Solution Approach 1:

The patent replaces mechanical tracking systems with an image recognition-based method that continuously photographs and identifies stars. This software-based approach eliminates mechanical failure points, providing more reliable tracking through algorithmic coordinate calculation rather than mechanical motion control.

Inventive Principle:
