Available in PDF, EPUB and Kindle. Book excerpt: Historical costs from 11 unmanned satellite programs were analyzed. From these data, total satellite cost estimating relationships (CERs) were developed for use during preliminary design studies. A time-related factor, which it is believed accounts for differences in technology, was observed in the data. Stratification of the data by type of payload was also found to be necessary. Cost differences that stem from production quantity variations were accounted for by adjustment factors developed from standard learning curve theory. An example to illustrate use of the CERs is provided.

Available in PDF, EPUB and Kindle. Book excerpt: Why have the costs of acquiring space systems been so high? What are the sources of the problems? To answer these questions, RAND researchers examined the sources of cost growth of Air Force space systems and undertook an extensive study of two space systems--the Space Based Infrared System-High (SBIRS) and the Global Positioning System (GPS)--including an evaluation of their sources of cost growth, an assessment of their approaches to technical risk assessment, and an examination of their acquisition policy adaptations and industrial base environments. The researchers recommend independent program assessment for space systems that emphasizes technical and program factors, and a modified organizational structure that maintains cost analyst independence. They also summarize the cost estimating best practices of several other government organizations.

Available in PDF, EPUB and Kindle. Book excerpt: In response to historically high cost growth in the acquisition of space systems, the Under Secretary of the Air Force, in accordance with National Security Space (NSS) Acquisition Policy, directed the Air Force acquisition community to support the development of independent, accurate, and timely cost analyses to make the acquisition of NSS systems more realistic in terms of estimated costs. In turn, the former commander of Air Force Space Command (AFSPC), Gen Lance W. Lord, and the former commander of the Air Force Space and Missile Systems Center (SMC), Lt Gen Michael Hamel, asked RAND Project AIR FORCE to assess cost-estimating requirements and capabilities of SMC cost-estimating organizations as well as their resources, tools, methods and processes and to recommend an enhanced approach to cost analysis aimed at improving cost-estimating for space systems and increasing the understanding of factors that influence their cost. The study was sponsored by the former commander of SMC, General Hamel. The project technical monitor was Col Delane Aguilar, SMC/FMC. The research was conducted within the Resource Management Program of RAND Project AIR FORCE as part of a multiyear study entitled Air Force Space Systems Costs. The initial data collection was completed in May of 2006 and the final update was provided in February of 2007, with frequent updates in between. The final briefing was presented to General Hamel on March 13, 2007, and to Gen Kevin P. Chilton, the former commander of Air Force Space Command, on March 21, 2007. This monograph should interest government personnel involved in cost estimation and acquisition of defense systems, the military space acquisition communities, and those concerned with current and future acquisition policies.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this monograph is to test some of the CER's in the Unmanned Spacecraft Cost Model for non-constant error variances, or heteroskedasticity, and to take corrective statistical action if and where the problem is found. The Unmanned Spacecraft Cost Model is a set of regression equations or Cost Estimating Relationships (CER's) designed to explain the costs of spacecraft subsystems, such as electrical power supplies, apogee kick motors, and communication electronics. Technical and performance characteristics are used to explain costs, with the model based on 35 military, communications, weather, experimental, and lunar-probe spacecraft. The model presents equations for explaining both first-unit recurring costs and total nonrecurring costs, using 'normalized' and 'unnormalized' data. This paper, the first of five statistical monographs on the spacecraft model.

Book excerpt: The costs to acquire space-based missile defense systems are often reviewed by DoD. Issues are raised concerning the cost models used to generate cost estimates for space-based missile defense systems. 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. Using weight-based cost models yields lower cost estimates, although the spacecraft are more capable. 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.
