Center For Space Standards & Innovation


Acting as a central resource for open, readily available, industry-wide standards, CSSI continues to test and evaluate industry practices to determine where standardization is needed. In terms of the space enterprise, CSSI suggests that "characteristics of the physical environment be standardized, but not the physics. Data exchanges should include measures of accuracy and precision. In particular, covariances are absolutely essential for effective interaction within astrodynamics." (Dr. David Finkleman, Standards, Rules, Innovation, and Inhibition)

Why should astrodynamic standards exist?

Primarily, standards exist because they encourage uniformity, common practice, and interoperability. Traditionally, astrodynamics standards have been simply a compilation of equations with little information on how to piece them together.

National and international standards generally describe what to do, not how to do it. Industry standards are the consensus of experts throughout the world. Adhering to standard confers instant credibility for the user’s products. Standards should not teach, but rather consolidate information so the user can easily determine a minimum baseline that will yield acceptable results.
(Excerpts from David A. Vallado, A Summary Of Astrodynamic Standards)

Proposed definition of astrodynamic standards:

Astrodynamics standards are processes and practices that, by consensus of the world or national industrial and academic communities, best promote interoperability, information exchange, and commerce.
