At 7:44 and 11:06 on February 27, my country used the Long March 4C rocket and the Long March 8 rocket to successfully launch the L-SAR01 group B satellite and the Taijing 301 satellite and other 22 commercial satellites. As the main unit of the measurement and control system, Xi’an Satellite Measurement and Control Center successfully completed the multi-point parallel measurement and control task.
The launch mission of the Long March 8 Yao-2 carrier rocket with one arrow and 22 satellites has created a new record for the launch of multiple satellites by one arrow in China’s aerospace industry, and this has put forward extremely high requirements for the performance of the rocket and the accuracy of measurement and control. “For this mission, the number of launch targets, the number of satellites and rockets to be separated, and the separation time span have all reached new highs. We conducted in-depth research on the separation process and separation mechanism of satellites, and conducted multiple rounds of discussions and exchanges with the development unit. , formed a complete separation judgment emergency response plan.” Senior engineer Zhang Jianhai introduced.
At the same time, in order to further compress the initial orbit calculation time of these 22 satellites, the test participants optimized the post interaction process of telemetry data judgment, improved the function of the arrow remote data extraction and analysis software, and at the same time carried out the telemetry parameters related to the separation of the satellite and the arrow on the special page in real time. It shows that the efficiency of initial orbit determination is greatly improved. “Combining the characteristics of the mission, we have carried out in-depth and sufficient joint debugging and testing and verification of the relevant mission software of the new research, and have formulated a number of plans for the risks of flight anomalies and data anomalies in the initial orbit determination, laying a solid foundation for the rapid determination of the initial orbit. A solid foundation.” Senior engineer Ye Xiusong told reporters.
“This year, my country’s space launch will still maintain ultra-high density, and it has become the norm to prepare for several measurement and control tasks. We will implement the ‘three major projects’ of scientific and technological innovation, talent training, and quality improvement, and continue to break through key technologies. The ‘China Star’ creates a smooth road to the sky.” The person in charge of the center told reporters.
