Direct Ascent Trajectory

Direct Ascent

In Direct Ascent the trajectory selected such that destination point lies in the required orbit,  the satellite which in most cases is attached to the final rocket stage, approaches this destination altitude , the final stage stage motor is ignited and the satellite is accelerated to the required orbital velocity.In some cases the rocket motor required for this acceleration is not the motor of last stage, but is an integral part of satellite itself.
