CL_op_rpvinf2ae

Description

• Computes semi major axis and eccentricity from periapsis radius and velocity at infinity (hyperbolic orbits only).

  Nota: The velocity at infinity vinf must be greater than zero

Parameters

rp:

Periapsis radius [m] (1xN or 1x1)

vinf:

Velocity at infinity [m/s] (1xN or 1x1)

mu :

(optional) Gravitational constant [m^3/s^2] (default value is %CL_mu)

sma:

Semi major axis [m] (1xN)

ecc:

Eccentricity (1xN)
