Abstract
This paper describes the software developed at CNES within the context of the VESTA Franco-Soviet program, for the optimization of interplanetary trajectories. The sequentiel software, intended for the determination of multiple flyby trajectories and their optimization, was developed previously in collaboration with CNES and LAO of Paul Sabatier University, Toulouse, France. In this software, an impulse manoeuvre is performed at each flyby. The possibility to add an intermediate manoeuvre between flybys and the use of the swing-by aim to reduce the total trajectory costs. The optimization routines are parallelized.
This work was initiated and funded by CNES (French National Space Centre), Toulouse, contract 873- CNES-87-4937 between CNES and a previous structure of LAO, Paul Sabatier University. The work, except for the parallelization of the algorithms, has been carried out in collaboration with the Laboratoire d'Approximation et d'Optimisation (LAO), Université Paul Sabatier, Toulouse, France.
