StellarAttDetEKFNoGyros:

Path: SpacecraftEstimation/StellarAttDet

% A stellar attitude determination system that does not use gyros.

   w            (3,1)     Body rate
   dT                     Time step
   p            (6,6)     State covariance matrix
   Q            (6,6)     State noise covariance
   r                      Measurement noise
   qBToS        (4,1)     Quaternion from body to sensor axes
   starDataMeas
   starData     (m,3)     Vector of [intensity,xloc,yloc]
   fScale       (1,1)     Sensor scale factor

   -------
