Synopsis
The presentation “NASA Small Satellite Cost Estimating Presentation 2020” provides a comprehensive overview of cost estimation for small satellite (smallsat) and microsatellite missions. Here’s a summary of its key contents:
Introduction and Background
- The document begins with a discussion of the history and evolution of small satellite cost estimating, which has a record dating back approximately 25 years, involving both NASA and Department of Defense missions. The technology and context for smallsats have changed significantly over this period, with increased utilization and technological advancements.
Definitions and Scope
- It defines small satellites, microsats, and cubesats in terms of their weight and mission costs, acknowledging that these definitions vary across different projects and organizations.
Cost Estimating Basics
- The presentation delves into the fundamentals of cost estimation, focusing on NASA’s Work Breakdown Structure (WBS), which is a standard approach used in their projects. It outlines the various elements of WBS, including project management, systems engineering, mission assurance, and more.
Cost Estimating Methods
- Three primary cost estimating methods are discussed: analogy, parametric, and grassroots. Each method has its advantages and disadvantages, depending on the specific requirements and context of the mission.
Detailed Cost Model Overviews
- The document provides an in-depth look at various cost models available to the NASA community, including the NASA Instrument Cost Model (NICM), Project Cost Estimating Capability (PCEC), PRICE True Planning, and the Small Spacecraft Cost Model (SSCM-19). Each model is described in terms of its features, data inputs, and specific uses.
Case Studies and Examples
- Several examples of cost estimation are provided, including analogies for small spacecraft buses and parametric estimates for flight software costs.
Cost Estimation for CubeSats/Microsats
- A significant portion of the presentation is devoted to cubesats and microsats, including the introduction of the NASA CubeSat or Microsat Probabilistic Analogy Cost Tool (COMPACT). This section discusses the specific needs and challenges in cost modeling for smaller spacecraft.
Recommendations and Conclusion
- The document concludes with key recommendations for effective cost estimation in small satellite missions. It emphasizes the importance of realistic assessments, seeking help when needed, understanding cost parameters, and defending cost estimates with a strong basis.
Questions and Additional Resources
- The presentation ends with a section for questions and references additional resources and contact information for further inquiry.
This document serves as a detailed guide for professionals in the field of satellite mission planning and cost estimation, particularly those focusing on small and microsatellite missions.
