The satellite successfully entered the predetermined orbit and the launch mission was a complete success. The satellite mainly provides reliable, stable and safe radio and television transmission and communication services for users within China's territory and territorial waters and users in the Asia Pacific region < p > this mission is the 415th flight of the long march series launch vehicle < p > < / P > < p > Photography: Xie Qiyong < / P > < p > related reading: < / P > < p > Zhongxing 6D satellite launched! On April 15, Zhongxing 6D satellite was successfully launched from Xichang Satellite Launch Center by using the long march 3B enhanced carrier rocket, and the satellite entered the predetermined orbit as planned < p > Zhongxing 6D satellite is a new generation of geosynchronous orbit communication satellite. It adopts the domestic independently developed dongfanghong-4 enhanced satellite platform to provide commercial services of C-band and Ku band transponders. After in orbit testing, it is delivered to China Satcom Group Co., Ltd. affiliated to Aerospace Science and Technology Group for operation and management, so as to provide high-quality radio, television and communication transmission services for the general public and all walks of life < p > the picture shows before the launch of the rocket. The first Academy of Aerospace Science and Technology Group provides < / P > < p > as an important national space infrastructure, Zhongxing 6D satellite can cover the whole territory of China and the Asia Pacific region, and the coverage performance of C-band repeater is significantly enhanced. It will further expand the viewing range of users and improve the viewing quality. After it is put into operation, it will undertake the transmission task of important central and local radio and television programs, which can meet the demand of 4K and other high-definition video transmission, It is the core guarantee force for the safe transmission of satellite radio and television programs in China < p > at the same time, the Ku band repeater configured by Zhongxing 6D satellite can fully meet the business needs of emerging applications such as growing consumer bandwidth, enterprise private network, base station return and ocean, and better provide diversified services for the majority of users < p > according to Zhang Yipu, chief designer of the 3A series rockets of the first Institute of Aerospace Science and technology group, the long march 3B carrier rocket that successfully put the Zhongxing 6D satellite into the predetermined orbit has been technically optimized in three aspects, improving the production efficiency and reliability of the rocket < p > reporter: Hu Zhe, Song Chen < / P > < p > editor: Li Xiaohu < / P > < p >
