This paper discusses the relevance of J2 effects induced by Earth’s oblateness on a tethered formation, when a massive cable model is included in the dynamic analysis of a multi–tethered satellite formation. The formations examined in this study are Hub-And-Spoke (HAS) and Closed-Hub-And-Spoke (CHAS) configurations for In-Plane and Earth-Facing spin planes. Some configurations present a cluster with deputies affected differently by the J2 potential depending on their initial position with respect to the orbital plane. The differences in stability, elongation of tethers and shapes of the formations under the J2 potential are compared with those in absence of the perturbation.

Abstract
This paper discusses the relevance of J2 effects induced by Earth’s oblateness on a tethered formation, when a massive cable model is included in the dynamic analysis of a multi–tethered satellite formation. The formations examined in this study are Hub-And-Spoke (HAS) and Closed-Hub-And-Spoke (CHAS) configurations for In-Plane and Earth-Facing spin planes. Some configurations present a cluster with deputies affected differently by the J2 potential depending on their initial position with respect to the orbital plane. The differences in stability, elongation of tethers and shapes of the formations under the J2 potential are compared with those in absence of the perturbation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
