The paper presents the results of an experiment on simultaneous attitude determination for the system of the three star trackers in inertial coordinate system by observing the stars both in the normal mode and single frame shooting mode. The accuracy of determining the angle between instruments’ Z axes is estimeted. The dependence of the accuracy of determining the rotation angle around the Z axis and the angle between the instruments’ axes is derived.
