The trackers are controlled by the SunGravityControl robotic system that measures the vector of gravity, calculates the position of the tracking surface by comparing the angles of orientation with gravity, and power the motors to move the trackers towards the Sun.
The position of the sun is calculated using an internal clock. The inclinometer is installed using pick-and-place techniques that are extremely precise.
The SunGravityControl robotics developed by WS Energia has an USB-on-the-go interface which allows the user to upgrade the firmware on the tracker by simply connecting a USB pen.
