10Business Case from Cost Analysis Aerospace Corp modeled US Satellite Market to quantify savings on cost of busModel included capture rate, technology insertion, obsolescence, integration complexity, organizational complexity, etc.Model reviewed twice by ODNI CAIGFindings:Over 17 years and 442 satellitesSavings was $18.8B (29%)Payback Period was 9 YearsCommercial space has the greatest savings due to high volume (learning)Government savings reduced by low volume (learning) and organizational complexityNot all SUMO benefits were monetizedNet present value through ease of reconfigurability should increase
11…a word about the Cost Model Modeled full plug and playIndustry has made clear they are not ready for full plug and play; SUMO cost analysis will differ but this model gives a first approximation of savingsModeled 5 to 7 years satellite bus acquisitionIndustry feedback indicates 2 to 3 years is reasonable…would accelerate crossover pointModeled the costs of two full satellitesNew approach models delta costs on top of funded project…reduces upfront NRENRO not modeled to gain learning from commercial industryCommercial industry buying 20 satellites per yearModeled increased organizational conflict as more participants engaged and provided inputReduced savings by 30%; realistic for the first decade but reasonable to expect conflicts to be resolved over time (based on MilSTD-1553 experience)An Average of 29% Savings on the Cost of a Bus is Significant

21EU Standardized External Power Supply In 2009 several government, consumer and industry initiatives resulted in the European Union's specification of a common External Power Supply (EPS) for use with data-enabled mobile phones sold in the EU.The "external power supply" is the AC power adapter that converts household AC electricity voltages to the much lower DC voltages needed to charge a mobile phone's internal battery.Although compliance is voluntary, a majority of the world's largest mobile phone manufacturers have agreed to make their applicable mobile phones compatible with the EU's common External Power Supply.From

23Space Avionics Open Interface Architecture (SAVOIR)* SAVOIR: an undertaking led by space European Agencies and Industries aiming at promoting Space Avionics based on Open InterfacesIn its first phase, SAVOIR has federated the space avionics community around the concept of reference architectures, standard interfaces, and generic specifications. All these elements are expected to favor the existence of compatible Suppliers product lines. The major outcomes of the initial phase are R&D roadmaps and a prioritized list of building blocks.SAVOIR second phase includes the refinement of reference architectures, the elaboration of a product portfolio, and the production of two sets of generic specifications covering on-board computer (OBC) and data concentrator (RTU) functions. The portfolio includes also many items related to architectures, communication protocols, data handling services, software libraries, sensors, actuators together with underlying enabling technologies. Each item could lead to a generic specification, validation through prototyping and eventually product(s) with an attached availability date for a given Technology Readiness Level [TRL].The maturity and completeness of the SAVOIR concept will be assessed by building lab demonstrators integrating a consistent set of items. The selection criteria for those items will be driven by their maturity at a given date with the particular goal of demonstrating their readiness for project use.*From ESA Website (http://www.congrex.nl/11c22/)
24Tenets for Success Leverage Existing Standards and Think Global Use existing standards to the extent practical (based upon industry consensus).Examples: Space Modular and P&P standards are being developed by AFRL, ESA, NASA and industry. Also Consultative Committee for Space Data Systems (CCSDS) standards body has made significant progress on Electronic Data Sheets (EDSs).Short-term: Start with US Stakeholders; Long-term: Establish international standards Space Industry ConsensusIndustry consensus for universalized component interface standards and common qualification environment standards through existing standards bodiesInclude participation from U.S. space agencies, commercial satellite operators, spacecraft primes, and component manufacturers.Avoid Commoditization – Protect Intellectual PropertyFocus on data bus interface with sub-systems & components. Avoid defining “inside the box” where unique designs and intellectual property reside.Allow vendors to differentiate capabilities while maintaining standard interfaces.Avoid innovation “lock out” – a common problem for standards that over reach.Natural Break-In Points for Gradual IntroductionOpportunistic insertion of SUMO into “natural break in points” – where primes or component manufacturers are developing new products.Introduce SUMO early during the concept/design phase – avoids disruption of existing solutions, architectures, sunk costs and vested equities.
25Potential Advantages Beyond Cost Savings BenefitSatellite Investor or UserUS Space Industrial Base (SIB)National Security Space StakeholdersMission AssuranceAs P&P bus and CCs become heritage -- they will enhance reliability and overall mission assurance.Lower risk profiles decrease cost of insurance and improves global competitiveness.NS often seeks high levels of mission assurance via heritage P&P and CCs.Increased Cost SharingP&P buses are flexible and will encourage hosted payloads/ride sharing.Hosted PLs will enhance affordability of space to a wide range of users. Short term some space companies will win & others will lose as space clients begin to seek out ride sharing agreements & resource sharing opportunities.Fiscal austerity may require that stakeholders economize and share resources to meet budget constraints.Multi-mission FlexibilityP&P bus -- mission flexibility exists within certain physical limits of power and mass. This benefit is not monetized in our analysis.US SIB could become more competitive internationally as CC increases manufacturing economies of scale and P&P bus allows for mission flexibility.NS stakeholders could benefit from flexibility in a world where threats and priorities constantly change.Reduced Build SchedulePartially Monetized -- P&P and CCs allow for compressing time between concept and delivery and ensures deployed systems are current.Ability to respond quickly to changing market priorities and customer’s requests.Defense & IC stakeholders seek new ways to respond quickly in new theaters.P&P Enabling InnovationPartially Monetized - P&P platforms allow for easier and less expensive technology insertion. Payload manufacturers can focus on innovation rather than NRE.Yes - US SIB outperforms competitors and regains space technology leadershipYes – NS stakeholders may use P&P platforms as test beds, prototypes and even replacements for expensive larger systems.Future Capabilities – Enhanced MonitoringA P&P bus generates Xteds data which can be used for better processing & detection for anomaly resolution. Longer term, a P&P bus is smart enough to handle autonomous operation.Enhanced Monitoring capability could provide competitive advantage to US SIB versus global competitors.A better understanding and ability to quickly identify anomalies enhances space situational awareness (SSA).Future Capabilities – High Data RateP&P bus could provide additional revenue streams as the P&P bus’s higher data rates allow for more bandwidth and as a result - additional revenues.Establishing well defined, high data rate interfaces within the spacecraft avionics could be a new capability enabler, and a competitive advantage. Also could attract global clients with established standards for higher data rates.It is possible that NS stakeholders may demand high bandwidth and rates for certain missions/applications.Industries Which Standardize Interfaces Often see Growth and Improved PerformanceCC = CQE Components; NS = National Security PL = Pay Load; P&P = Plug & Play; SIB = Space Industrial Base;

If acquiring products with closed interfaces, the PM will conduct a business case analysis to justifyacceptance of the associated economic impacts on total ownership cost and risks to technology insertion and maturationover the service life of the system.
27SUMOMIL-STD-1553SUMO proposes the development and implementation of a universal Architecture of Standards that will define the electrical and data interfaces for a satellite busMIL-STD-1553 is a military standard published by the US DoD that describes the method of communication and the electrical interface requirements for subsystems connected to the data bus.MIL-STD-1553 published as a US Air Force standard originally designed for use with military avionics.First used on the F-16 fighter aircraftLike 1553, SUMO will evolve starting with modular architecture requirements for satellite avionicsMIL-STD-1553A publishedMIL-STD-1553B publishedMultiple designs quickly followed including the F-18 and AH-64 ApacheMIL-STD-1553B released as a tri-services (Air Force, Army and Navy) standardThe SUMO industry consensus architecture of standards will develop within an international standards organizationSUMO will focus on the interoperability of the interfaces to provide flexibility and reliabilityMIL-STD-1553B adopted by NATO1993 – MIL-STD-1553B validated for use in acquisitionSeven change notices to the standard have been published since 1978Electrical interfaces explicitly specified to assure compatibility between designs by different manufacturersFlexibility without creating new designs for each new userExpanded international adoption into Europe and AsiaFollowing in the footsteps of aircraft pioneers, space industrialists are now ready for a more mature business model where expensive custom built space systems give way to universal satellite manufacturing standardsMIL-STD-1553 TODAYMIL-STD-1553 has evolved into the predominant, internationally accepted networking standard for the integration of military platformsMIL-STD-1553 has expanded beyond its traditional aircraft domain to encompass applications for combat vehicles, ships, satellites, missiles, and the International Space StationThe basic difference between the 1553A and 1553B revisions is that in the latter, the options are defined rather than being left for the user to define as required. It was found that when the standard did not define an item, there was no coordination in its use. Hardware and software had to be redesigned for each new application.
28Anecdotes from Industry Cost: Two manufacturers have stated that custom components are twice as expensive as standard components Focus on New Products: A component manufacturer stated that their existing products are already configurable to seven different primes – however, new products represent a “green field” opportunity to demonstrate interface standardization. Opportunity Costs and NRE: Many component manufacturers have stated that spending engineering resources for customizing interfaces is an opportunity cost – they would prefer to apply resources towards performance and innovation. Competitive Advantage: A component manufacturer indicated that they must design their products to fit almost 20 different interfaces . Their overseas competitor, on the other hand, has fully automated their production line – building to only two interfaces

An alternate model has Primes working to SUMO-ize their busses in parallel with component universalizaion and certification via IR&D or other new programs. Example: at least one prime is already at PDR maturity in implementing Space Wire (a likely SUMO sanctioned standard) in a POR as of This represents a significant move forward in SUMO-izing a prime’s bus. Under this scenario, there may be no cost upper for a proto-flight or POR; indeed there could be savings with use of SUMO-certified components that Plug-n-Play into Prime’s busses. Also, need to remember these programs will be competitive so Primes will be highly motivated to retire most if not all SUMO-izing NRE as a bid discriminator.
31Cost Savings ModelAerospace recently modeled the US satellite market to quantify the savings which may be achieved from “universal” components and from applying SpaceWire and SUMO.Variables include: capture rate, integration complexity, design compression, organizational complexity, rate of obsolescence and frequency of technology insertion, planned build quantity, and program length.Results indicate that billions of dollars can be saved.
