303-977-5066 11 EELVEELV –– Secondary Secondary PayloadPayload (SP)(SP) CapabilitiesCapabilities • Secondary Payload Benefits • Philosophical Approach for SPs • SP Issues • SP Interface Control Doc (ICD) • SP System Integration • Mission Concept Summary • SP Carrier - Details • Mission Opportunities Near Term • Progress Summary

STP-1 22 PhilosophicalPhilosophical ApproachApproach forfor SecondariesSecondaries • Dedicated focus on primary mission customer – Primary retains schedule, manifest, DOL authority – Primary is completed prior to SP separation (w/exception) – Primary integration, launch, and mission – not impacted by SP – SPs plug and play swap-ability – no impact to DOL • Robust design capability for flexibility – SPs dynamically isolated from primary to maximum extent possible – Kit-able SP standard interface and simplified ops design – Add/Removable SP platforms as margin is released – Enveloping qualification specs for SPC/SP in ICD/user guide • Low-risk Integration – SP will test-like-you-fly, electrical/mechanical I/F c/o (use of the ULA SIL) – Primary/SP integration in parallel separate facilities – Primary/adapter integrated atop populated SPC in P/L processing facility (PPF) prior to encapsulation and transport to launch pad

SPs rideshare to where the primary is going

33 SPSP IssuesIssues • Primary payload’s willingness to fly SPs • Launch vehicle team has a risk aversion mind-set • SPs electrically quiescent from encapsulation thru primary mission • Establish enveloping SP specs for Loads Analysis • Include lessons learned from STP-1 – EMI effects from motorized sep systems – Must do “test-like-you-fly” in the SIL – too costly an integration process • Need for defined SP qualification methodology and certification • Still In-Work: – SPC, pPod structural designs & load limits are preliminary – Electrical I/F trade study (simplify avionics for recurring integration) – Enveloping environmental standard and separation shock limits • Need for a “clearing house” to do mission integration to certify interface accommodation and qualification for small payloads Need for a gov’t agency to manage mission integration

44 SPSP InterfaceInterface ControlControl DocumentDocument (ICD)(ICD) • ICD will have enough material to act as a Users Guide to the SP community • Enveloping guides for mass/volume/cg • Separation clearances, spin rate, tip-off rates • Sep device qualified to allowable shock environment • RF environments and interface limitations • Trickle charge and power availability in-flight • Telemetry availability w/ 422 I/F • Events controls and verifications • Qual environment standards, Qual certification guide

The ICD will act as a Users’ Guide

66 SPSP SystemSystem IntegrationIntegration LabLab (SIL)(SIL) • To run a SP Integration verification we need to test – from the ground system to the SP, – from the Atlas Vehicle Avionics to the SP – track and analyze TLM from the SP • The CFA provides all the SP standard cabling – electrical I/Fs (power, A/B sequencing) using a CRCU – MDU provides TLM data interleave via 422 I/F SP • Avionics-SIM provides A/B events Integration • Gnd H/W interfaces provides power & umbilical

• CCLS will sequence thru ground tests I/F Chassis A/B cables • ADMS provides operator stations CRCU Uplink/ – TLM monitoring, TLM archive data Downlink 422 (100 baseT) Centaur • PCs to port customer SP sw for testing Forward Adapter (CFA) The SP-SIL will help you get ready to fly DET

CCLS FTINU Computer Electrical Controlled Equivalent ADMS ADMS PC PC Launch Set (customer stations) 77 SPsSPs MissionMission ConceptConcept SummarySummary • STP-1 released a primary and 5 SPs – Orbital Express (primary) with MidStar-1 at 492km circular, 46 deg incl – NPSAT1, STPSat-1, CFE, FalconSat-3 at 560km circular, 35.4 deg incl – STP-1 had 6000 lb of unused performance margin • Most commercial launches are GTO – Approx. at 27 deg w/ a retrograde orbit that is either + or – a ½ deg. – Perigee is nominally 185 nm up to 300 nm – Apogee is GTO up to 100k nm – Upper Stage do degrade over time. – Tend to circularize at perigee & gradually lower till extinction. – The lower the perigee – the faster they decay

This is where we are typically going

1717 Type-CType-C CarrierCarrier (TCC)(TCC) [Atlas[Atlas && Delta]Delta] • ’06 Study found placement of up to 4 TCCs to have no impact to EELV or commercial launches. – Mounting brackets for the Carriers will be added to the C22. (Stress analysis may require additional adapter structure mods) – No impact to the GSE Isolation Diaphragm with placement of the Carriers above the C22 mid ring. – Study analysis used shock isolators 58-77628-9 (ST54D59-8) already in use in the payload area. • Design Goals: – Brackets to be standard hardware on the C-adapter – TCC modes to be enveloped to have no impact on Primary – Stiffness design to permit enveloping the loads-analysis allowing late integration as weight-margin is made available – Avionics to be kit-able, event-table to be standardized
