10th Global Trajectory Optimisation Competition

GTOC X Homepage

The 10th edition of the Global Trajectory Optimisation Competition, GTOC X, is being hosted in 2019 by the Mission Design and Navigation section at the Jet Propulsion Laboratory. GTOC was started in 2005 by Dario Izzo of the European Space Agency’s Advanced Concepts Team as a way to foster innovation in optimization of interplanetary trajectories and cross-fertilization of ideas between researchers in optimization and in astrodynamics.

We invite all interested researchers or teams of researchers to register to compete in GTOC X.
