How to Use This Calculator

Enter the initial orbit altitude (km) and desired final orbit altitude (km) above the central body.
Set the gravitational parameter (µ) for Earth (398,600 km³/s²) or another body.
Review the two required delta-V burns (ΔV₁ and ΔV₂ in km/s) and total ΔV.
Use transfer time (hours) and semi-major axis to plan mission scheduling and propellant loading.
