| Abstract: | Distance measuring equipment/precision (DME/P) is a newly developed radio navigation system in the world. It is more precise than conventional distance measuring equipment(DME/N) . In this paper, three typical flying profiles for DME/P accuracy evaluation test are introduced, the classification method of distance measuring error and the distribution characteristics of accuracy are analyzed in detail. Furthermore, a dynamic and precise evaluation for the DME/P accuracy is made by using a proper digital filter and data processing method. |
