China successfully launched its first low orbit broadband communication technology verification satellite, the first Hongyun project satellite of China Aerospace Science and Technology Group Co., Ltd., into a predetermined orbit with the Long March 11 carrier rocket at Jiuquan Satellite Launch Center on the morning of Tuesday. Hongyun project first star successfully launched! Build China's space-based Internet.
China Academy of Launch Vehicle Technology said that since its successful first flight in September 2015 in the form of "one rocket, four stars", the Long March 11 launch vehicle has achieved five consecutive successful launch missions, reflecting the high performance and high reliability of the solid launch vehicle. At the same time, the implementation period of this launch mission is only half a year, and the market response capacity of the Long March 11 rocket is greatly enhanced.
This is the first time that the Long March 11 rocket has carried out a launch mission of more than 1000 kilometers of sun synchronous orbit, which brings some difficulties to the orbit optimization and energy control of the rocket. Therefore, the research team has made adaptive improvements in the orbit design, guidance design and flight control software. Jin Xin, deputy commander in chief of the Long March 11 rocket, pointed out that "the successful mission means that the rocket's mission adaptability has been further enhanced.".
Jinxin believes that the construction of China's LEO satellite constellation communication system will have the scale of about 800 satellites, and the launch market is promising. Most of the launch orbits are concentrated at about 1000 kilometers. The successful launch of the Long March 11 rocket will lay a good foundation for the follow-up participation in constellation system networking and supplementary network launch.
According to the rocket expert, the Long March 11 rocket is going all out to carry out various preparations for the sea launch, and it is planned to launch China's first carrier rocket at sea in June 2019. At the same time, the research and development team is also demonstrating that the long march 11-A Solid Launch Vehicle with a low orbit carrying capacity of two tons has a larger carrying capacity and higher cost performance.
The China Academy of launch vehicle technology also concluded that the Long March 11 launch vehicle has created 11 China's first: the first type of Solid Launch Vehicle approved by the state, the first type of launch vehicle to achieve hourly launch, the first type of launch vehicle with mobile launch capability, the first type of launch vehicle with long-term storage capability, the first type of launch vehicle that can be launched without support The first type of launch vehicle is suitable for complex launch environment, the first type of Solid Launch Vehicle with practical launch capacity, the first type of launch vehicle suitable for rapid launch of small satellites, the first type of four-stage all solid launch vehicle, the first type of solid launch vehicle providing carrying service to foreign satellites and the largest solid launch vehicle in China at present.
