Subsystem -2 (Electronic Subsystem) - Telescope over the Internet

The telescope is controlled by two motor controllers and a main controller to drive the two stepper motors attached to the telescope. The two motor controllers are attached to the main controller and the main controller is connected with the dedicated server through RS232.

The motor movement commands carrying degrees by which the two motors have to be turned from the current location are sent from the server through the RS232 protocol to the main controller. The main controller board calculates the steps for each motor and sends the appropriate motor commands to both individual motors.

The two motors are driven sequentially. The time taken to turn is also calculated and compensated while delivering the degrees by which the telescope needs to be turned and this will be explained in detail in subsystem 3
