The world’s first low-inclination remote sensing constellation has launched its first satellite!
China, People’s Republic of China. … At 11:39 Beijing time on October 21, 2026, the Ceres-1 sea-launched (YY-8) carrier rocket was launched from the “Dongfang Aerospace Port” launch ship in the Yellow Sea near Rizhao, Shandong, and successfully sent the Xiguang-4 01 satellite into a near-Earth orbit with an altitude of 541 kilometers and an inclination of 39 degrees.
The mission’s codename is “The Sea Facing Guangzhou”. The mission payload, “Xiguang-4” 01 satellite, is a small low-orbit optical remote sensing satellite developed and manufactured by Guangzhou University, with Guangdong Tianyuan Technology Co., Ltd. taking the lead and Xi’an Zhongke Xiguang Aerospace Technology Group Co., Ltd. specifically undertaking the research and development. It is an experimental satellite for optical remote sensing technology, operating in a low-inclination near-Earth orbit at an altitude of 500-550 kilometers.
The Xiguang-4 01 satellite is the first satellite (verification satellite) of the Wuyang constellation. It is equipped with an electric propulsion system and a high-speed data transmission link. It carries a 0.5-meter resolution high-resolution camera, a 2-meter resolution multispectral camera and a 30-meter resolution wide-swath infrared payload, and adopts a 300-kilogram satellite platform.
As a verification satellite for the constellation, the “Wuyang” constellation’s precursor satellite A (“Xiguang-4” 01 satellite) will fully undertake the verification of the entire chain of technologies, including orbit adaptation, multi-payload imaging, electric propulsion on-orbit scheduling, and satellite-to-ground link, and acquire on-orbit measured engineering data to lay a solid technical foundation for subsequent large-scale operational satellite networking.
The “Wuyang” constellation is the world’s first low-inclination remote sensing satellite constellation, jointly promoted by the Guangzhou Municipal Government, the National Information Center, and Guangzhou University, and operated and applied by Tianyuan Technology. Targeting the economically vibrant mid-to-low latitude region between 39 degrees north and south latitude, it aims to create China’s first high-resolution, wide-swath, full-spectrum, and intelligent aerospace information service system for low-latitude regions. The “Wuyang” constellation comprises 3 precursor satellites and 25 operational satellites.

Ceres-1 is a small solid-propellant launch vehicle developed by Galactic Energy Corporation. It adopts a four-stage tandem configuration, with three solid stages and a room-temperature liquid final stage. The rocket is about 20 meters high and 1.4 meters in diameter, equipped with a 1.6-meter diameter fairing, with a takeoff mass of about 33 tons and a takeoff thrust of 60 tons. Its payload capacity to low Earth orbit (LEO) at an altitude of 200 kilometers is 420 kilograms.

This mission once again validated the entire process of the rocket, from final assembly and testing, sea transport to launch, further solidifying the foundation for future routine and high-frequency launches.
The rocket for this mission was assembled and shipped from the Oriental Spaceport Industrial Park, with the launch ship and other maritime launch services provided by Oriental Spaceport. The “Oriental Spaceport” launch ship is equipped with a “sea-based launch attitude real-time control system” with completely independent intellectual property rights. Through dynamic compensation, it controls the impact of ship swaying on the rocket launch attitude to a very small range, enabling precise launches even in sea state 4.

This mission marks the second launch of the Ceres-1 carrier rocket in 2026, the 73rd launch in China, and the 246th launch worldwide. It is also the 7th sea launch and the 24th launch overall for the Ceres-1 carrier rocket.
