CL_man_sma

Delta V required to change the semi-major axis

Calling Sequence

[dv,anv] = CL_man_sma(ai,ei,af [,posman,mu])

Description

Parameters

ai :

Initial semi major axis [m] (1xN)

ei:

Initial eccentricity (1xN)

af :

Final semi major axis [m] (1xN)

posman:

(optional) flag specifying the position of maneuver (0->periapsis, 1->apoapsis; default is 0) (1xN)

mu :

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

dv :

Delta_v in spherical coordinates in the QSW frame [lambda;phi;|dv|] [rad,rad,m/s] (3xN)

anv:

True anomaly at the position of maneuver [rad] (1xN)
