Two 20 -ton aerospaces in my country are connected for the first time in the Rail Communications Fair, and the Xi'an Satellite Surveying and Control Center seamlessly supports

At 14:22 on July 24, 2022, my country successfully launched the questioning of the Tianchang space launch site in Wenchang Aerospace. Words are running in orbit. As the track calculation backup center of this task, the dispatch management center of the land base and control network, the Xi'an Satellite Surveying and Control Center provides key measurement and control support for the entire task.

In the Flight Control Hall of the Xi'an Satellite Surveying and Control Center, the reporter saw that on the huge electronic screen, the curve representing the rocket flight state is changing in real time with the rocket flight.

"Lingshui, discover the goal!" "Sanya, track normal!" ... the Long March 5 of the Temple Experimental Cels, the carrier 5 of the carrier rocket, and in the measurement and control stations, the command and dispatch mouth made this up and inspiring. The remote test data of the rocket and the experimental cabin continuously brings together the flight control hall.

After the Rockets fly for about 8 minutes, the real -time screen and remote test data of the large screen show the separation of the arrows at the same time, and the position of the track calculation is immediately put into a tense calculation. Soon, the initial track and separation point parameters of the experimental cabin were calculated. The relevant data was transferred to the center of Beijing and achieved comparison to provide key data support for the successful success of the launch task.

"After the space station enters the rail construction stage, due to the changing structure in the rail structure, the flying posture mode will also be repeatedly switched, including the three -axis stable ground -oriented flying posture, inertial flying posture, orbital system positive direction Flying posture and gravity gradient stable flight posture, etc., put forward high requirements for the stability of the ground measurement and control system. "Yang Yongan, a senior engineer of the Xi'an Satellite Surveying and Control Center, told reporters that" During the task preparation process, we analyze the key technologies of the task in depth For the process, comprehensively grasp the risk factors, formulate risk response measures to ensure the controlling risk. "

At the same time, the ground measurement and control system will also be tested by the number of targets and complicated experimental transposition operations. During the construction of the space station, the Xi'an Center will organize the ground measurement and control equipment to follow the target tracking and point frequency switching in accordance with the aircraft measurement and control plan. And comprehensive use of the relay tracking of the relay and control zone in the country to achieve continuous measurement and control coverage.

In the second half of the year, my country's aerospace launch mission density will continue to maintain ultra -high density. To this end, the Xi'an Center breaks the single model led by the technical chiefs of the technical chiefs in Xi'an Center to actively implement the "dual -line" management model of the headline and the technical line. Task organizational model and deepening post fusion. Strike high -density launch measurement and control tasks high -quality and efficient development.

During the subsequent construction of the space station, the Xi'an Satellite Surveying and Control Center will continue to organize various measurement and control stations to provide stable surveying and control support for follow -up work.
