The first star "Chaohu No. 1" of the "Tianxian Constellation" developed by China Electronics Technology 38 successfully obtained Chaohu Lake image in Hefei City, Anhui Province one week after its launch. After interpretation and verification, the image quality is good. At present, the image has been archived for data processing and special application services.
According to reports, the successful reception of the radar echo data transmitted by the satellite, and the high-quality SAR (Synthetic Aperture Radar) image obtained after processing, proves that the satellite was successfully developed and transferred to the on-orbit operation test stage.
After "Chaohu-1" was launched into orbit on February 27, after attitude adjustment, measurement and control digital transmission, and energy system inspection, the radar was officially turned on for imaging, and the image of the target area was downloaded. After being processed quickly by the satellite ground system, the data can be imaged immediately after being downloaded, and the image quality is very good.
"Chaohu-1" is the first commercial networked SAR remote sensing satellite in China. It has continuous imaging capabilities of regional multi-point targets, precise orbit determination capabilities, on-orbit imaging processing, and AI processing functions. Relying on SAR remote sensing satellites With the characteristics of stably obtaining remote sensing images all day, all day, the "Chaohu No. 1" satellite will have a 6-hour emergency imaging capability, which can provide more accurate, efficient, and reliable SAR satellite remote sensing data services. Trusted space-based commercial SAR power.
"Tianxian Constellation" is China's "Shangyao SAR Constellation Construction Project" released by China Electronics Technology 38, and it is also an important part of the development plan of the aerospace information industry in Anhui Province. The "Tianxian Constellation" plans to be based in Anhui and face the world, to build a satellite constellation with SAR remote sensing as the core and tele-remote integration. It is planned to complete the construction of 96 Celestial constellations in three phases, and to achieve sky-level coverage and hourly coverage in Anhui, China, and the world in phases. level revisited.
