China News Service, Beijing, October 27th (Guo Chaokai) At 23:19 on October 26th, Beijing time, China used the Long March 2C carrier rocket at the Xichang Satellite Launch Center to successfully integrate remote sensing three satellites with one arrow and four stars. The three satellites of the 10th group 07 and the 06 star of the Apocalypse constellation were sent into the predetermined orbit, and the launch was a complete success.

Remote Sensing No. 30 and Group 07 satellites adopt a multi-satellite networking mode, which is mainly used to carry out electromagnetic environment detection and related technical tests.
Apocalypse Constellation 06 is a short message communication satellite developed by Beijing Guodian Hi-Tech Technology Co., Ltd., and is the sixth satellite of the Apocalypse data acquisition constellation, which can provide DCS data transmission services for ground users.
The Long March II C rocket for this launch mission was developed by the China Academy of Launch Vehicle Technology affiliated to China Aerospace Science and Technology Corporation.
This type of rocket is a conventional liquid carrier rocket. It flew for the first time in 1982 and has undergone many improvements. It is currently the longest-serving carrier rocket in China, and is the first to win the title of "Gold Medal Rocket" with its high success.
The Long March II C rocket is also one of the reliable platforms for China to verify new technologies in the field of space transportation.
On July 26, 2019, the Long March II C rocket carried out a fairing/parachute and a sub-level/grid rudder separation area safety control technology test at the same time during a launch, making China the second successful verification in the world Countries with this technology have laid the foundation for the subsequent development of launch vehicle landing control and even reusability.
In this mission, the Long March 2 C rocket fairing was again equipped with the landing zone safety control system, and its main electronic equipment was recovered from the fairing landing zone safety control system during the flight test on July 26, 2019. This is China Aerospace For the first time in the history of transportation, sophisticated electronic equipment was reused at the "system level".
In addition, China's "smart rocket" related technology also uses the landing safety control system to conduct the first flight verification during the complex reentry process of the fairing.
The current main goal of the "smart rocket" technology is to intelligently re-plan the flight path in time according to the rocket's state after a major failure in the rocket flight, so as to save the mission as much as possible.
In the future, the application of this technology will further increase the launch success rate.
This mission is the 350th flight of the Long March series of carrier rockets.
