【正确答案】 D

【答案解析】[解析] 本题考查细节。由第一段第六句话，“The purpose of the inertial platform is to allow the vehicle to move in any direction about the inner gimbal(万向接头)containing the gyros and accelerometers，without disturbing or turning them from their original orientation．”可知这种制导系统的工作台的目的就是防止系统改变原来的方向。所以选项[D]正确。
