摘要

This paper discusses an analysis of the behavior of a satellite pair to be used for a preliminary observation campaign design for the New Worlds Observer (NWO) mission concept. NWO seeks to collect direct observations of exoplanets using two vehicles: a telescope and a Starshade occulter, located thousands of kilometers apart. In this concept, the two NWO spacecraft are positioned in halo orbits about the Sun-Earth L2 point. This study shows the behavior of the NWO's observation vector that may be used to redirect NWO's observation from one star to another using dynamical systems theory, taking advantage of the non-linear dynamics around L2. This paper shows an overview on the behavior of both the constraints as well as the pointing vector of NWO on a sky map depending on the chosen configuration.
