For software to be installed for upgrade, in addition to the executable program, the software data package also includes an incremental executable program update package relative to the older version of the software.

The incremental executable program update package can be produced by first obtaining the executable programs of the new and old versions of the software, and then generating a patch file by comparing the program differences. In the traditional differential update algorithm, the binary comparison results of the old and new files are usually required to be completely consistent, but this will result in a larger update package. The update of data processing software usually involves partial modification of the source code, and the updated code will cause regular movement of the entire block. Most of the object code generated by the same code after the source code file is compiled is the same, and a small part of the object code address displacement data that needs to be updated also has the same displacement amount. Taking this feature into account, the incremental executable program update package can be generated using the incremental update algorithm bsdiff. This algorithm mainly uses suffix sorting or hashing algorithms to form a string index of the old version of the code, then uses the index to compare the new version of the code, generates a difference file and an incremental executable program update package file, and finally combines the necessary index control Information is compressed into software packets. After generating the software data package, upload the software data package to the first node satellite through uplinks such as measurement and control.

For example, the installed version information is that the version of the installed software A1 is 2.0, and the version information to be installed is that the version of the software A1 to be installed is 3.0. It can be determined that the installed software needs to be updated, thereby determining that the software comparison result is that the installed software needs Make an update. For another example, the installed version information is that the version of the installed software A1 is 2.0, and the version information to be installed is that the version of the software B1 to be installed is 1.0. It can be determined that the installed software does not need to be updated, and the to-be-installed software needs to be installed in the second node satellite. Software B1.
