This paper presents a comprehensive analysis of the potential of using differential correction to improve the accuracy of a lunar navigation system based on satellites deployed in lunar orbit. The navigation system provides navigation services for users in the lunar environment and in particular, at low latitudes, using the classical One-Way ranging method and pseudorange measurements from satellites. To evaluate the system's performance, the study proposed the use of the Cramer-Rao Lower Bound, which provides a useful insight into the maximum achievable positioning accuracy. The results showed that the usage of differential correction reduced errors by a factor of up to 8 times compared to the results without correction. The method also showed low sensitivity to the baseline length, which means that the accuracy remained stable regardless of the distance between the reference station and the user.
