China News Service, Beijing, February 27th (Chen Hongwei) At 11:06 on February 27th, Beijing time, the Chaohu-1 satellite and the innovative satellite developed by Changsha Tianyi Space Science and Technology Research Institute Co., Ltd. (referred to as "Tianyi Research Institute"). The Xinglei Shen satellite was launched at the Wenchang Space Launch Site aboard the Long March 8 carrier rocket.
The two satellites entered orbit normally, the telemetry parameters were normal, the solar wings and antennas were deployed normally, and the launch mission was a complete success.
Chaohu-1 satellite is the first satellite of "Tianxian Constellation". Its application requirements are proposed by Tiandi Information Network Research Institute (Anhui) Co., Ltd. China Electric Power 38") is the total load.
This is also the second cooperation between Tianyi Research Institute and China Electric Power 38 after the joint development of my country's first commercial SAR satellite Haisi-1.
The successful launch of Chaohu-1 satellite will promote the construction of "Tianxian constellation" and the application of SAR data industry, and help Hefei City, Anhui Province to build a new highland for the aerospace information industry. On-orbit commercial operation.

Compared with the Haisi-1 satellite previously launched by the Tianyi Research Institute, the Chaohu-1 satellite has further optimized the design of the satellite platform and radar load, so that the satellite can be used in imaging width, resolution, maximum imaging time, data transmission, orbit control, etc. The core capabilities have been significantly improved, and the continuous imaging capabilities of regional multi-point targets, precise orbit determination capabilities, and on-orbit AI processing capabilities have been added.
Relying on the Tianyi global automatic ground station network and the characteristics of SAR remote sensing satellites to obtain stable and expected remote sensing images around the clock, the Chaohu-1 satellite will have a 6-hour emergency imaging capability, providing users with more accurate, efficient and reliable SAR satellite remote sensing data. Serve.
Tianyi will also use the two SAR satellites Chaohu-1 and Haisi-1 to provide users with 7x24-hour emergency imaging services, and will rely on the Tianyi Remote Sensing Data Center to form a comprehensive and efficient global Earth observation and data acquisition capabilities. While providing users with automatic archiving/programming image ordering and whole-process perception services, it also assists the construction of my country's emergency system.
Chuangxing Leishen satellite was commissioned by Raytheon Research Institute Mingjian Electronics and Tianyi Research Institute to carry out on-board internal transmission and encrypted storage technology verification of on-board data based on COTS devices, for the subsequent development of low-cost civil aerospace payload accumulation technology and in-orbit technology Experience.
The three parties will also use the networking robustness of low-orbit satellites and ground stations to verify the feasibility of improving the reliability of on-board data storage through distributed network system technology.
The Chuangxing Thor satellite is also equipped with the Aurora 2 detector and the three experimental satellite payloads GRID-03B, GRID-04 and GRID-AICore of the "Tiange Project".
In addition, the satellite-ground fusion distributed network software system is also used on the satellite. The system is jointly developed by Beijing University of Posts and Telecommunications, Huawei Cloud, and Peking University. It will carry out on-orbit QUIC protocol and on-board next-generation core network based on knowledge graph. Meta-function, KubeEdge-based No. 2 edge computing smart base deployment, DOIP on-board payload deployment and other test verifications, among which the on-orbit test verification of the QUIC protocol is the first in the world.
This is the 14th space mission of Tianyi Research Institute. So far, Tianyi Research Institute has successfully sent 25 satellites into space to provide in-orbit services for customers.
