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 .
