A test system for dynamical images of Time Delay and Integration Charge Coupled Device(TDICCD) cameras in space was designed to simulate the ground image motion related to the space aerocraft and to validate the capability of image speed matching and the quality of dynamical imaging of TDICCD cameras. The design adopted a precision table and a drift table to simulate the aerocraft motion around the earth and its drift motion in different latitudes caused by the earth rotation. The precision table drived by a permanent magnet torgue motor was controlled by a phase locked loop serve-control strategy and its steady speed error reaches 0.029 7%. The drift table was drived by a stepping motor and its average rotation speed is 0.02 (°)/s and trace precision of draft angle is better than ±5′. The experimental results show that the precision of designed system meets the test requirement for the dynamical images of TDICCD cameras,and has been applied to the development of a certain space visible light camera.
