“The research team has established an end-to-end remote sensing image simulation method for 1A and 1B payloads to meet the real-time processing and algorithm pre evaluation requirements of the "Muduo" remote sensing satellite in orbit. The full link simulation is achieved through multi-source data fusion coupling 6S model, SRF, and MTF, providing basic data support for system verification, on-board algorithm testing, and in orbit intelligent processing algorithm training before satellite launch.”
