Finite burn

WebA finite burn model, as opposed to the idealized impulsive burn model used for preliminary design, is needed to accurately model actual spacecraft maneuvers. In this tutorial, we will use GMAT to perform a finite burn for a spacecraft in low Earth orbit. The goal of this finite burn is to achieve a certain desired apogee radius. http://freeflyer.com/_help_Files/finiteburn_nanosecond.htm
