abstract = "{Laser interferometry plays a crucial role in laser ranging for high-
precision space missions such as GRACE (Gravity Recovery and
Climate Experiment) Follow-On-like missions and gravitational
wave detectors. For such accuracy of modern space missions, a
precise relativistic model of light propagation is required.
With the post-Newtonian approximation, we utilize the Synge
world function method to study the light propagation in the
Earth's gravitational field, deriving the gravitational delays
up to order c$^{‑4}$. Then, we investigate the influences of
gravitational delays in three inter-satellite laser ranging
techniques, including one-way ranging, dual one-way ranging, and
transponder-based ranging. By combining the parameters of Kepler
orbit, the gravitational delays are expanded up to the order of
e$^{2}$ (e is the orbital eccentricity). Finally, considering
the GRACE Follow-On-like missions, we estimate the gravitational
delays to the level of picometer. The results demonstrate some
high-order gravitational and coupling effects, such as
c$^{‑4}$-order gravitational delays and coupling of Shapiro and
beat frequency, which may be non-negligible for higher precision
laser ranging in the future.}",
