随着科学技术水平以及经济水平的不断提升,卫星技术在电视新闻广播行业当中得到了广发的应用,给人们的生活带来了极大的便利。而在卫星通信当中,当太阳、地球与卫星运动在同一条直线上之后,就出现了“日凌”的现象,在这种特殊现象出现之后,卫星通信会受到强大电磁波的影响。在每年的春分与秋分时期,日凌现象会集中出现,在这一时期,太阳与地球的距离最短,这就使得地球所受到的电磁波的影响更为明显,对于卫星信号的传输造成了极大的障碍。因此,必须要强化卫星广播节目地面接收日凌中断及安全播出实现技术的研究,对日凌发生之后的手动操作经验进行总结,更好的把握其发生时期以及持续时间规律,从而采取有效的应对措施,为广播节目的安全播出提供可靠的保障。
With the continuous improvement of science and technology and economic level, satellite technology has been widely used in the television news broadcasting industry, bringing great convenience to people’s life. In the satellite communications, when the sun, earth and satellite movements are on the same straight line, there is a phenomenon that the satellite communications are subject to strong electromagnetic waves after such a special phenomenon occurs. During the annual vernal equinoxes and autumn equinoxes, the phenomenon of Zelin will be concentrated. During this period, the distance between the sun and the earth is the shortest. This will make the impact of the Earth’s electromagnetic waves more obvious and cause great transmission of satellite signals Barrier. Therefore, it is necessary to strengthen the research on the technology of ground receiving interruption and safe broadcasting on the ground of satellite broadcasting, summarize the manual operation experience after the occurrence of Suning and better grasp its occurrence period and the law of duration, so as to take effective Measures to provide safeguards for the safe broadcasting of broadcast programs.
