AbstractSince 1976 the International Astronomical Union (IAU) has made a series of resolutions on the reference systems and time scales for high precision data processing in the framework of general relativity. This article reviews those resolutions that closely relate with the ASTROD project. We give our comments on how to meet the IAU resolutions in the future ASTROD data processing and what kind of works that need to be done further. For example, the self-gravitation terms should be included in the motion equation of the Earth, which is not included in the present DE ephemerides. And the effect of the Sun's figure on the motion of photons should be considered, which is partly neglected in the IAU metric. We also give the metric and the motion equations for both planets and photons in the parameterized post-Newtonian (PPN) formalism. A further improvement of the framework to the second post-Newtonian (2PN) precision would be necessary for the ASTROD project.
