Abstract:
This paper describes the Dynamics, Kinematics, and Environment (DKE) modeling approach devised for the DFACS-L3GWO study for Phase A/B1 of the LISA mission. By measuring the very small displacement of the so-called test masses within 3 spacecraft, separated by 2.5 million km, in a rotating triangular formation, 50 million km from the Earth, this mission is set to be the first gravitational wave observatory in space. One of the major challenges in modeling such physics is the uniquely large difference, in orders of magnitude, of the states whose time-evolution is to be described. The formulation proposed addresses specifically this issue, while also considering a wide range of disturbances, including the influence of bodies in the solar system in the overall stability of the satellites formation. The work described herein paved the way for the design and verification of the GNC subsystem, also developed within the DFACS-L3GWO study.
