TargetSlew:

Path: SCPro/ProTools

% Compute a slew to a target.
   Computes the angle, angular rate and angular acceleration for a spacecraft
   in a circular orbit that is pointing at a target on the ground. If inertia
   is not entered units are rad/sec^2 and rad/sec otherwise they are Nm and
   Nms
--------------------------------------------------------------------------
   Form:
   varargout = TargetSlew( altitude, rTarget, mu, inertia )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   altitude       (1,:)  Apogee radius
   rTarget        (1,1)  Target radius from center (defaullt 6378)
   mu             (1,1)  Planet gravitational parameter (default Earth)
   inertia        (1,1)  Inertia (kg-m^2) (default is 1)

   -------
   Outputs
   -------
   if length(altitude) == 1
     psiDot         (1,:)  Spacecraft angular rate
     psiDDot        (1,:)  Spacecraft angular acceleration
     psi            (1,:)  Spacecraft angle
   else
     psiDDotMax     (1,:)  Required maximum torque
     momentum       (1,:)  Required momentum storage
