At 9:43 on June 23, 2020, China launched the last satellite in the third-generation network of China's Beidou Navigation Satellite System from the Xichang Satellite Launch Center. The 55th satellite in the Beidou Navigation Satellite System was sent into space by a Long March 3B carrier rocket. After a period of in-orbit tests, the new satellite will start formal operations and work with other Beidou satellites to enable users around the world to obtain all-time, all-weather and high-accuracy navigation, positioning and timing services. Its lunch marked the completion of the in-orbit construction of the BeiDou Navigation Satellite System and the successful conclusion of the "three-step" strategic task of Beidou satellite navigation system. It is also the first major national project to be completed in the aerospace field during the 13th Five-Year Plan.

ZYS, as the only state-level comprehensive research institute in China's bearing industry, has completed high-quality supporting work for momentum wheel bearings and rocket engine bearings once again, helping the Beidou to travel into space and serve the whole world. The bearing is the core component of the momentum wheel bearing assembly, and the momentum wheel is the core attitude control component of the satellite. If something goes wrong with the bearing assembly, the satellite will lose its balance in orbit and its navigation function. Therefore, the performance, life, and reliability of bearing components are critical to satellites. ZYS products provided solid guarantee for the long-term stable and reliable operation of the Beidou navigation satellite System.

ZYS, as a leading scientific and technological enterprise in China's bearing industry and a major supporting unit of China's aerospace industry, will remain true to our original aspiration and keep our mission firmly in mind, and make contributions to the realization of a bigger space dream and Chinese dream.
