CL_man_apsidesLine

Delta V required to change the line of apsides

Calling Sequence

[dv,anv] = CL_man_apsidesLine(ai,ei,pomi,pomf [,posman,mu])

Description

Parameters

ai :

Initial semi major axis [m] (1xN)

ei:

Initial eccentricity (1xN)

pomi:

Initial argument of periapsis [rad] (1xN)

pomi:

Final argument of periapsis [rad] (1xN)

posman:

(optional) Flag specifying the maneuver location (0->close to periapsis, 1->close to 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)
