At 21:18 on September 13, 2022, Beijing time, my country used the Long March VII Rockets at the Wenchang Aerospace launcher to successfully launch the "Zhongxing 1E" satellite. The satellite enters the scheduled track smoothly, and the launch task has been successfully successful.

The satellite is mainly used to provide users with high -quality voice, data, radio and television transmission services.

Long March 7 changed the shipping Rockets by China Lauding Rocket Technology Research Institute (hereinafter referred to as the "Rocket Institute") of China Aerospace Technology Group Co., Ltd. (hereinafter referred to as the "Rocket Institute"). Based on the three -child of the Rockets and Long March No. 3 Language Rockets, a high -orbit three -level liquid bundled carrier rocket formed by the combined design, the landing capacity of the Earth synchronized orbit is not less than 7 tons, filling the synchronization of my country Lange Rocket Earth Synchronous The gap between the transit orbital 5.5 to 7 tons of carrier capacity can be adapted with two rectifiers: 4.2 meters and 3.7 meters. It has one arrow and one star and one arrow double main star launch ability.

According to Wei Yuanming, the chief designer of the Long -Seven Rockets, the long seven -changes and five rockets of the long seven -changes and five rockets of this task uses a rectified cover of 4.2 meters in diameter. The whole arrow height is 60.1 meters. The rocket is consistent. As the first type of binding rockets that adopt the first type of booster and core clustering technology in my country, compared to the first -level ways to separate the aid machine and then separate the core, the rocket is bundled. The link structure is more simplified. At the same time, the beam separation also reduces a helper landing area. The entire combination is in a landing area, which is more conducive to controlling the rocket wreckage landing area.

According to Wei Yuanming, as a full -temperature rocket, the long -seven -modal rocket is also the new generation of rockets with the largest number of modules in my country. It consists of 4 aids, core first -level, core two, and core three -level. In the past, they needed to be prepared for all parts, and then the vertical assembly was completed. In this task, the team changed the assembly mode from "in one go" to "to follow the hanging" to optimize the assembly time.

The task was the 437th flight of the Long March series of the Lange Rockets.
