| Abstract: | In order to extend the coverage area of time service in the Changhe II system, the method of using the sky wave on time service for far distance is presented. Based on the experiment data and the theory arithmetic on the field amplitude and time delay of LF sky wave, it is analyzed that the field amplitude and time delay of sky wave vary with the propa- gation distance and the time＂ of all-day. According to the comparison of the field amplitude of sky wave and ground wave, the feasibility of time service by LF sky wave is validated. |
