SpaceStationDragDisturbance:

Path: Missions/SpaceStation

% Calculates drag for the LEO space station
 This drag model uses the scale height atmosphere and a custom data
 structure of surface data.

 Type SpaceStationDragDisturbance for a demo. The demo requires you to
 first run ManufacturingSpaceStationCAD to produce SpaceStationProps.mat.

 This can be called in batch mode with arrays of time and state. Call
 without outputs to produce a plot.

   Form:
   SpaceStationDragDisturbance;  % demo
   SpaceStationDragDisturbance(r,v,q,t,d);  % create plots in batch mode
   [torque,force] = SpaceStationDragDisturbance(r,v,q,t,d) % output mode
