The existing fine attitude system of the Astronomical Netherlands Satellite was designed on the basis of conventional digital control techniques. The possibility of a more advanced approach is presented. As an example, an alternative control algorithm for the scan mode was developed with the use of state estimation and state variable feedback techniques. The results of computer simulations and in-orbit tests are presented. The in-orbit test results show a marked performance improvement in terms of reduced settling time after slew and reduced sensitivity to disturbance torques. Computer simulations indicate a potential for further performance improvements.
