【 摘 要 】

Earth and other planets gravitational fields induce perturbations of the (e)LISA constellation geometry (mostly flexing and Doppler frequency shifts). We present here a numerical optmization method minimizing these distrubances, subject to constraints (maximum distance to Earth and launch mass).
