Progress in International Space and Astrodynamics Standards

摘要

This paper will report progress in standardizing important elements of astrodynamics analysis. Via the International Standards Organization (ISO) and its associated processes, international standards will build from fundamental astrodynamic analysis practices to standards for assessing conjunction probabilities, orbit lifetimes, launch collision avoidance and space debris evolution. It has been difficult to achieve international consensus on elements of astrodynamics. We will discuss our experience drafting international standards for sharing orbit data, for describing the manner in which orbits are estimated, for performing conjunction assessment, and for determining orbit lifetimes. We solicit feedback from the astrodynamics community and contributions to the goal of world-wide understanding and collaboration.
