Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com news on November 14, according to Beijing Aerospace Control Star Technology Co., Ltd. (hereinafter referred to as "Aerospace Control Star"), 06:02 on November 14, 2022, Zhixing III An ejected from the Tianzhou IV cargo spacecraft, and the satellite entered the scheduled orbit smoothly. The space control satellite provides the satellite with in-orbit test after the separation of the star ship and the measurement, control and data transmission services in the long-term management phase of the satellite.

According to reports, this is the space control star to provide measurement and control services for the first commercial satellite in China to take a cargo spacecraft into orbit. The orbit height of Zhixing 3A is low, and the measurement and control arc of each orbit is short, which puts forward higher requirements for the orbit determination and prediction ability of the measurement and control team. Relying on the advantages of rich ground station resources at home and abroad, the space control satellite adopts the mode of multi-station continuous relay, which effectively ensures the measurement and control time of the key arc section of the separation of the star ship and the reliability of the satellite measurement and control after the separation. In the first lap of the separation of the starship, the space steering star deployed a total of 10 sets of equipment in five places, including Azerbaijan, providing a tracking time of more than 20 minutes, successfully ensuring the satellite's entry into orbit.

Zhixing 3A, developed by Zhixing Space, was launched in Wenchang on May 10 on a Tianzhou cargo ship. Following the cooperation between the missions of Zhixing-1A and Zhi-Xing-3A, the space pilot will continue to provide measurement and control services for Zhixing-2A. Up to now, the space steering star has been paid to serve 174 stars per arrow.

CTOnews.com has learned that the micro vehicle on-orbit release mechanism equipped by the Chinese space station can meet the on-orbit release needs of 100-kilogram micro-vehicles or multiple local stars, and solve the problem of low-cost entry of micro-satellites and local stars into space.

Experts say the first part of the process of launching a satellite in orbit is similar to loading out of the cabin, grasping the micro-satellite release mechanism through a robotic arm and ejecting directly using a spring mechanism in the direction you want to release. In this way, tiny satellites can be sent on the space station without occupying a rocket, and the satellite can be put into orbit quickly, economically and efficiently.

In addition, Tianzhou-4 will be controlled to re-enter the atmosphere on November 15, 2022, Beijing time, most of the spacecraft's devices will be ablated and destroyed during re-entry, and a small amount of debris will fall into the scheduled safe waters of the South Pacific.
