China's space-based TT&C system successfully completed the TT&C tasks of the launch, orbit entry and rendezvous and docking section of Tianzhou-2, and successfully entered into the space-based TT&C task state of the operation section of the Tianzhou-2 core module and the Tianzhou-2 combination.
This is the first time that China's space-based TT&C system has performed a TT&C mission aboard the space station complex.
China's Tianzhou-2 cargo spacecraft lifted off from the Wenchang Space Launch Center in Hainan on May 29, and completed automatic rendezvous and docking with the Tianzhou-2 core module in the early morning of May 30.
"Space-based tt&c cover large segment, track time, the characteristics of high transmission rate, especially in the manned space mission, the relay satellite system can drastically to exert their own advantages, to say, the day chain satellite captured the moment day boat no. 2, day boat no. 2 running most of the segment will be in our monitoring.""Said Ma Chao, head of the mission.
As the main measurement and control method of the two spacecraft rendezvous and docking, the Beijing Space Information Transmission Center provided real-time data support to the Beijing Aerospace Control Center in the rendezvous and docking section. During the period, all sub-systems cooperated closely and the data and information received and received were normal, which enhanced the stability and reliability of the rendezvous and docking implementation.
At present, the central staff is being kept on duty 24 hours a day to carry out the long-term space-based TT&C mission of the space station complex as planned.
