ISO 27852:2011 describes a process for the estimation of orbit lifetime for satellites, launch vehicles, upper stages and associated debris in LEO-crossing orbits.
ISO 27852:2011 also clarifies the modelling approaches and resources for solar and geomagnetic activity modelling; the resources for atmosphere model selection; and an approach for satellite ballistic coefficient estimation.
