After starting the rocket should be developed in the so-called guidance plane. At Baikonur launch pad rotates, because in the 50's analogue systems are not able to so active spinning. On a more modern launch sites in Kourou on the "East" there is no need to do this, the rocket itself rotates. Depending on the position of the launch pad and launch trajectory angle of rotation may be different, according to the video to start at a very similar sun-synchronous orbit with an inclination of 98 ° to Kourou it turns out approximately 90 °, to the "East" in the region of 180 °
