Plane Change Optimizer
Estimate impulsive delta-v for rotating between orbital planes. The calculation supports pure inclination changes and combined inclination plus RAAN changes.
Delta-v
3.8400 km/s
3,840.0 m/s
Plane angle
28.500 deg
between initial and final orbital planes
Orbital plane rotation
Plane-change cost scales with burn speed.
28.50 deg between planes
7.800 km/s
3.840 km/s
0.492
Delta-v burden
3,840.0 m/s
49.2% of the local orbital speed.
Why low speed helps
Plane-change cost scales with burn speed, so performing the rotation near apoapsis can reduce delta-v.
