The Evolution of the CCSDS Orbit Data Messages

Abstract

The Consultative Committee for Space Data Systems (CCSDS) Orbit Data Messages (ODM) is undoubtedly the most successful and widely infused international standard developed by the CCSDS Navigation Working Group (NavWG). In 2004, the first version of the ODM was published after a development period of several years; before this, there was no CCSDS or ISO standard for the representation of a spacecraft trajectory. This paper will describe in detail the evolution of the CCSDS ODM through its several versions past, present, and future; its infusion into spacecraft operations in many if not most of the Earth's major space agencies; and some of the growing number of applications in which it is being utilized.
