The Heliomaster is a small control box which is mounted on (or parallel to) the heliostat surface.

Heliomaster Features

1. Autonomous:
1.  accurate control without central controller (~ 1mrad)
2.  approximate track in case of sun occlusion
2. Optically Closed loop:
1. Simple Optical arrangement (patent pending) allows measurement of the position error
2. Output motion commands based on position error
3. Zero calibration work
4. Directly drives stepper motors
5. Communication and position control for non tracking operation:
6. Simple mounting
