% 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
