Space systems. Estimation of orbit lifetime. | Status: Current

1 Scope This document describes a process for the long-duration orbit lifetime prediction of orbit lifetime for spacecraft, launch vehicles, upper stages and associated debris in LEO-crossing orbits after mission phase (including any mission lifetime extensions). The document also clarifies:

1. a) modelling approaches and resources for solar and geomagnetic activity modelling;
2. b) resources for atmosphere model selection;
3. c) approaches for spacecraft ballistic coefficient estimation.
