| Abstract: | The emphasis in this work introduces the Plans of PL-only positioning system and analyzes the positioning accuracy on different users through the medium of Dilution of precision.According to a series of research on the problems about air user with emphasis,it has made some analysis and simulations on this project.In the course of simulation,there are some problems,such as singular swath of the distribution of Dilution of precision,the lower accuracy and so on.In this work,the different distribution of PL and the increasment of the PL number are used to solve the problems. |
