At 13:30 on January 11, 2024, China's Taiyuan Satellite Launch Center used the Gravity-1 (Yao-1) Heilanjia carrier rocket in the waters near Haiyang, Shandong Province, to successfully launch a total of three satellites from 18 to 20 satellites of Yunyao-1 into the scheduled orbit, and the flight test mission was successful.
The mission was the first flight of the Gravity-1 commercial launch vehicle. The launch was characterized by a sea launch.
According to reports, the Gravity-1 launch vehicle was independently developed by Oriental Space Technology (Shandong), creating a number of records such as the world's largest solid launch vehicle, China's largest civilian and commercial launch vehicle, and China's first ** civilian and commercial launch vehicle, marking the progress of China's independent innovation of commercial launch vehicles, expanding the diversification and large-scale launch capabilities of China's medium and low orbit satellites, and further enriching the spectrum of China's launch vehicles.
Gravity-1 has the characteristics of large carrying capacity, large load space, universal use on land and sea, fast response and good economy. The rocket adopts a semi-solid configuration, with a height of about 30 meters, and the diameter of the core stage and booster is 265 meters, take-off weight 405 tons, take-off thrust 600 tons, fairing diameter 42 meters, low earth orbit carrying capacity 65 tons, 500 km sun-synchronous orbit carrying capacity 42 tons, it can support the launch of 100-kilogram satellites "one arrow and 30 satellites", meeting the needs of batch launch of medium and low orbit satellite networking and rapid response launch of medium and large space payloads.
The launch will Yunyao-1 18-20 satellites a total of 3 satellites successfully into the predetermined orbit, the satellite is developed by Changguang Satellite Technology Co., Ltd., the user is Tianjin Yunyao Aerospace Technology Co., Ltd. equipped with GNSS occultation receiver, long-wave infrared camera and other payloads, which can be used for meteorological real-time analysis, numerical weather prediction, space environment early warning and major disaster early warning and other research and applications. The successful launch of this mission verifies the correctness of the overall design of Gravity-1 and the rationality and coordination of the Gravity-1 sea launch system.
Oriental Space was established in 2020, and Zhen**, Jingwei China, etc. are all early shareholders.
Since the establishment of the Gravity-1 project in March 2021, the Oriental Space team has carried out research and development work, conquered the overall design and test technology of sea and land general-purpose medium-sized launch vehicles, the multidisciplinary coupling optimization design technology of solid launch vehicles, the design and manufacturing technology of mass-production-low-cost-large-capacity medium and large rocket structures and devices, and the multi-mode rapid response launch technology of medium-sized launch vehicles, 4 key technology groups, 17 key technologies, and carried out 23 large-scale ground tests. There were 489 individual trials and 1452 trial iterations.
