The testing micro spacecraft detects the Space exploration technology. By studying the trajectory and attitude change, the real-time response and accuracy is compared and analyzed. Disturbance of launching process changes initial operation conditions. The orbital dynamic model and attitude dynamic model considered environmental factors based on Euler equation are developed, and a numerical calculation about operation process is carried out under different initial operation conditions. The results indicate that: various degree of change about the motion situation for spacecraft is taken place when initial operation conditions change; orbital eccentricity and period increases with the increase of initial orbit entry velocity; nonzero launching angle will cause orbit displacement and rotation, pitch launching angle mainly cause the variation of pitch angle, Yaw launching angle mainly effects roll angle and yaw angle, and greater the angle, the greater the range; the attitude changes reduce when the spin angular velocity increases.
