Oral presentation at the conference
A sequential algorithm for optimizing low-thrust Earth orbit transfers in terms of the propellant consumed is proposed. The dynamical model includes the effect of the Earth shadow and the J2 effect of the gravitational potential. The algorithm is based on two steps of growing complexity. In the first step, a near-optimal solution is obtained using simplified dynamics. In the second step, a...

Oral presentation at the conference
The demand for deep space missions and the desire to investigate small space objects like asteroids and comets is increasing constantly. Such exploration missions open up the possibility to gain further scientific knowledge about the origin of our solar system as well as to find and eventually mine rare earth elements that are narrow on Earth or even to discover novel resources.
To realize...

Oral presentation at the conference
Gravity-assist maneuvers have the potential to be mission enablers, due to ""free energy"" they provide. The efficiency of low-thrust propulsion is further one means of improving mission payload mass. Combining both for a given mission possibly improves overall mission performance, which makes it desirable to investigate low-thrust gravity-assist missions.
For means of investigating a...

Oral presentation at the conference
On behalf of future missions with electric propulsion controlled by DLR’s German Space Operations Center (DLR/GSOC) the present operational multi-mission Flight Dynamics System (FDS) is enhanced to support the preparation and operation of corresponding satellite missions.
For designing an easily extendable framework, low-thrust scenarios including orbit raising to GEO, GEO station keeping...

The paper describes the general strategy for electric propulsion orbit transfers, a open source optimiser for orbit transfer based on averaging techniques and the integration of such trajectory optimiser into EcosimPro® ESPSS (European Space Propulsion System Simulation). EcosimPro® is a Physical Simulation Modelling tool that is an object-oriented visual simulation tool capable of solving...

Oral presentation at the conference
In this work a toolbox for the fast preliminary design and optimisation of low-thrust trajectories is presented. The toolbox, called CAMELOT (Computational-Analytical Multi-fidelity Low-thrust Optimisation Toolbox), solves highly complex combinatorial problems to plan multi-target missions characterised by long spirals including different perturbations. CAMELOT implements a novel...
