Summary:The invention discloses a satellite-borne DSP (Digital Signal Processor) software partial reconstruction uploading method, which comprises the following steps of: setting target segments. Codes and. Datas, which are required to be updated, in a SECTION segment definition of a link script file; the target code and the data are assigned to the segment.codes and the segment.datas respectively, and an executable file is generated through compiling; converting the executable file into a binary file; the binary file and the lookup table are programmed into a FLASH; and during uploading, the modified target mirror image is sent, after a receiving end receives an uploading request, uploading information is verified, and a target file is written into the FLASH if a result is correct. According to the method, large mirror image reliable updating of the on-orbit satellite load is realized, the volume of an uploading program is reduced, the modification of a storage space is reduced, the uploading time is saved, the uplo
