A method for handling coast arcs for low-thrust interplanetary trajectory optimization is presented. The method combines a switching function with the guessing of the length and center point of the coast arc. The center point of the coast arc is shifted while its length is held constant while the values of the switching function at the start and end of the coast arc are made equal. Then the length of the coast arc is found directly through a linear extrapolation procedure. Then the optimal center point for the coast arc is found. Examples of the procedure based on low-thrust earth-Jupiter trajectories are presented.
