B-PLANE VISUALISATION TOOL FOR UNCERTAINTY EVALUATION

Launchers used for interplanetary missions may be inserted into orbits in resonance with the Earth or that may to cross other planets' orbits. To verify the compliance with planetary protection requirements, the impact of the uncertainty on the trajectory evolution is assessed and two visualisations are produced. The first one is the common representation of the trajectory distribution on the Earth b-plane, highlighting also areas of gravitational interactions with other bodies. The second one represents a colour map of different states (i.e. impact with the Earth, resonances, interaction with other planets) on the grid of velocity variation used to define the initial conditions.
