A method to make a rapid prelaunch estimate of near earth satellite lifetimes using small perturbation theory is presented. A quasi-dynamic atmospheric model is used by employing a different exospheric temperature every three months. The drag coefficient is calculated using kinetic theory. The method is validated by application to several known satellites and is then used for a proposed Brazilian satellite.
