                         ABSTRACT: This work considers the problem of transition between 
                         operating modes and attitude control analyzing the actuator system 
                         with sensors aid. The attitude is propagated using the dynamic 
                         movement equations. It is analyzed the effects that arise during 
                         the transition of operating modes. A control system closed loop is 
                         considered with actuators wich represent the behavior of 
                         propellers, reaction wheel and magnetic coils. It is not intended 
                         in this study to specify the causes of the faults and / or 
                         disturbances as well as specify technological details of the 
                         sensors and actuators that can be used in a real vehicle. With 
                         simulations of aid seeks to analyze the effects of these 
                         transitions between the operating modes and study cases who can 
                         provide information on various setting conditions.",
