The invention discloses a high-dynamic-rate high-speed satellite data transmission method and system, and relates to the technical field of satellite communication. How to realize higher-rate and larger-capacity data transmission under the condition that satellite hardware resources, bandwidth, power and data transmission time are limited in the prior art becomes an urgent problem to be solved. According to the scheme provided by the invention, the high-dynamic-rate high-speed satellite data transmission system is realized based on a high-speed satellite data transmission method, and the system comprises a data processing unit which is used for receiving high-speed data of a load camera through an FPGA module, processing the data to obtain an intermediate frequency signal, and outputting the intermediate frequency signal to a high-speed DAC module; the data digital-to-analog conversion unit is used for carrying out digital-to-analog conversion and outputting a processed intermediate frequency signal; and the
