The satellites of the GNSS system are equipped with several atomic clocks; however, their high accuracy has a limit. The corrections for the offset of the clocks are transmitted in the "navigation message". These corrections are calculated by reference ground stations and are used to compensate for the continuous deviation of the clocks. The uncertainty in the receiver clock, which is much less accurate since it is not an atomic clock, is considered an additional unknown, hence the need for at least four satellites.
