Exact general relativistic observation equations for the GAIA concept were derived for a static sphere, i.e., with only stellar angular coordinates as unknowns. These equations were then put to test in an end-to-end simulation of the current baseline mission. Although the applicability of the present model is limited to the case of an observer in the gravitational well of a spherical non-rotating Sun, the results show that, despite cumbersome formalism, measurements of angular distances among stars good to ~100 microarcsec (as expected for stars of V=16 mag) can be modeled to yield estimates of the relativistic astrometric parameters with errors of ~20 microarcsec after only one year of satellite operations.
