What Is the Hohmann Orbital Transfer Delta-V Budget & Flight Time Calculator?
The Hohmann transfer is the most fuel-efficient two-impulse maneuver for transitioning a spacecraft between two coplanar circular orbits.
An initial burn injects the satellite into an elliptical transfer orbit, and a second apogee burn circularizes it at the target destination.
