mubody.core.kepler.Bm

mubody.core.kepler.Bm(rper, Vinf, mu)

Module of B-point vector.

Calculated from the Vinf of the incoming trajectory and the periapsis radius of the target orbit.

Parameters:

• rper (float) – Perigee radius [km]

• Vinf (float) – Hyperbolic excess of velocity [km/s]

• mu (float) – Standard gravitational parameter [km3/s2]

Returns:

Bmod – Module of the B-point vector [km]

Return type:

float
