"Ling Day" is a satellite communications inside the special phenomenon, when the sun, Earth and satellite motion in a straight line together, this time will interfere with satellite communications. May Ling phenomenon occurs twice a year, it will focus on,namely when the vernal equinox and autumnal equinox, in both periods, the shortest distance between the Earth and the sun, the electromagnetic radiation emitted by the sun on the planet is the most intense. Possible transmission of the satellite signal will cause some of the obstacles on the ground receiving systems receive satellite signals at the same time also received a large number of solar radiation clutter, it does not recognize the useful signal, resulting in signal degradation or even interrupted.Television programs on the central, provincial, autonomous regions and municipalities directly under the stars, as in radio and television programs of cable television head-end station provides a large number of high-quality sources. As directly under the State Press and Publication Administration of Radio broadcast the launch pad in the country a total of 48 grass-roots stations, 15 control center, has become an important form of broadcast coverage, I was working as a radio transmitting station 48,one of the grassroots, where I the sector control room inside the station, a room is to provide high-quality signal source to do security work, but Japanese Ling interrupts directly affect satellite ground receiving and broadcasting daily radio and television signal sources, therefore, to understand day Ling interrupts, to keep abreast of the different areas of satellite ground receiving stations date and time and the laws of Japan Ling transmission occurs when the broadcast program, take the necessary measures,pre-configured to ensure the secure transmission of launching the program running.
