Abstract：Since the dependence of the satellite orbit determination software on the UNIX platform and the UNIX platform’s command-style operation and so on have restricted the development and application of the satellite orbit determination software, we have transplanted the high accuracy satellite orbit determination software from the UNIX platform to the Windows platform.This article describes the steps of this transplantation, mainly including deletion, supplement and modification to the original program according to the difference between Unix platform and Windows platform. We compared the data resulted from the software before transplantation with that after transplantation and the comparison shows that the transplantation is successful.

Key words: satellite orbit determination; Fortran language; software transplantation
