A long focal length dynamic aim generator is applied to simulate the image motion and the variety drift angle  and to detect the precision of the image motion compensation machinery and the capability of the drift angle control system. The computer system is used to control the dynamic aim generator  accomplish the data processing  transmit and receive the data information. The seamless connection and the data transmission between the aim generator and the aircraft simulation devices are constituted. The command  parameter and drift angle data transmitted by the simulation devices are received by the space camera at the real time  then the photos are taken and the draft angle is adjusted simultaneously. It is shown that the drift angle can be accurately tracked by the space camera at the real time  and the detective method satisfies the test requirement. 2010 Copyright SPIE - The International Society for Optical Engineering.
