public class Sgp4ElementsSwitchByMidpoint
extends Sgp4ElementsSwitching

An algorithm which determines when to switch from one element set to another by comparing their respective Epoch (get / set) values. The first element set is used up until the midpoint in time between the epoch of the first and the epoch of the second. The last element set is used from the midpoint in time between its epoch and the epoch of the set before it.
