In the satellite navigation system, the altitude accuracy of an regular receiver is usually poor. This paper proposed a method that uses satellite positioning assisting differential barometric altimetry under the condition without the data of pressure base stations. It also proposed using barometric altimetry assisting satellite positioning when there’re fewer satellites. And we discussed the method of RAIM algorithm with differential barometric altimetry. The result shows: the improved method of utilizing the differential barometric altimetry to assist satellite positioning can locate which there are 3 visible satellites. And it can also improve positioning accuracy when there are fewer visible satellites and the detection rate of the single-satellite fault is improved.
