// this program solves the Hohmann two impulse orbital transfer
// between planar and non-coplanar circular Earth orbits

////////////////////////////////////////////////////////

This program will request the altitude and orbital inclinations of the initial and final orbits with the following prompts. Please note the proper units for each input.

// request altitude of initial circular orbit (kilometers)

INPUT(alt1, "Hohmann transfer", "alt1 = ", "enter initial altitude in kilometers");

// request altitude of final circular orbit (kilometers)

INPUT(alt2, "Hohmann transfer", "alt2", "enter final altitude in kilometers");

// request inclination of initial circular orbit (degrees)

INPUT(inc1, "Hohmann transfer", "inc1 = ", "enter initial inclination in degrees");

// request inclination of final circular orbit (degrees)

INPUT(inc2, "Hohmann transfer", "inc2 = ", "enter final inclination in degrees");

A PDF document which describes the orbital mechanics of the Hohmann transfer is included in the zip archive.
