Abstract:

This paper details the development of analytical approaches and procedures to reasonably determine orbit lifetimes for post-mission orbits, accounting for nonlinearities of solar and geomagnetic indices, solar cycle phasing, drag coefficient variations, orbit-to-Sun geometry variations, and the recently observed thermospheric cooling effect. These techniques were originally developed to support the development of a draft standard for the International Standards Organization (ISO) to help reduce long-term collision risk in the LEO orbit regime by ensuring that the pre-launch assessment of orbital lifetime is done carefully and accurately, using standardized analysis methods.
