Qiandeng 01 star and Haichuang Qiandeng were successfully put into orbit by Jailong 1.
At 12:11 on August 17, Beijing Qiandeng Exploration Technologies Co., Ltd. (hereinafter referred to as Qiandeng Exploration) developed the Qiandeng-01 satellite, which was launched at Jiuquan Satellite Launch Center aboard the Jielong-1 Yaoyan rocket of China Aerospace Science and Technology Group.
After 552 seconds of flight, JELONG-1 successfully separated from the satellite at 12:20:52 seconds, and put KJY-01 into a solar synchronous orbit at 540 km altitude.
The launch took the form of “one arrow, three stars”. In addition to the 1000 times 1 01 satellite, the Jielong 1 carrier rocket will launch the satellites of “Star Age-5” and “Tianqi-2”. All three satellites have successfully entered their scheduled orbits.
Qiandao-1 01, named “Haichuang Qiandao” by the Haidian District Government of Beijing, took 14 months to develop and weighed 65 kilograms.
It is the largest satellite independently developed by China’s private satellite enterprises so far. It is also the first operational satellite with remote sensing and earth detection functions.
The resolution of the visible light is 1.96 meters. The remote sensing and narrowband communication are integrated to realize the functions of image return and Internet of Things information transportation.
The total length of the JELONG-1 carrier rocket is 19.5 meters, the diameter of the rocket body is 1.2 meters, the take-off weight is about 23.1 tons, and the carrying capacity of the solar synchronous orbit of 500 kilometers is not less than 200 kilograms.
JELONG I is also the smallest and lightest solid rocket in China.
According to CCTV news reports, in addition to the high efficiency of delivery, Jielong 1 also has the characteristics of high cost performance, high reliability, fast performance and fast launch. Six months after signing the contract with the user, JELONG-1 can leave the factory and launch quickly within 24 hours after arriving at the launch site.
The company will launch a heavier satellite next year, and a new satellite assembly and testing center will be put into operation. At that time, the company will have the ability to develop and manufacture multiple satellites in parallel.
In the next four years, we will complete the engineering networking of 24 satellites and the construction and deployment of four sets of ground stations around the world. At that time, it will form a hourly spatial information service capability anywhere in the world and play a role in national defense, emergency response, land, agriculture and forestry and other fields.
