Satellite Tracker cannot track a balloon since the balloon does not have corresponding orbital elements (TLE data) since a balloon is on its own trajectory steered by wind currents, drag, etc.. In order to track a balloon one must have a tracking system setup to track an object via object detection via video and a tracking algorithm based on alpha-beta, kalman filtering, or other methods. These methods detect an object's video footprint, determine speed and direction during the acquisition phase, then "track predictions" and "tracking" during the tracking phase with the capability to coast the tracking algorithm should video be temporarily lost or corrupted. During these phases the telescope motion is adjusted to keep the video footprint in the center of the field of view.
I hope this helps.
