In this paper, expressions for high-precision simulation of multi-GNSS observations received in low Earth orbit are given. Based on this observation model, the real spacecraft orbit was refined. Based on real data from the GRACE space project, the results were compared with simulated measurements from foreign software. The average deviation in determining the spacecraft location was 18 mm, which confirms the correctness of the described observation model.
