In Baikonur, the ship was a special room covered with radio absorbent materials, and successfully passed the control in the Amych cell. Such a camera simulates full insulation conditions from external radio signals and allows you to test the operation of radio equipment on top of each other without parasites.
Particular attention was paid to the “Cource” system, which is responsible for the zoom and participation of the ship with ISS. The tests showed the correct operation of the equipment that criticizes the successful connection of the crew to the orbit safely and criticizes the successful connection with the station module.
Such controls are a standard procedure for the preparation of manned flights and make sure that all ship systems work reliably in space conditions.
