Xi'an Satellite TT & C Center creates the shortest Space TT & C Mission interval record in China
Xinhua News Agency, Xi'an, 15 Nov (Li Guoli and Lu Binghong) within 175 minutes, two rockets with a number of satellites were ignited from the two launch sites one after another. As the main measurement and control unit, Xi'an Satellite TT & C Center has successfully completed the multi-point parallel TT & C task and set the record of the shortest space launch TT & C mission interval in China.
"Menghai, tracking is normal!" "Qingdao, find the target!" On November 13, in the two command halls not far away from the Xi'an Satellite Measurement and Control Center, dispatching passwords from various measurement and control stations one after another. In the course of the mission, under the unified dispatching command of the center, the measurement and control stations have successively completed the tracking and measurement of the two carrier rockets, the data acquisition is complete and effective, the information processing and transmission is correct, and the operation of software and hardware is stable. The communication message link is unblocked. Finally, all satellites accurately enter the intended orbit and establish a normal working state.
At present, there are four space launch sites in China: Jiuquan, Xichang, Taiyuan and Hainan. It is understood that since the launch of the rocket, all spacecraft launched from the four space launch sites have been carried out by the Xi'an Satellite Measurement and Control Center for a series of operational controls, such as tracking and measurement, state monitoring, attitude adjustment, orbit control, and so on. Finally, the spacecraft can accurately enter the predetermined orbit and put into operational application.
In view of the normalization of high-density tasks in recent years, this center independently develops and perfects an efficient, reliable and functional multi-satellite measurement and control software system. The support of multi-satellite data fusion processing, constellation management, sky-ground joint measurement and control and inter-satellite link is realized, and the comprehensive measurement and control ability is greatly improved. In addition, they also actively optimize the task software, build a modular framework, reduce the task preparation time from two months to half a month, and effectively improve the ability of multi-task parallel measurement and control.
Yu Peijun, director of the center, said that at present, they are able to support the parallel launch and measurement and control of multiple spacecraft at all space launch sites in China. "in order to meet the needs of the rapid development of China's space industry, the center will continue to improve its measurement and control capability and complete subsequent launch measurement and control tasks with a 100% success rate," he said.
