April 30, 2022/ At 03:30 UTC, China successfully launched Jilin-1 Gaofen 03D (04-07)/04A satellites using the Long March 11H / ChangZheng-11 (Haishe) Yao-3 rocket in the Tai Rui barge stationed at the East China Sea. These satellites successfully entered the 535 km SSO, and the launch mission was a complete success. These five satellites with a total mass of ~270kg in total, listed in the Launch Manifest are optical remote sensing technology satellites funded and developed by Changguang Satellite Technology Co., Ltd. They are mainly used to obtain high-resolution visible light push-broom images and video images. After the five satellites are networked with the in-orbit Jilin-1 satellite, they will provide users in industries such as forestry, agriculture, grassland, ocean, resources, environment, and urban construction with more abundant remote sensing data and product services.

This mission is the 418th flight of the Long March series of launch vehicles and China's 13th launch activity in 2022.

This is the first time that China has achieved a "one-stop" Rocket launch at the sea, mainly due to the integration of final assembly, total testing, port departure, and launch, shortening the mission period by one-third, and reducing transportation costs and possible risks during the transportation process. The high-frequency, batch launch has laid a solid foundation.



The Long March 11 is a solid three-stage carrier rocket was developed by the First Academy of China Aerospace Science and Technology Corporation. It measures 21 m in height and 2 m in diameter, with a launch mass of ~58t and has options of D1.6m/2.0 m fairings, It is mainly used for sun-synchronous orbit and low-Earth orbit payload launch missions, It also supports dedicated launch, multi-satellite launch, Until now, the Long March 11 carrier rocket has carried out a total of 13 launch missions, including 10 land launches and 3 sea launches, sending a total of 58 satellites into space. There will also be one to three sea launches planned this year, including low-inclination circular orbits and sun-synchronous orbits.
