  1. Battle Damage Assessment: Space Mission Design Process Example

  2. Mission Statement • Warfighters need near real-time battlefield recon to conduct bomb damage assessment following tactical sorties to redirect air resources as needed to complete operational missions • Air recon missions face too many hazards to perform the assessment safely

  3. Pre-strike Post Strike The Mission

  4. The Mission

  5. Step 1: Define Mission Objective(s) • Primary: To detect and assess battle damage anywhere in the world in near real-time • Secondary: To provide surveillance capabilities to the DoD that will verify treaty compliance • Secondary: To provide damage assessment of natural disasters to relief agencies throughout the world

  6. Step 2: Preliminary Mission Requirements and Constraints • Wavelength Range: 0.6 – 1 mm • Resolution: 5 m • Swath Width: 200 km • Pointing Stability: 1 km • Latitude Coverage: ± 90° • Satellite Lifetime: 5 years • Reliability: 95% Operational Availability • Coverage: 70% with 2 hr maximum gap

  7. Resolution

  8. Swath Width

  9. Pointing Stability

  10. Step 2: Preliminary Mission Requirements and Constraints • Months to IOC: 42 months • Total Budget: $241,000,000 • All DoD acquisitions will follow DoD 5000 standards (regulation) • System must communicate with existing air, ground and sea assets via the JWICS architecture (external interface) • These constraints can produce derived requirements…

  11. Step 2: Preliminary Mission Requirements and Constraints • Operations: Shriever AFB, CO • Mission Ops: $10,000,000 / year • Existing G/S to be used • G/S Reciever Bandwidth: 10 MHz • S Band Downlink: 2.3 GHz

  12. Step 3: Alternative Mission Concepts • Large constellation (10-15 satellites) of small satellites in low-Earth orbit • Medium constellation (5-7 satellites) of large satellites in low- to medium-Earth orbit • Small constellation (3 satellites) of very large geosynchronous satellites • Near space assets (lighter than air) in the Stratosphere

  13. Step 3: Alternative Mission Concepts • On-board data compression scheme for images • Full raw data transmission • Send data directly to commanders in the field • Send data to Pentagon (or some other central location) for analysis
