Generic Launch Window Analyzer SW2M - Applicability to Rideshare Payloads

The aim of this IRAD is to build upon the generic launch window analyzer that has been developed under previous IRADs so as to allow it to be applied to rideshare missions, where a secondary spacecraft makes use of the excess performance capability of current launch vehicles.  One example of this excess performance is afforded by the launch of Landsat-8 on an Atlas V: in order to dispose of the Centaur stage after launch, it was not deorbited, but rather injected into a heliocentric escape trajectory.
