A measurement arrangement is useful for controlling the attitude of a three-axis stabilized satellite equipped with sun-sensors for determining the orientation of the sun (sun vector) with respect to a satellite-fixed coordinate system, as well as with speed gyroscopes for detecting components of the satellite speed of rotation vector wa2max on both sides of the plane. In addition, only an integrating speed gyroscope carrying out measurements in a single measurement axis that encloses with the plane an angle of at least (pa2max should be provided. Also disclosed are an evaluation process for determining the satellite speed of rotation, as well as the satellite deviation with respect to a direction of reference, a regulating system for carrying out attitude control maneuvers using the measurement arrangement and the evaluation process, and a corresponding regulating process.
