Yesterday (June 3), the Shenzhou 14 manned flight mission completed a comprehensive exercise in the whole navigation area before launch. The mission's TT & C stations implemented joint commissioning and control to ensure that all systems were ready to perform the launch mission before launch** The whole navigation area comprehensive exercise is a comprehensive exercise covering the whole process, all elements and the whole system of the Shenzhou 14 mission area. The whole navigation area joint exercise is a comprehensive simulation exercise with the most and the most complete measurement, control and communication systems in addition to the ignition and launch. It is also the last exercise before the launch. The joint commissioning and joint test work has been completed between the Beijing aerospace flight control center, the measurement and control stations, the Yuanwang 3 measuring ship and other systems, All systems in the region have the conditions for launching missions.
Lijinguang, dispatcher of "Huashan" of Xi'an Satellite TT & C Center: in view of the new situation and characteristics of Shenzhou 14 mission, we improved the central computer system and optimized the orbit calculation mode to ensure the accuracy and reliability of various calculation data at all stages of the mission.
CCTV reporter he Chun: after the last drill before launch, the filling system pipeline and equipment connection, the whole system air tightness inspection, propellant temperature regulation and other work will be carried out here to prepare for the follow-up filling tasks.
Since the Shenzhou 14 rocket assembly was transferred to the launch area on May 29, the launch site system has completed the launch drill of rocket, spacecraft, launch site, measurement and control, communication and other systems, simulated the launch process of all personnel, whole process and all elements, and comprehensively inspected the stability of the test equipment and the coordination ability between the major systems.
Qintong, chief designer of the long march 2F carrier rocket of the first Academy of Aerospace Science and Technology Group: according to the test results of the current system wide launch drill, the product quality of the long march 2F Yao 14 carrier rocket is qualified, and all functional performance indicators meet the task requirements.
Dengxiaojun, commander of Shenzhou 14 manned mission 0: through the drill, the matching of our system interfaces, the correctness of our workflow, and the completeness of our support work have been tested. The performance of the spacecraft and rocket products is also very good. The astronauts' work is also very smooth, so they have the conditions for the rocket to enter the key stage of refueling and launching.
