<p><big> Transformation into STADAN </big></p>
<p>As satellites grew bigger and more sophisticated, there were a number of problems that Minitrack could not handle well, and some capabilities that were not needed. These included:<br/>
* Satellites in polar orbits. This required new sites to track.<br/>
* Satellites in synchronous orbits. These have bearings that change slowly (or can be completely stationary). This makes angle tracking much less useful. What is needed in this case, especially for maneuvers of such satellites, is range and range rate. Minitrack</p><p>
