【#Tech24H】On March 20, the "PowerChina-1" satellite passed its factory acceptance review, marking the successful completion of its development. The "PowerChina-1" satellite has achieved multiple technological breakthroughs, including lightweight design, precise positioning, and "high-definition imaging". It operates in a sun-synchronous orbit at an altitude of 500±50 kilometers, with a total mass of 298 kilograms. The satellite establishes a complete radar satellite technology chain encompassing payload, platform, launch, telemetry, tracking and control, data transmission, and application. It offers a maximum resolution of sub-meter level, a revisit period of 11 days, and a designed operational lifespan of 5 years. It is applied in deformation monitoring of large-scale engineering structures under harsh environments and complex terrain and geological conditions, as well as in geological disaster identification and early warning.
