 | Senior leadership of the Air Force's Space and Missile Center suggested an investigation of systems integration within the space acquisition community in the fall of 2008. This thesis performs that investigation. A review concluded that while Systems Integration (SI) is extensively discussed as an area deserving considerable attention in the Systems Engineering literature, definitions are weak and methods and tools non-existent. Known SI activities are not being traced and assessed ... |

| DOD's major space system acquisition programs are intended to perform a wide variety of functions, including communications, missile warning, navigation, tracking space objects, and even providing weather information. Communication satellites provide DOD the ability to communicate along narrowband, wideband, and secure and protected bandwidths. Narrowband communications use lower (slower) rates to process data and give the warfighter the ability to communicate better while on the move, and also work better ... |

Peter Hantos; AEROSPACE CORP EL SEGUNDO CA SYSTEMS AND COMPUTER ENGINEERING DIV
|
| Modern weapon systems (including all space systems) are software-intensive, technology-driven systems; consequently, the early evaluation of software technologies is critical. Service Oriented Architecture (SOA) is a promising approach to implement Operationally Responsive Space (ORS) and Joint Warfighting Space (JWS). SOA qualifies as a Critical Technology Element (CTE), and as such requires a rigorous Technology Readiness Assessment (TRA) inquiry. |

| Estimated costs for the Department of Defense's (DoD) major space acquisition programs have increased by about $12.2 billion from initial estimates for fiscal years 2006 through 2011. Cost growth for ongoing Air Force programs above initial estimates accounts for a substantial portion of this 44 percent increase. In light of the role that optimistic estimating is believed to have played in exacerbating space acquisition cost growth, the Congress requested that ... |

| Free space optics "FSO" can provide high data rates with efficient use of power. However, small platforms may not be able to support the payload requirements of a conventional FSO terminal. An alternative FSO terminal uses a modulating retro-reflector "MRR". MRRs shift most of the power, weight, and pointing requirements to one end of the link. With a MRR configuration, it is possible to establish a two-way FSO link using ... |

| FPGAs are finding an increasing number of applications within NASA in deep space probes, planetary rovers and manned vehicles. Like other silicon devices, FPGAs can be damaged by high energy cosmic ray impacts, resulting in permanent latch-up conditions that manifest as stuck-at faults. Traditionally, multiple redundancy and voting logic have been employed as a work-around, particularly for high reliability, extreme environment applications. However, reconfigurable FPGAs are becoming increasingly common in ... |
