Executive Summary Background
  • Orbital Aggregation Space Infrastructure
    Systems (OASIS) is an in-space architecture
    concept consisting of highly reusable systems and
    resources that provide a common infrastructure
    for enabling a large class of space missions
  • FY01 RASC studies focused on preliminary design
    of OASIS elements and analysis of Lunar Gateway
    and commercial mission scenarios
  • This study package summarizes results of FY01
    OASIS commercialization analyses
  • OASIS capability and potential commercial markets
    (traffic model)
  • Economic viability analysis
  • Preliminary costing of OASIS elements

Hybrid Propellant Module

Executive SummaryResults
  • OASIS Commercial Traffic Models
  • OASIS performance has been evaluated for
    commercial satellite applications
  • OASIS commercial traffic models have been
    developed based on satellite delivery considered
    the floor for potential commercial
    applications
  • Future DoD missions may provide additional OASIS
    applications/usage rates
  • OASIS Economic Viability
  • HPM/CTM has commercial potential when used as an
    orbital transfer stage in conjunction with alow
    cost booster to LEO at flight rates greater than
    3 per year per HPM/CTM
  • OASIS commercial viability is highly sensitive to
    infrastructure costs, mission rates and
    Earth-to-LEO launch costs

purposes only and does not constitute a

Overview and Assumptions
  • Objectives
  • Assess OASIS applicability and benefits for
    Earth Neighborhood commercial and DoD space
    missions in the 2015 timeframe
  • Determine key needs for projected commercial/DoD
    missions that OASIS may support (e.g.,
    deployment, refueling/servicing,
    retrieval/disposal)
  • Quantify levels of potential commercial
    utilization and develop ROM estimates for
    economic impacts
  • Study Drivers
  • Projected commercial/DoD satellite market
  • OASIS design (sizing, performance)
  • OASIS allocation to support identified markets
    (traffic models)
  • ETO transportation costs (trades vs. non-OASIS
    architectures, cost of resupply propellant)
  • Assumptions
  • Scenarios utilize OASIS elements defined for
    Exploration missions using performance masses
  • A low cost Earth-to-LEO transportation capability
    is required
  • Highly reliable RLV or ELV for sensitive cargo
  • Lower cost LEO delivery system for propellant
    resupply
  • Industry adopts common infrastructure (e.g.,
    attach fittings, refueling ports, plug-and-play
    avionics)
  • Goal - Maximize potential commercial
    opportunities (i.e., Greatest number of
    satellites deployed/serviced with minimum number
    of OASIS elements)

Satellite Market Trends -
Comstac Futron Studies
  • Commercial
  • NGSO market estimates fluctuating, trends
    volatile
  • GEO launch demand fairly constant ( gt30/year)
  • Spacecraft mass growth continues - especially
    heavies ( gt5,445 kg)
  • Spacecraft trend toward electric propulsion
  • Commercial launch demand trends
  • Consolidation of spacecraft manufacturers/owners
  • Increasing on-orbit lifetime
  • Business conservatism for financing projects
  • DoD
  • DoD applications difficult to identify programs
    under definition
  • Trend toward greater value and functionality per
    satellite unit mass initial picosatellite
    experiments have been completed
  • AF Science Advisory Board distributed
    constellations of smaller satellites offer better
    prospects for global, real-time coverage and
    advantages in scaling, performance, cost, and
    survivability
  • Potential for very large antenna arrays for
    optical and radio-frequency imaging utilizing
    advanced structures and materials technologies

Analysis Assumptions
  • Market
  • Future NGSO constellations will exist in similar
    orbits as recently envisioned
  • Launch Vehicle
  • Delivers payloads to 400 km circular parking
    orbits at inclination (inc) and right ascension
    (RA) of stored OASIS elements closest to final
    orbit
  • HPM
  • A propellant reserve provides 150 mps velocity
    reserve for maneuvers (e.g., rendezvous,
    proximity operations and docking, reboost in
    storage orbits, etc)
  • CTM
  • HPM chemical engine applies DV impulsively at
    locally optimal orbit locations
  • Perigee and Apogee (i.e., Hohmann transfers) for
    altitude variation
  • Node crossings for inclination changes
  • Nodal complement locations for right ascension
    changes
  • Propellant is available to autonomously
    pre-position to HPM rendezvous point as necessary
  • SEP
  • Not considered in analyses due to mission
    duration impact and refurbishment costs
  • Satellite
  • Satellite battery life available for 2 days
    autonomous operation between LEO delivery and HPM
    docking and mission completion - Boeing
    Satellite Systems concurs

NGSO Analysis Results
  • Initial analysis
  • For each satellite in current market
  • Calculate DV required for delivery and return
  • Compare DV to HPM/CTM capability
  • Adjust HPM/CTM inclination and orbit planesto
    improve performance
  • Results
  • Only 14 of 27 constellations deployable
  • Need 3 constellations, total of 30 HPM/CTMs (10
    in each constellation)
  • Revised analysis
  • For each satellite
  • Recalculate DV required without Right Ascension
    plane change
  • Compare with HPM/CTM capability
  • Compute nodal alignment phase time
  • Results
  • 24 of 27 constellations deployable
  • Need 2 constellations, total of 18 HPM/CTMs
  • Launch windows occur within 30 days

22
NGSO Traffic Model Conclusions
  • HPM/CTM Constellation Allocation
  • Most of the current suite of commercial/military
    constellations are deployable/serviceable
  • Requires one constellation of 8 HPM/CTMs near
    ISS inclination
  • Requires one constellation of 10 HPM/CTMs near
    polar inclination
  • Planar launch window opportunities within 30
    days
  • MEO satellites (e.g., GPS) are delivered to
    transfer orbits using near ISS HPM/CTMs

OASIS Integrated Traffic Model
Traffic model variation is based on satellite
lifetime extremes
Lifetime Estimates 5 years 10
years
  • Refined commercial traffic model based on
  • Higher usage rate missions only (gt 3 flights per
    HPM per year)
  • Single launch site from ETR to eliminate
    duplication of ground infrastructure (excludes
    polar servicing)
  • 50 market share (of high traffic model)

Commercialization Study OASIS Economic
Viability Analysis
26
OASIS Economic Viability Analysis Overview
  • Objective
  • Provide a preliminary economic viability
    assessment of HPM/CTM in future commercial
    satellite deployment/servicing markets as defined
    by the integrated traffic model
  • Approach
  • Compare potential life cycle earnings over range
    of critical economic factors
  • Identify economic factors with strong influence
    on earnings
  • Determine the economic sensitivity and establish
    hurdle values for these critical factors
  • Earning levels necessary for economic viability
    include allowance for non-recurring start up
    costs
  • Start up costs per HPM/CTM include HPM/CTM
    procurement (ROM estimate 150 million each),
    and initial launch, development and deployment of
    commercial peculiar infrastructure (e.g., HPM
    propellant processing facilities)
  • Start up costs per HPM/CTM assumed not to exceed
    500 million actual value varies inversely with
    fleet size
  • Industry leverages government investment in
    infrastructure development

27
Identification of Critical Economic Factors
  • Critical Economic Factors
  • Charge to deploy satellite to operational orbit
  • Propellant delivery cost to LEO ( per kg)
  • Payload (satellite) cost ( per kg) to LEO
  • HPM/CTM use rate
  • Life cycle earnings
  • Ch
  • Prop
  • P/L
  • R
  • Definition
  • Total charge to customer to deploy their
    satellite
  • Establishes cost to resupply HPM with full load
    (32,000 kg) of propellant per deployment
  • 5,000 kg payload, calculated at twice the /kg
    as propellant
  • HPM/CTM flights per year (based on traffic model
    analysis)
  • LCE Ch - (Prop P/L)R10 year HPM/CTM life
