Here, we define an orbit and then plot it with several different maneuvers applied.
Note: Plotting an orbit with a maneuver doesn't apply the maneuver to the original orbit.
In [3]:
orbit1 = KeplerianElements.with_altitude(1000 * kilo, body=earth)
In [4]:
man1 = Maneuver.set_apocenter_altitude_to(10000 * kilo)
plot(orbit1, title='Maneuver 1', maneuver=man1)
In [5]:
man2 = Maneuver.set_apocenter_radius_to(22000 * kilo)
plot(orbit1, title='Maneuver 2', maneuver=man2)
In [6]:
man3 = Maneuver.set_pericenter_radius_to(6800 * kilo)
plot(orbit1, title='Maneuver 3', maneuver=man3)
In [7]:
man4 = Maneuver.set_pericenter_altitude_to(500 * kilo)
plot(orbit1, title='Maneuver 4', maneuver=man4)
In [8]:
man5 = Maneuver.change_apocenter_by(1000 * kilo)
plot(orbit1, title='Maneuver 5', maneuver=man5)
In [9]:
man6 = Maneuver.change_pericenter_by(-500 * kilo)
plot(orbit1, title='Maneuver 6', maneuver=man6)
In [10]:
man7 = Maneuver.hohmann_transfer_to_altitude(10000 * kilo)
plot(orbit1, title='Maneuver 7', maneuver=man7)
To apply a maneuver, simply use the following method:
In [11]:
orbit1.apply_maneuver(man7)
Now orbit can be plotted to show its new state:
In [12]:
plot(orbit1, title='Applied Maneuver')
