I have to design a space mission to Saturn as part of a course on spacecraft and system engineering. I found a suitable trajectory but, as the Δv is quite high, I would like to adapt it to Ion propulsion.
What are the proper assumptions I have to do to make it "realistic" for low thrust propulsion? How can impulse thrust trajectory be adapted to a low thrust system?
The simplest would probably be to find a trajectory with multiple gravity assists, like Cassini did (EVVEJS), but since this is just an assignment project, I haven't the tools nor the time to compute such a trajectory.
