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