This is my first launch vehicle on which an automatic orbital entry program is installed, to launch it you need to activate AG 2 and do not touch anything else, the launch vehicle itself will enter an orbit of 200 km, the permissible error is 20 km (depending on the quality of physics)

Soyuz-2.1a is a Russian medium-class launch vehicle (LV), designed for launching various spacecraft, including ships and military satellites. It is the first modification of the Soyuz-2 family of space rockets, developed through a deep modernization of the Soyuz-U launch vehicle, for various types of head units with nose fairing diameters of up to 4.11 m. This launch vehicle is characterized by increased launch accuracy and increased payload mass in low orbits due to improved control systems and propulsion systems of stages I and II.
