2013 by Marcia Smith, Editor of SpacePolicyOnline.com and AAS Board member, about her 30-year career in the space business, the history and future of communications satellites, and her plans as AAS VP-International.
Congratulations on your election into the Society of Satellite Professionals In-ternational (SSPI) Hall of Fame. When was SSPI created?Thankyou! Iwasamongagroupofcol-leagueswhodecidedintheearly1980sthat

How did you get started in the commu-nications satellite business?Igotinvolvedinthelate1970swhenthefirst commercial satellites were beinglaunched.The cable television industrywasgettingstartedwhencommunity-accesstelevision (CATV) stations were able toreceivenationallydistributedprogrammingbyutilizingthenewlylaunchedcommercialsatellites.IwashiredasaconsultanttotheAppala-chianEducationSatelliteProject,whichwasdemonstrating the use ofNASA’sATS-6satellitefordistancelearning,training,andpublicserviceapplications inruralAppa-lachia.TheprojectultimatelyevolvedintoTheLearningChannel.Later I worked for NTIA [the NationalTelecommunications and InformationAdministrationintheDepartmentofCom-merce] as the program manager for itsSatelliteApplicationsProgram,whichwasestablishedtousecommercialsatellitesfor
thesametypesofpublicserviceprogramsthathadbeendemonstratedwiththeATS-6.Wealsodeveloped trainingprograms foremerging countries like India, Indonesia,and the Philippines to demonstrate howsatellitescouldbeusedforeducationandpublicservices.Itwasanexcitingandinter-estingtime.Commercialcommunicationssatelliteswere just being launched – theindustrywas getting started.TheUnitedStateswastheirstcountrytocommercial-ize this business. Itwas a new industry.Everythingwashappening.
What happened to the public service ele-ment of communications satellites as the decades passed?Iwent fromNTIA to a start up thatwasdeveloping private satellite networks forcorporate training –BusinessTelevisionnetworks. We used Ku-band satellites,whichenabledthedistributionofsatellitesignalstorelativelysmallantennasinstalledinurbanareas.ThatwasthebeginningoftheVSAT[VerySmallApertureTerminal]industry.Ourcustomerswerelargecorpora-tionsandgovernmentagencies.Universitiesandnonproitorganizationswerealsousingsatellitesfordistancelearning.ButeventuallydistancelearningmovedtotheInternet.Transmissionwaslessexpen-sive,andtrainingcouldbeaccessedbyin-dividualsondemand.Distancelearningviasatellitewasbroadcastliveinaclassroomwithquestionsoverthephone.Theuseofsatellitesforlivetrainingdiminished.Nowitisalmostallonline.
What are the primary uses of communi-cations satellites now?Television transmission is the largest ap-plication today. Initially satellites wereused as the distribution system for themajorTVnetworkstotheirlocalstations.TVdistributionviasatellitegrewascableTVexpanded.Then,asvideodistributionwentfromanalogtodigital,itbecameeven

morecosteffectivetodeliverviasatellite,whichenabledthewholemultichannelen-vironmenttodaywheretherearehundredsofTVchannels,aswellasdirect-to-homebroadcasting, suchasDirecTVandDish.ThatbusinesswasalldrivenbydigitalTV.Satellites are perfect for delivering anysignalpoint-to-multipointover largegeo-graphicareas,includinginternationally.Itdoesn’tcostanymoretosendasignal toathousandlocationsasitdoestoone.TVdistribution is probably 60-70percent ofsatellitecommunicationsrevenueglobally.Theremaining30-40percentof thebusi-nessisdatainvariousforms–forVSATs,cellularbackhauls,businesscontinuity,andbroadbandaccess.Satellitebroadbandisagrowingapplication in ruralareasandanincreasingly cost-effective alternative tootherformsofbroadband.“HighThrough-putSatellites”arebecomingcompetitivetoterrestrialsystems.
Was there a big change in the satellite business with the privatization of Inmar-sat and Intelsat?Yes,therewasabigdifference.Privatizationandderegulationmade satellite operatorsmore competitive, aswell as leaner andmoreproitable.
Was there a cost in terms of innovation? Did companies decide not to invest their proits in innovation?Youcan’thaveatech-basedindustrywith-outinnovationandwithoutdevelopingnewapplications and new products and newsolutions.Otherwiseindustrydoesn’tmoveforward.Withnewapplicationscomenewproitcentersandrevenuestreams.
In terms of the overall cost-beneit for sat-ellite operators, how much difference do launch costs make? If launch costs were to be cut that in half, for example, since companies are getting 15-20 year satellite lifetimes, is the launch cost important?Costs are typically expressed as the costofbuilding,launching,andoperating,notreallyasthecostoflaunchingcomparedto15yearsofoperationalrevenue.Ifitcosts$300milliontobuildandlaunchasatellite,andlaunchismaybe$100millionofthat,I can’t really say how that compares to
revenuesforthelifeofsatellites.
A big topic of conversation today is hosted payloads. Do commercial satel-lites have a lot of unused capacity so they can accommodate other users on their satellites?No,that’snotwhatit’sabout.Hostedpay-loadsarenot reallyanewconcept.Whatis new is the push to host governmentpayloads on commercial satellites.Theideaisforthegovernmenttomeetmissionrequirementswithoutbuildingandlaunch-ingitsownsatellites.The satellite operator beneits by sharingtheriskandcostofbuildingandlaunchingthesatellitefromthebeginninginsteadofwaiting for the government to decide toleasecapacityafterit’sinorbit.Thegov-ernmentbeneitsbecauseitownsapieceofthesatelliteandisdevelopingthatpayloadasthesatelliteisbeingmanufactured.Thegovernmentcanmeetitsrequirements,andthe satellite operator reduces its cost andsharestherisk.It’sawin-winsituation.
What are the big issues facing the com-mercial satellite industry today? Will there be any big ights at the next World Radio Conference (WRC) in 2015?Oneofthebigightsisbetweenthewirelessindustry ighting forC-band frequenciesandthesatelliteindustrythathasbeenus-ingC-bandfrequenciesforyears.AlthoughthesatelliteindustryhasmovedtoKu-bandinmanyplacesintheworld,C-bandisstillimportantinsomeareas,particularlywhererainattenuationisaproblem.There’sverylittleKu-band left, too,which isonerea-son thatKa-band satellites are becomingmorepopular.But there ismuchmoreofitavailableandlittleinterference,soHighThroughputSatellitesusingspotbeamsforfrequencyre-usearebeingbuiltbymostofthemajoroperatorsworldwide.Interference issues can be significant,whetheraccidentalordeliberate(jammingsignalsthatarepoliticallymotivated).Theotherissueforthebusinessasawholeis that satellites are not cost competitivewithiber for point-to-point communica-tions.ThatmaychangesomewhatasHighThroughput Satellites get launched, but,overall,theproliferationofiber,wireless,

Rearming for the Cold War, 1945–1960by Elliott V. Converse III. Washington,D.C.: Historical Ofice, Ofice of theSecretary of Defense, 2012. 780 pages.ISBN 9780160911323. $86.00 US(hardback, illustrations, tables, charts,notes,appendices,glossary,bibliography,index).
A glance at the title of this volume,the irst of ive in a new series on thehistory of acquisition of major newweaponsystemsbytheU.S.Departmentof Defense, might lead one to wonderwhy itmerits a review in Space Times.It should not take long, however, forhistorically informed readers to recallthat the military services studied thefeasibility of earth-circling spaceshipsin the immediate postwar period, andnearly all development of U.S. spacelaunch vehicles during the 1950s–early1960s occurred under army, air force,or navy direction. Furthermore, themilitary services expended substantialresources during the early years of thecold war on research and development(R&D)ofsatellitesystems_bothorbitaland terrestrial elements_initially, forpurposesofintelligence,reconnaissance,surveillance, communications, andnavigation, with other space-basedapplications following after 1960.

evolution of acquisition processes andpractices during 1945–1960 from theperspectiveoftheOficeoftheSecretaryof Defense and from each individualservice. Beginning with his prefatoryexplanationofhowtheterm“acquisition”evolved and his irst chapter on WorldWarIIasa“watershed”foracquisition,and ending with an elaboration of theascendancy of the weapon systemconceptwithineachoftheservicesafter1953,Converseexposesmisconceptions,misinterpretations, and factual errorsfoundinsecondarysources.Hecarefullyand methodically blends the content ofprimary documents and the insights ofhis scholarly predecessors to weave anintricatenarrativebasedoncasestudies.
Some astronautics professionalsmightindtheselectionofspeciiccaseslackingwithrespecttospacesystems.Amore careful reading, however, revealsthat R&D and production of guidedmissiles_the source of most earlyU.S. space launch vehicles_becamekey drivers in the transformation ofmilitary acquisition processes. Herein,thisreviewerindsonereasonRearming for the Cold War might prove usefulto nonmilitary readers. Knowing howand why military acquisition changedat the dawn of the space age mightgive NASA oficials, corporate leaders,congressional staff members, and
elected representatives insight as theywrestle to make tough decisions in aseverelyconstrainediscalenvironment.A refreshing exception to the manybureaucratic histories devoid of humanactors,Converse’svolumebringstolifethe roleof individuals inchanginghowthe U.S. military acquired its hardwareduringlushandnot-so-lushtimes.Morethan a half-century later, we can learnfromthis.
By understanding proceduralproblems, organizational impediments,and political roadblocks that plaguedacquirers of military systems in thepast, acquirers of space systems todaymightindthemselvesbetterpreparedtonavigate troubled waters. Recognizing,as Converse does, that goals andoutcomeswerenot the same thing, thatissures between R&D and production/procurementcausedscheduledelaysandcostincreases,thatlackofclearlinesofresponsibilityoraccountabilityhamperedproduction, that adoption of systemsengineering practices and concurrencyinieldingnewsystemshadadownside,and that technical achievementssometimes masked serious deicienciesinacquisitionorganizationandprocessesmight help today’s acquirers chart lesshazardous courses. Knowing thesethings also might humble acquisitionexperts, who should realize that for allthesigniicantadjustmentstoacquisitionapproachesovertime,hauntinglysimilarchallengespersist.
