AsteriX. Pointing software for telescopes |
Built in the years '60, this telescope is located at our stellar station at Serra La Nave (mt 1750 asl). For both axis of the telescope, the original transission system of endless screw & toothed wheel has been mechanically interfaced with two incremental encoders for a pointing with an accuracy better of 5 arcsec. The "glue" between mechanics and software is electronics. From the hardware of motors to the user's interface, the system has four levels of feedback: for the control the speed of the motors, the precision of their speed, their positioning and the position of the whole telescope.
A first level of supervision of the motors is performed by the Servo Amplifier with a Tachogenerator. The supervising control is done by a Pentium @ 600 MHz Personal Computer. There the Asterix software check the position of the telescope and ensures that the requested star is into the observing field.
Here is a block diagram of the telescope motion control system.
