The Zhixing-3A satellite was ejected from the Tianzhou-4 cargo spacecraft of the China space station

According to Beijing Aerospace Yuxing Technology Co.Ltd. (hereinafter referred to as "Space Yuxing"), at 06:02 on November 14, 2022, Zhixing 3A star from Tianzhou 4 The cargo spacecraft was ejected, and the satellite successfully entered the predetermined orbit. Aerospace Yuxing provides satellites with on-orbit testing after the separation of the star vessel, and measurement and control and data transmission services in the long-term management phase of the satellite.

This is the first time that Aerostar provides measurement and control services for a domestic commercial satellite that has entered orbit on a cargo spacecraft. Zhixing-3A has a relatively low orbital altitude, and the measurement and control arc of each orbit is relatively short, which puts forward higher requirements on the orbit determination and forecasting capabilities of the measurement and control team.

Relying on the advantages of rich ground station resources distributed at home and abroad, Aerospace Yuxing adopts the multi-site continuous relay mode, which effectively guarantees the measurement and control duration of the key arc section of starship separation and the reliability of satellite measurement and control after separation. In the first round of starship separation, Aerospace Yuxing deployed a total of 10 sets of equipment in 5 places including Azerbaijan, provided more than 20 minutes of tracking time, and successfully guaranteed the satellite into orbit.

Zhixing-3A was developed by Zhixing Space and was launched in Wenchang on May 10 on a Tianzhou cargo spacecraft. Following the cooperation of Zhixing-1A and Zhixing-3A missions, Aerostar will continue to provide measurement and control services for Zhixing-2A. Up to now, Aerospace Yuxing has accumulatively provided 174 stars/arrows for paid services.

Micro-aircraft on-orbit release mechanism configured by China's space station can meet the on-orbit release needs of 100-kilogram micro-aircraft or local satellites of multiple specifications, and solve the problem of low-cost entry of micro-satellites and local satellites into space.

The first part of the process of launching a satellite into orbit is similar to the load out of the cabin. The mechanical arm grabs the release mechanism of the tiny satellite, faces the direction you want to release it, and uses the spring mechanism to eject it directly. In this way, micro-satellites can be launched on the space station without occupying another rocket, and the satellites can be quickly put into orbit, which is economical and efficient.

Tianzhou-4 will re-enter the atmosphere under control on November 15, 2022, Beijing time as planned. Most of the spacecraft’s components will be ablated and destroyed during the re-entry process, and a small amount of debris will fall into the predetermined safe sea area of ​​the South Pacific.
