Beschreibung:

A bi-elliptic transfer from a low circular starting orbit (dark blue), to a higher circular orbit (green). The spaceship is traveling in a counterclockwise direction during all segments of the orbital transfer as is indicated by the blue and green arrows. When the spacecraft arrives at point 1 it performs a prograde burn to enter the first portion of the transfer orbit (red segment). It then coasts until apoapsis of this transfer orbit located at point 2 where another prograde burn is performed to raise the point of periapsis until it coincides with the orbital radius of the desired orbit. The spacecraft then turns off its engine again and coasts along the orange segment until it arrives at point 3. The maneuver is completed by performing a retrograde burn at point 3 to slow the spacecraft down and lower apoapsis until the orbit is circular again. The image shows exactly computed trajectories of a bi-elliptic transfer with a ratio of orbit radii of 14, where the apoapsis is 26.10 times the smaller orbit radius. In this case the transfer is as efficient as a Hohmann transfer, for larger apoapses it is even more efficient. Source code below.
