ECE 477 Team 18 - Timothy Brown Humble Hubble ECE 477 Team 18 - Timothy Brown Abstract The proposed project is a self-aiming telescope. This telescope will obtain its global position and the local time via GPS. It will then automatically orient itself to point at a user selected target (star) using a variety of onboard sensors.
