The Space Interferometry Mission, or SIM, [...] was a planned space telescope proposed by [...] (NASA) [...] cancelled in 2010. [...] Interferometric measurements of stellar positions over the course of the mission would have permitted SIM to precisely measure the distances between stars throughout the Milky Way.

Relativistic stellar aberration for the Space Interferometry Mission
Slava G. Turyshev, JPL
"""
We address the issue of general relativistic deflection of light by [...] celestial bodies in the solar system. [...] the need to correct for the gravitational bending of light [...] positions of the outer planets presently may not have a sufficient accuracy for the precision astrometry. However, SIM may significantly improve those simply as a by-product of its astrometric program. [...] with SIM is expected to be of the order of σ(α) = 8 µas [OZ: Kip Thorne said 4 µas]

See Table 1,2,3,4
