National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Functional Cost-Estimating Relationships for Spacecraft.

ADA308665

Publication Date	1996
Personal Author	Om, N. I.; Roth, J. K.; Corso, M. L.; Titus, J. A.
Page Count	82
Abstract	The Ballistic Missile Defense Organization questions the use of traditional weight-based spacecraft cost models developed by the Air Force Space and Missile Systems Center. The concern is motivated by changes in satellite designs of future systems where smaller but more capable spacecraft are being built. IDA developed spacecraft functional (engineering and manufacturing) cost-estimating relationships (CERs) at the spacecraft subsystem level using performance and physical characteristics that are not primarily weight-based. We developed nonrecurring (design, development, and test) and recurring (production) CERs for the spacecraft bus, including ground support equipment, and for communications payloads. The CERs show that programmatic aspects, which reflect the requirements and acquisition environments that the satellites were acquired under, have considerable influence on satellite costs.
