CL_cw_propagateMan

Description

• Propagates using clohessy-Whiltshire equations (including a constant relative acceleration and possible impulsive maneuvers).

  The reference frame used is the target's LVLH local frame (origin = target).

  The reference altitude alt is the altitude of the target = semi major axis of target's (circular) orbit minus equatorial radius.

  acc is a (constant) differential inertial acceleration with components in the reference frame.

  tman and dvman are optional maneuvers performed by the "chaser" (components in reference frame).

Parameters

t0:

Initial time [days] (1x1)

pv0:

Initial (relative) position and velocity vectors in reference frame [m,m/s] (6x1)

t:

Final (increasing) times [days] (1xN)

alt:

Reference altitude (= altitude of target) [m] (1x1)

acc:

(optional) Differential (constant) acceleration in reference frame (m/s^2). Default is []. (3x1)

tman:

(optional) times of maneuvers. Must be sorted increasingly [days]. Default is []. (1xP)

dvman:

(optional) Velocity increments [m/s]. Default is []. (3xP)

er:

(optional) Equatorial radius [m]. Default is %CL_eqRad

mu:

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

pv:

Relative position and velocity vectors at time t in reference frame [m,m/s] (6xN)
