About
Chaohu-1 is Spacety’s second commercial C-band SAR remote-sensing satellite, launched 27 February 2022 from Wenchang Satellite Launch Center alongside the Thor smart satellite, continuing deployment of Spacety’s SAR constellation and making Spacety the first company in China to deploy and operate a commercial SAR constellation. Compared with Hisea-1, Chaohu-1 further optimizes the satellite platform and SAR payload design, significantly improving spatial resolution, swath size, single-orbit imaging duration, data downlink, and orbit control. It adds continuous multi-target imaging, precise orbit determination, and in-orbit data processing using Artificial Intelligence. Using Spacety’s global ground-station network, Chaohu-1 delivers emergency imaging data within 6 hours of acquisition, and supported a contract with the North China University of Water Conservancy & Electric Power for SAR-based water-resources monitoring applications. This was Spacety’s 14th space mission, bringing its total to 25 satellites launched.
