The TOAST is based on a P8600 CCD detector with microprocessor control and starimage processing. Three modes of operation are provided. The camera mode permits visual interpretation of the starfield. In acquisition mode stars are searched for in regions specified by the on-board computer. In tracking mode the ultimate accuracy is obtained for a maximum of three stars. A functionally representative model was built, software implementation is in a final stage.
