| Abstract: | A modified method for improving positioning precision of passive BeiDou system in middle-low latitude area is brought forward. The differences between satellites are used and the height constraint condition is added in the procedure of improving. Compared with the traditional method, a higher precision and better stability can be achieved. Based on the analysis of the emulation result, it can be shown that the positioning precision can reach 50~200 meters in middle-low latitude area. |
