Name
CL_cw_circularDrift — Clohessy-Wiltshire circular drift
Calling Sequence
[xp]=CL_cw_circularDrift(alt,z0[,er])
Description
-
Computes the relative drift on a circular orbit. Chaser on a circular orbit, coplanar with
the target orbit. Reference frame used described in CL_cw_twoImpulse.

-
Relative motion is constant velocity (dX0/dt) motion .

- z0:
chaser relative altitude [m] (1xN)
- er:
(optional) equatorial radius [m] (default is %CL_eqRad)
- xp:
drift velocity [m/s]
