| Description: | Previous studies have shown that disposal orbits for the medium Earth orbit constellations can be unstable and undergo significant long-term eccentricity growth. This can lead to repenetration of the constellations by disposed vehicles, thereby posing a collision risk. The study presented here investigated the possibility of diluting disposal orbit collision risk by exploiting long-term eccentricity growth. The Galileo constellation was selected as an example. Various disposal strategies were considered. It was found that high eccentricity growth strategies can reduce the combined constellation and intra-graveyard collision risk relative to a minimum eccentricity growth strategy. |
