At 0250  Hours Hong Kong SAR- Beijing Time 17TH  December 2024 , China- People’s Republic of China- CNSA –China National Space Administration   Successfully launched  Chang Zheng – Long March 2D Carrier Rocket ignited and took off at the Taiyuan Satellite Launch Center Shanxi Province.. at the Taiyuan Satellite Launch Center to successfully send four synthetic aperture radar satellites developed by Galaxy Aerospace into the predetermined orbit. The launch mission was a complete success!

At 2:50 on December 17, 2024, the Long March 2D Yao 99 carrier rocket successfully launched the PIESAT-2 09~12 satellites of the Space Hongtu (pictured in P) and the mission badge at the No. 9 workstation of the Taiyuan Satellite Launch Center . The Long March 2D rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation. The launch service for this mission was provided by the Great Wall Company of China Aerospace Science and Technology Corporation as the general contractor. In order to meet the requirements of the satellite launch layout, this mission used the Ф3800 composite satellite fairing designed by the Eighth Academy for the first time. This type of fairing is widely used in multiple models such as CZ-6C, CZ-6A, CZ-4B/4C, and CZ-2D. The space envelope inside the fairing is larger, which can achieve omnidirectional wave transmission, making the available space of the satellite more abundant and the “communication” between the satellite and the ground more flexible and convenient. Previously, the Long March 6 modified carrier rocket had used composite fairings, and the application effect was good.

In the future, composite fairings will become the shelf-type “optional products” of the Eighth Academy rockets, providing “satellite passengers” with more abundant launch service options. The four satellite users of this mission are Zhuzhou Space Interstellar Satellite Technology Co., Ltd. The satellites have the same technical status and are all low-orbit SAR satellites. They are equipped with high-resolution SAR payloads and on-board intelligent processing, on-board mission planning and other payloads. They have the capabilities of single-satellite high-resolution imaging, multi-satellite high-precision interferometry, on-board intelligent processing and autonomous operation, emergency communication and rapid response, as well as long-term stable data output, and will conduct remote sensing observations and related applications in orbit. Duan Xiao, chief designer of Galaxy Aerospace SAR satellites, introduced that SAR satellites are a general term for earth observation remote sensing satellites carrying SAR payloads, with superior performance such as all-day, all-weather, and high-resolution earth observation. Multiple SAR satellites can increase the revisit rate and carry out a variety of networking applications. They can obtain high-resolution imaging and high-frequency observations, provide regular coverage on a global scale, and achieve millimeter-level deformation measurement of targets such as dams and bridges. They support and serve the application needs of land resources, earthquake monitoring, disaster prevention and mitigation, basic geographic information acquisition, and forestry, and better serve the national economy and people’s livelihood.

酒泉衛星發射中心On 26th January 2022 Wednesday 0744 Hong Kong SAR – Beijing Time  , CNSA –China National Space Administration  Jiuquan Satellite Launch Center – Inner Mongolia – China – People’s Republic of China successfully Launched the International Iconic Chang Zheng 4C – Long March 4C successfully deploying the second launch of China’s aerospace industry this year, the largest SAR satellite in orbit in China- People’s Republic of China  was successfully launched…..  At 7:44 morning on January 26, 2022, the Chang Zheng4C Long March 4C- Yao 29 Carrier Rocket was ignited at the Jiuquan Satellite Launch Center and successfully launched The Land Exploration-1 01 group A satellite was sent into the predetermined orbit. The satellites and rockets launched this time were all developed by the Eighth Academy of China Aerospace Science and Technology Corporation. #L-SAR01 group A satellite successfully launched

The Land Exploration No. 1 01 Group A satellite developed by the Eighth Research Institute of China Aerospace Science and Technology Group Co., Ltd. was successfully launched at the Jiuquan Satellite Launch Center.


The Land Exploration-1 satellite was approved by the National Space Administration. It is the first satellite model launched during the “13th Five-Year Plan” period of the “National Civil Space Infrastructure Medium and Long-term Development Plan”. It consists of two identical L-band synthetic apertures A and B. It is composed of radar (SAR) satellites. After in orbit, it will achieve repeated orbit differential interferometric deformation measurement and interferometric topographic mapping in follow-flight and orbital modes respectively. As the first satellite of the 01 group of Land Exploration 1, the A star of the 01 group of Land Exploration 1 will work in the follow-flying formation mode with the subsequently launched B satellite for a long time, and jointly build the world’s first L-plane for surface deformation interferometry applications.  Band double star constellation. In addition to the long-term flying formation configuration, the double star will also conduct collaborative observation in close-range flying formations to achieve large-scale topographic surveys and improve the ability to obtain under-forest topography. Important support for high-precision terrain data update.

The weight of the 01-group A satellite of Land Exploration-1 is about 3.2 tons, and the total area of ​​the SAR antenna exceeds 33 square meters. It is currently the largest SAR satellite in orbit in China. The satellite operates in a quasi-sun-synchronous orbit at an altitude of 607 kilometers, and is equipped with an advanced L-band multi-polarization and multi-channel SAR payload. It has all-day, all-weather, and multi-mode Earth observation capabilities.


The launch of the 01 group A satellite of Land Exploration No. 1 will realize the independent and controllable differential interferometric SAR data in my country, significantly reduce the dependence on foreign SAR data for geological, seismic, emergency and other industrial applications, and contribute to the realization of global goals such as sustainable development. Provide strong technical support for space observation…

The satellite of Land Exploration-1 will operate in a network with the subsequently launched Chang Zheng-Long March 4C satellite, which can be used in the fields of geology, land, earthquake, disaster mitigation, surveying and mapping, and forestry, providing support for my country’s autonomous satellite detection and prevention of geological disasters. Maintain national resources and ecological security. According to Wei Chun, deputy chief designer and executive chief engineer of the 01 group of Land Exploration No. 1, the double satellite has filled the gap of China’s L-band land exploration satellite. The L-band signal has the characteristics of long wavelength and good penetration. During observation, the L-band signal can pass through a 20-meter-high tree, and accurately measure the height of the ground, instead of only measuring the height of the forest……
