synonymXi'an Satellite Measurement and Control Center(Xi'an Satellite TT&C Center) generally refers to China Xi'an Satellite TT&C Center
China Xi'an Satellite TT&C Center was built in 1967. It is located in the temperate zone, with convenient transportation, and is located in the hinterland of China.It has the capability of multi orbit, multi spacecraft, remote tracking and precise measurement and control.The TT&C center relies on the TT&C network that tracks and measures the flight state of spacecraft and controls its movement and working state to track, measure, monitor and control spacecraft, so as to measure and control the movement of spacecraft.

At 23:08 on November 29, 2022, China successfully launched the Shenzhou 15 manned spacecraft at Jiuquan Satellite Launch Center.Xi'an Satellite Measurement and Control Center successfully completed the launch and measurement and control mission of Shenzhou 15 manned spacecraft.[3]
In May 2023, China successfully launched the 56th satellite of Beidou Satellite Navigation System at Xichang Satellite Launch Center.After the satellite was successfully put into orbit, it has been taken over by Xi'an Satellite Measurement and Control Center, and the early orbital segment measurement and control work is being carried out. On the 25th, this new Beidou satellite will officially enter the "big family" of Beidou constellation.[4]
On June 4, 2023, the return capsule of Shenzhou 15 manned spacecraft successfully landed at Dongfeng landing site, and Xi'an Satellite TT&C Center and various TT&C stations successfully implemented the TT&C mission of the return phase of the spacecraft.[5]
At 10:32 on June 10, 2024 (Beijing time), China's first all electric push communication satellite, the Asia Pacific 6E, was successfully positioned at the 135.5 ° east longitude orbital position (test orbital position) under the tracking control of Xi'an Satellite Measurement and Control Center.[6]
